Full textAbstract:
The knowledge of bioacoustics of the Neotropical crickets (Orthoptera, Gryllidea) is incipient, despite the great species diversity in the region. There are few cricket song-files deposited in the major World Sound Libraries, compared to other groups such as birds and amphibians. In order to contribute to the knowledge of the bioacoustics of Brazilian crickets, we organize, analyze and make available at Fonoteca Neotropical Jacques Vielliard (FNJV) and Orthoptera Species File (OSF) our bank of cricket songs. We deposited 876 cricket’s song files in the FNJV, belonging to 31 species and 47 sonotypes. The songs were field/lab recorded, and all individuals were collected to improve species/sonotypes taxonomic determination accuracy. We present photos (in vivo) of most recorded crickets, as well as calling song spectrograms to facilitate the species/sonotype recognition. Samples of the songs can be found online on the FNJV website, using the codes available in this work, as well as on the OSF, linked to the species name. As a result, we advance the knowledge of the songs of crickets and the current perspective of the Brazilian cricket bioacoustics. We encourage researchers to share with the public their collections of their cricket file songs both in the FNJV and the OSF.

Insects have a sophisticated ability to navigate real environments. Virtual reality (VR) is a powerful tool for analyzing animal navigation in laboratory studies and is the most successful when used in the study of visually guided behaviors. However, the use of VR with non-visual sensory information, such as sound, on which nocturnal insects rely, for analyzing animal navigation has not been fully studied. We developed an auditory VR for the study of auditory navigation in crickets, Gryllus bimaculatus. The system consisted of a spherical treadmill on which a tethered female cricket walked. Sixteen speakers were placed around the cricket for auditory stimuli. The two optical mice attached to the treadmill measured the cricket’s locomotion, and the sound pressure and direction of the auditory stimuli were controlled at 100 Hz based on the position and heading of the cricket relative to a sound source in a virtual arena. We demonstrated that tethered female crickets selectively responded to the conspecific male calling song and localized the sound source in a virtual arena, which was similar to the behavior of freely walking crickets. Further combinations of our system with neurophysiological techniques will help understand the neural mechanisms for insect auditory navigation.

We present a sensor that can measure light and wirelessly communicate the measurement, without the need for an external power source or a battery. Our sensor, called cricket, harvests energy from incident light. It is asleep for most of the time and transmits a short and strong radio frequency chirp when its harvested energy reaches a specific level. The carrier frequency of each cricket is fixed and reveals its identity, and the duration between consecutive chirps is a measure of the incident light level. We have characterized the radiometric response function, signal-to-noise ratio and dynamic range of cricket. We have experimentally verified that cricket can be miniaturized at the expense of increasing the duration between chirps. We show that a cube with a cricket on each of its sides can be used to estimate the centroid of any complex illumination, which has value in applications such as solar tracking. We also demonstrate the use of crickets for creating untethered sensor arrays that can produce video and control lighting for energy conservation. Finally, we modified cricket's circuit to develop battery-free electronic sunglasses that can instantly adapt to environmental illumination.

Full textAbstract:
Food safety for cricket production is a crucial factor in producing edible crickets with safety for consumers and sustainability for two-spotted (Gryllus bimaculatus) as well as house (Acheta domesticus) cricket production. This study was conducted by simultaneously rearing two cricket species, comprising two-spotted crickets (G. bimaculatus) and house crickets (A. domesticus). A total of 16 rearing crates were used for the present study, which were allocated into 8 rearing crates for each studied cricket species, including paper egg cartons. Cricket eggs were incubated in the rearing crates. Once the crickets hatched, tap water and powdered feed were provided ad libitum throughout the experiment. At the end of this study (35 and 42 days for the two-spotted and house crickets, respectively), all crickets were harvested, rinsed in tap water, and boiled in water for 5 min. During the rearing and harvesting processes, samples were collected from various potential contamination points for bacteria, including E. coli and Salmonella spp. There were samples of the initial input (feed, drinking water, and staff hands), rearing environment (water pipe, crate wall, living cartons, frass, and cricket surface), and harvesting crickets (harvested, washed, and boiled crickets), with a 2-week sampling interval, except for the last round of sampling for the two-spotted crickets. Subsequently, all samples were submitted to isolate and identify contaminated bacteria. The samples from the last round of sampling for both kinds of crickets were submitted to quantify the level of contamination for E. coli and Salmonella spp., including antimicrobial resistance by the disk diffusion method for the positive isolate. The results showed that bacterial contamination was found in the rearing of both cricket species, primarily involving Klebsiella spp. and Enterobacter spp., mainly found in prepared drinking water and the water pipes of drinking water supply equipment, which are potential sources of contamination with cricket frass. E. coli was found in 4.8% and 4.3% of the two-spotted and house crickets, respectively, while no presence of Salmonella spp. was detected in any submitted samples. The quantification of E. coli and Salmonella spp. indicated E. coli contamination near the water pipe and the frass of two-spotted crickets, but Salmonella spp. was undetectable in both two-spotted and house crickets. The antimicrobial resistance of isolated E. coli mainly involved penicillin G, amoxicillin, ampicillin, erythromycin, lincomycin, and tiamulin. Thus, good farm management with proper sanitation practices (such as cleaning and keeping the environment dry), as well as boiling crickets during the harvesting process, may help ensure the safety of edible cricket production.

<span lang="EN-US">Due to the effects of the change in temperature that have resulted in dramatic changes in the livelihoods of crickets. Hence, the implementation of cooling technologies is an important factor for alleviating these negative consequences. This research presents the experimentally investigate the feasibility of employing a thermoelectric cooler in combination with an evaporative air-cooling system for two-spotted cricket (Gryllus bimaculatus) rearing process. The proposed cooling system has been installed to reduce the temperature that appropriate for the cricket rearing. The experimental results show that the product air temperature of cricket rearing pens with thermoelectric evaporative air-cooling system decreases form ambient air. The average temperature of the cricket rearing pens with thermoelectric evaporative air-cooling system is 29.66 °C, with the highest temperature at 31.40 °C. While the average temperature of the cricket rearing pens without thermoelectric evaporative air-cooling system is 33.75 °C, with the highest temperature at 37.10 °C. Furthermore, this research also shows that this proposed system can improve cricket survival rate. The crickets that reared in the prototype system have a survival rate of 88.5%, while survival rate of crickets in an uncontrolled pen is 67.2%. This paper provides a potential of applying thermoelectric evaporative air-cooling for cricket farming.</span>

Full textAbstract:
The toxicity of thiamethoxam against nymphs and adults of the tawny mole cricket, Scaptericus vicinus Scudder, and the southern mole cricket, S. borellii Giglio-Tos, was evaluated in the field and greenhouse. Thiamethoxam demonstrated varying levels of mole cricket control in the field studies. The performance of the insecticide appeared to be related to the application timing and formulation. Applications made in late June 1998 provided the best mole cricket control compared to the other two field studies. The LC50 and LC90 values of thiamethoxam against adult southern mole crickets were 1,816 and 9,978 ppm, respectively, using a greenhouse bioassay technique. Another greenhouse study indicated that thiamethoxam at application rates ranging from 154 to 616 g (ai)/ha did not provide acceptable control against medium sized nymphs (third to six instars) of tawny and southern mole crickets. An additional study with fipronil, bifenthrin, and deltamethrin compared mortality of the two species of mole crickets in greenhouse bioassays. In these assays, all insecticides resulted in different levels of mole cricket mortality between the two species. The use of bifenthrin resulted in significantly higher mortality of tawny than southern mole crickets.

Full textAbstract:
We examined the potential of cricket farming as an innovative solution to improving household nutrition in Laos, where edible insects are already part of traditional diets. We conducted research with a total of 40 rural households in Central Laos, in which small-scale cricket farming was introduced to 20 intervention households. Nutritional situation and changes of all households and cricket production and consumption of the intervention households were assessed. Malnutrition was prevalent amongst the study population and we found indications for dietary inadequacies. Despite fluctuating harvest results and some production failures, most intervention households successfully produced and harvested crickets over five production cycles. Cricket farming was not only appreciated by the project participants, but also spread to non-project households. 70% of the total cricket harvest were used for own consumption and crickets were eaten by all family members, including small children and women, in amounts that improved nutritional adequacy during the brief period following harvest. To increase the nutritional impact, production has to be stabilised and adapted to provide a more continuous supply of crickets over the year.

Full textAbstract:
In the concept of novel food, insects reared under controlled conditions are considered mini livestock. Mass-reared edible insect production is an economically and ecologically beneficial alternative to conventional meat gain. Regarding food safety, insect origin ingredients must comply with food microbial requirements. House crickets (Acheta domesticus) and Jamaican field crickets (Gryllus assimilis) are preferred insect species that are used commercially as food. In this study, we examined cricket-associated bacterial communities using amplicon-based sequencing of the 16S ribosomal RNA gene region (V3–V4). The high taxonomic richness of the bacterial populations inhabiting both tested cricket species was revealed. According to the analysis of alpha and beta diversity, house crickets and Jamaican field crickets displayed significantly different bacterial communities. Investigation of bacterial amplicon sequence variants (ASVs) diversity revealed cricket species as well as surface and entire body-associated bacterial assemblages. The efficiency of crickets processing and microbial safety were evaluated based on viable bacterial counts and identified bacterial species. Among the microorganisms inhabiting both tested cricket species, the potentially pathogenic bacteria are documented. Some bacteria representing identified genera are inhabitants of the gastrointestinal tract of animals and humans, forming a normal intestinal microflora and performing beneficial probiotic functions. The novel information on the edible insect-associated microbiota will contribute to developing strategies for cricket processing to avoid bacteria-caused risks and reap the benefits.

Full textAbstract:
The house cricket, Acheta domesticus, is a commonly reared insect for food and feed purposes. In 1977, a report described a colony collapse, which was caused by the single-stranded DNA virus Acheta domesticus densovirus (AdDV). Currently, there are no confirmed A. domesticus colonies free of AdDV, and viral disease outbreaks are a continuous threat to A. domesticus mass rearing. Correlations between cricket rearing density or temperature and AdDV abundance have been hypothesized, but experimental evidence is lacking. Optimised rearing conditions, including temperature and density, are key to cost-effective cricket production. In this study, house crickets were subjected to different combinations of rearing density (10, 20, 40 crickets per box) and temperature (25, 30, 35 °C) to study the effect on cricket survival, biomass, and AdDV abundance. Rearing temperature affected had a minor effect on survival, which ranged between 80 and 83%. Total cricket biomass increased with higher temperatures and higher densities. Viral abundance in crickets at the end of the rearing period was variable; however, high rearing density seemed to result in higher AdDV abundance. At 35 °C, a temperature considered suboptimal for house cricket production, viral abundance tended to be lower than at 25 or 30 °C.

This paper describes our trials in developing automated interaction systems with crickets by using a micro mobile robot for attracting pheromone behavior. The cricketGryllus bimaculatusmodifies its behavior based on experience that is based on pheromone interactions between individuals. In developing systems, a micro mobile robot with a cricket’s head is controlled based on online visual tracking information. In this paper, we describe implementing automated micro mobile robot control based on image processing and attempt experimental trials in interaction between the cricket and micro mobile robot. The cricket shows a typical response to the pheromone stimulus for approaching by the micro mobile robot. Results also show that the developed system could contribute to novel biological research, for example, manipulable experimental conditions for interactive experiments.

Full textAbstract:
The so-called hua niao yu chong (“flower, bird, fish, insect”) culture of China is a tradition related to the growth and raising of small and easy-to-care-for plants and animals. Typical of this culture is that of fighting crickets. Cricket fights, between two male crickets, is an amusement especially popular among urban dwellers. In the past it was followed by the emperor and the nobility, by the rich and by intellectuals such as the literati. Because of this, previous research into Chinese culture has tended to emphasize only the glamorous side of cricket fighting and paid scant attention to those who sustained it in the background. Nevertheless we cannot ignore those people in rural areas who go out to catch the crickets that will provide amusement for cricket-fight aficionados in the cities. In fact, both urban dwellers, as consumers, and farmers, as providers, sustain the culture of cricket fighting, but there are wide differences between them in terms of folk knowledge and skills. The knowledge and skills of the farmers who hunt crickets are concerned closely with the habits of crickets and resemble the type of knowledge that is based on observation, and so can be explained in terms of entomological ecology and behavioural science. Urban aficionados, on the other hand, care for crickets in terms of how they think crickets should live, quite differently from their natural habitat. They have anthropomorphized them, rearing them as if they were associating with other human beings, and in general have inserted human values into their lives.

Full textAbstract:
We investigated the transmission dynamics of a sexually transmitted nematode, Mehdinema alii, in the decorated cricket, Gryllodes sigillatus. Adult crickets were experimentally inoculated with infective stages of the nematode, called dauerlarvae, to determine the role of the female cricket in nematode transmission. We found that female crickets serve only as a means of mechanical transmission, so nematodes do not require passage through a female cricket to be infective. Dauerlarvae were experimentally placed on the genitalia of both sexes. In the male, the dauerlarvae migrated into the gut and proceeded to develop into adult nematodes, whereas those that were inoculated into the female genitalia failed to migrate into the gut. When dauerlarvae were inoculated directly into the female rectum, the nematodes failed to develop. Therefore, the female gut is not a suitable environment for nematode development. Dauerlarvae persisted in the female cricket for up to 12 days post inoculation and remained infective to male crickets.

Processing crickets into a versatile dry powder ingredient may facilitate their utilisation in a variety of food products. Three dried cricket ingredients – oven-roasted cricket meal; the same ingredient milled to a smaller particle size, called oven-roasted cricket powder; and spray-dried cricket powder – were prepared and evaluated for their physical, nutritional and sensory properties. Oven-roasted cricket powder had a smaller range of particle sizes and fewer large particles compared to spray-dried cricket powder. Consumer panellists rated oven-roasted cricket powder as less gritty than the other two ingredients. Prepared as a protein drink, oven-roasted cricket powder had the highest viscosity and an intermediate sedimentation rate. Differences between treatments existed in proximate analysis parameters and nutrients, but amounts were similar to previously reported values for cricket powders. Consumer panellists preferred the smaller particle-sized oven-roasted powder over larger particle-sized oven-roasted meal or the spray-dried powder ingredients, as indicated by all sensory acceptance attributes, preference ranking, and purchase likelihood.

Animals often rely on events in their environment that provide information (i.e. experience) to alter their future decision-making in ways that are presumed to be beneficial. Such experience-based learning, however, does not always lead to adaptive decision-making. In this study, we use the omnivorous harvestman Heteromitobates discolor to explore the role of past diet on subsequent food choice and survival. We first tested whether a short-term homogeneous diet (rotten crickets, fresh crickets or dog food) influenced subsequent food choice (rotten cricket versus fresh cricket). We next examine the impact of diet on survival. We found that following experience with a homogeneous cricket diet, adult harvestmen displayed a learned preference for familiar food, regardless of whether it was rotten or fresh crickets; individuals experiencing dog food were equally likely to choose rotten versus fresh crickets. We additionally found that individuals that ate rotten crickets suffered shorter survival than those that ate fresh crickets. Together, our results suggest that the diet an individual experiences can lead to maladaptive food preferences—preferences that ultimately result in reduced longevity.

AbstractSignificant advances in biophysical methods such as next-generation sequencing technologies have now opened the way to conduct evolutionary and applied research based on the genomic information of greatly diverse insects. Crickets belonging to Orthoptera (Insecta: Polyneoptera), one of the most flourishing groups of insects, have contributed to the development of multiple scientific fields including developmental biology and neuroscience and have been attractive targets in evolutionary ecology for their diverse ecological niches. In addition, crickets have recently gained recognition as food and feed. However, the genomic information underlying their biological basis and application research toward breeding is currently underrepresented. In this review, we summarize the progress of genomics of crickets. First, we outline the phylogenetic position of crickets in insects and then introduce recent studies on cricket genomics and transcriptomics in a variety of fields. Furthermore, we present findings from our analysis of polyneopteran genomes, with a particular focus on their large genome sizes, chromosome number, and repetitive sequences. Finally, how the cricket genome can be beneficial to the food industry is discussed. This review is expected to enhance greater recognition of how important the cricket genomes are to the multiple biological fields and how basic research based on cricket genome information can contribute to tackling global food security.

In response to ultrasonic stimuli, tethered flying crickets perform evasive steering movements that are directed away from the sound source (negative phonotaxis). In this study we have investigated the responsiveness to ultrasound of neurons that descend from the cricket brain, and whether flight activity facilitates the responsiveness of these neurons. 1. Ultrasonic stimuli evoke descending activity in the cervical connectives both ipsilateral and contralateral to the sound source. 2. Both the amount of descending activity and the latency of this response in the cervical connectives are linearly correlated with ultrasonic stimulus intensity, regardless of the cricket's behavioral state. 3. Flight activity significantly increases the amount of descending activity evoked by ultrasound at all stimulus intensities, and significantly decreases the latency of the response in the cervical connectives compared with non-flying crickets. Flight activity, however, does not significantly affect the activity in an interneuron (Int-1) carrying ultrasound input to the brain. Thus, the increase in the amount of descending activity produced during flight activity is due to the integration of input from Int-1 and the flight motor system to ultrasound-sensitive neurons in the cricket brain. 4. Descending units recorded in the cervical connectives originate in the cricket brain. A reduction in the amount of descending activity is correlated with a decrease in the magnitude of the negative phonotactic response of the abdomen during flight activity, suggesting that these descending units play a role in eliciting negative phonotaxis.

Abstract The need for high-protein foods strives for the food sector to find an efficiently produced protein sources. One of the most efficient and fast reproducing protein sources are insects containing high levels of protein, nutrients and vitamins. Crickets are one of the most consumed insects, especially in Southeast Asia. Despite the potential of crickets as sources of protein, cricket flour is very little used and studied in Indonesia. This study aimed to develop the best formulation for cricket flour-enriched cookies with a high nutrient and consumer acceptability. As the main ingredient of cookies, wheat was substituted by 5%, 10% and 20% of cricket flour. Among the tested formula, cookies with the 5% and 10% cricket flour showed the highest overall organoleptic acceptability. These cookies are significantly higher in protein and lower in fiber and carbohydrate compared to cookies made with wheat flour.

The objects of this study were five male crickets and one female cricket that had been isolated for twenty-four hours. This research is an exploratory descriptive study observing all male and female cricket (gryllus bimaculatus) behaviors. The research method used is ad libitum which is observing all visible activities, both social behavior and daily behavior of male and female crickets. Retrieval of data using direct observation, recording sounds and then recorded in the observation sheet, observation notes, and documentation tools. The data that has been collected is then analyzed using descriptive analysis techniques that describe the behaviors that arise during observation. The results showed that the behavior that is often performed by crickets is sounding, eating, climbing, mating and attacking other crickets. Crickets perform sounding behavior to attract the attention of female crickets, show their existence and to defend their territory and food sources. crickets also often climb, to escape from the container because crickets want to live freely. Crickets perform eating behavior to maintain life and will show aggressive behavior when fighting over food and when maintaining their partners. Female crickets will mating if captivated by male crickets.</em></p>

Full textAbstract:
In Indonesia, crickets (Gryllus sp.) are used as feed for pet animals, especially insectivorous animals, one of which is the kalung/collared cricket. Collared crickets have a short life cycle, high egg hatchability, fast growth, low feed conversion, and have softer body skin that is preferred by birds and other insectivorous animals. Feed is very important in intensive cricket rearing, especially in hatching crickets. The feed given to crickets is generally in the form of concentrates and leaves. This study aims to determine the effect of giving concentrates and market waste (kale, cabbage, cassava leaves) on the performance of collared crickets (Gryllus bimaculatus). This research was conducted at the Livestock Biology Laboratory, Department of Animal Science, Faculty of Agriculture, Universitas Sumatera Utara, from March to April 2020. This research was conducted experimentally using a completely randomised design (CRD) consisting of 4 treatments and 5 replications. The treatments consisted of P0 = 100% market waste, P1 = 75% market waste + 25% concentrate, P2 = 50% market waste + 50% concentrate, P3 = 25% market waste + 75% concentrate. The results of this study showed that the provision of concentrate and market waste (kale, cabbage, and cassava leaves) had no significant effect on the performance of collared crickets. The average mortality in this study was 6.4%, the feed consumption value was 8.74 g/head/day, the average body weight gain was 0.43 g/head/day, and the average feed conversion was 20.71 g/head. In conclusion as there is no difference between each treatment on cricket performance, the 100% market waste treatment can be used for collared cricket feed.

Cricket farming can have a positive impact on rural development and rural economy in low- and middle-income countries. Moreover, crickets have the potential to address food and nutrition insecurity and promote food sovereignty through the promotion of local production and consumption. This paper presents and discusses five complementary studies conducted in Thailand, Cambodia, Lao People's Democratic Republic (Lao PDR), the Democratic Republic of the Congo (DRC) and Kenya. Cricket farming is being promoted in these countries under research projects, public-private partnerships, NGOs and international organisations. In the majority of the countries, cricket farming is still in its infancy and research into how to improve cricket farming systems is still on-going. Cricket farming in Cambodia, Lao PDR, DRC and Kenya remains relatively limited, and many farmers are still a part of pilot projects. In each of the five regions, different cricket species have been a part of traditional diets. As discussed in this paper, many of the potential benefits of the production and consumption of crickets have not yet been realised in many cases due to: (1) lack of adequate support and awareness from stakeholders (especially government agencies); (2) unknown trade volumes; (3) high costs of inputs; and (4) cultural taboos. The information presented in this paper will be especially useful to stakeholders from governmental institutions, non-governmental organisations, civil society organisations and research institutions.

Full textAbstract:
The Food and Agriculture Organization of the United Nations (FAO) estimates that more than 500 million people, especially in Asia and Africa, are suffering from malnutrition. Recently, livestock farming has increased to supply high-quality protein, with consequent impact on the global environment. Alternative food sources with high nutritive values that can substitute livestock demands are urgently required. Recently, edible crickets have been promoted by the FAO to ameliorate the food crisis. In this review, the distribution, nutritive values, health-promoting properties (antioxidant, anti-inflammatory, anti-diabetic and anti-obesity), safety, allergenicity as well as the potential hazards and risks for human consumption are summarized. Cricket farming may help to realize the United Nations sustainable development goal No. 2 Zero Hunger. The sustainability of cricket farming is also discussed in comparison with other livestock. The findings imply that edible crickets are safe for daily intake as a healthy alternative diet due to their high protein content and health-promoting properties. Appropriate use of edible crickets in the food and nutraceutical industries represents a global business potential. However, people who are allergic to shellfish should pay attention on cricket allergy. Thus, the objective of this review was to present in-depth and up-to-date information on edible crickets to advocate and enhance public perception of cricket-based food.

Full textAbstract:
Aversive learning has been studied in a variety of species, such as honey bees, mice, and non-human primates. Since aversive learning has been found in some invertebrates and mammals, it will be interesting to know if this ability is shared with crickets. This paper provides data on aversive learning in male and female house crickets (Acheta domesticus) using a shuttle box apparatus. Crickets are an ideal subject for these experiments due to their well-documented learning abilities in other contexts and their readily quantifiable behaviors. The shuttle box involves a two-compartment shock grid in which a ‘master’ cricket can learn to avoid the shock by moving to specific designated locations, while a paired yoked cricket is shocked regardless of its location and therefore cannot learn. Baseline control crickets were placed in the same device as the experimental crickets but did not receive a shock. Male and female master crickets demonstrated some aversive learning, as indicated by spending more time than expected by chance in the correct (no shock) location during some parts of the experiment, although there was high variability in performance. These results suggest that there is limited evidence that the house crickets in this experiment learned how to avoid the shock. Further research with additional stimuli and other cricket species should be conducted to determine if house crickets and other species of crickets exhibit aversive learning.

In the development of cricket farming, important information in regard with cultivated method, type of crickets, feedstuff, density level, and it’s productivity is essential. The aim of this study was to evaluate the effects of different density level and rations on growth performace of three species of local crickets, i.e Gryllus bimaculatus De Geer, Gryllus mitratus Burn and Gryllus testaceus Walk. Three levels of box square density (500, 750 and 1000 cricket/box) and two levels of additional feed (mustard green and papaya leaves) were used as treatments. The results showed that the density level of approximately 1000 cricket/box had no significant influence on growth performance of the three species local crickets. Nevertheless, higher density level tended to increase mortality rate especially for G. bimaculatus (rate of mortality = 45.86%). The use of feed combination of formulated ration plus mustard green resulted in better growth performance and higher egg production compared to the combination of formulated ration plus papaya leaves.

Over 100 million people in Africa are affected by protein malnutrition because they cannot afford conventional animal protein. The light yellowish-brown cricket (Acheta domesticus) is one of the cricket species preferred for mass rearing. The study was aimed at assessing the safety of the house cricket meal for human and animals’ consumption in Nigeria. Four house crickets were collected from the wild and reared in the animal house of Olabisi Onabanjo University, Ago-Iwoye, Ogun State, Nigeria to produce several generations. Samples of adult and nymph house crickets were obtained from the stock and processed by sun-drying for three days and then analysed for microbial count. Samples of 10 g each were weighed and put in 90 ml of 4% tween 20 in 1 in 10 dilutions. Also, 10 ml was also measured aseptically and transferred to 90 ml of diluent in 1 in 100 bottle. The total aerobic microbial count for adult and nymph house cricket yielded growth with flat opaque colonies of Bacillus sp of 2430 cfu/g and 590cfu/g respectively. The mold count for the adult was 2470 cfu/g and 425 cfu/g for nymph respectively. House crickets sampled were free of diseasecausing microbes such as Escherichia coli, Staphylococcus aureus, Bacillus cereus, Clostridium perfringes and yeast.

Full textAbstract:
Children in Kenya are at risk of undernutrition. Milk powder is the ‘golden standard’ in products to prevent undernutrition but is expensive and cannot be produced locally. House crickets (Acheta domesticus) are rich in nutrients important for growth and development. The cricket biscuit contains protein, unsaturated fatty acids, vitamin A and B12, iron, and zinc. Furthermore, cricket powder can be an economically better substitute for milk powder and can create revenue for the local population. Including crickets in products for school feeding could optimise growth and learning. The objective of the study was to develop a recipe for cricket biscuits suitable for school feeding programmes and test acceptability of the biscuits in Kenyan schoolchildren, in comparison with a similar biscuit with milk. The study was randomised and parallel. Fifty-four children aged 5-10 years were served 100 g (range 98-102 g) biscuits containing either 10% cricket powder or 10% milk powder during school days for four weeks. At baseline anthropometry (weight, height, mid upper arm circumference) was measured and information on insect consumption and allergies collected. Daily, weight of biscuits eaten and hesitation and refusal to eat were noted. Weekly, hedonic ratings were performed. Consumption was 96.9% and 94.2% for cricket and milk biscuits (P=0.14), respectively. Hedonic ratings were significantly lower in cricket biscuits for looks (P=0.006), smell (P=0.04), texture (P=0.02), and overall (P=0.01) compared to milk biscuits, but all ratings were above average (2.5). The biscuits contribute with macro- and micronutrients important for a child in Western Kenya. The acceptability of the cricket biscuits was high and long-term based on set criteria (>75% eaten >75% of the study days). Organoleptic properties were rated above average for cricket biscuits but lower than milk biscuits in most aspects.

Full textAbstract:
Behavioral experiments with crickets show that female crickets respond to male calling songs with syllable rates within a certain bandwidth only. We have made a robot model in which we implement a simple neural controller that is less complex than the controllers traditionally hypothesized for cricket phonotaxis and syllable rate preference. The simple controller, which had been successfully used with a slowed and simplified signal, is here demonstrated to function, using songs with identical parameters to those found in real male cricket song, using an analog electronic model of the peripheral auditory morphology of the female cricket as the sensor. We put the robot under the same experimental conditions as the female crickets, and it responds with phonotaxis to calling songs of real male Gryllus bimaculatus. Further, the robot only responds to songs with syllable rates within a bandwidth similar to the bandwidth found for crickets. By making polar plots of the heading direction of the robot, we obtain behavioral data that can be used in statistical analyses. These analyses show that there are statistically significant differences between the behavioral responses to calling songs with syllable rates within the bandwidth and calling songs with syllable rates outside the bandwidth. This gives the verification that the simple neural control mechanism (together with morphological auditory matched filtering) can account for the syllable rate preference found in female crickets. With our robot system, we can now systematically explore the mechanisms controlling recognition and choice behavior in the female cricket by experimental replication.

The need for mass-production of crickets is increasing with continued awareness. Cricket farming has been introduced with considerable success among small-holder farmers in the warmer, low altitude Lake Victoria regions of Kenya. Efforts are however on-going to introduce the farming in cooler, higher altitude areas in the interest of expanding the enterprise and increase mass production. A pilot farm was established at a farm located 1,519 meters above sea level with a temperature range of 17-22 °C. Initial egg stock was incubated at the farm under room conditions in the month of November to December. Different agricultural side streams and farm weeds were tested as probable cricket feed. Hatch rate, duration of hatching, preferred food types, mortality, weight gain and nutrient content at different ages were assessed. The hatch rate averaged 60%, mortality for hatchlings (pinheads) was below 2% while a steady weight gain was observed over a 12 weeks growth period with highest maximum weight being 2.03 grams per cricket. All agricultural side streams were accepted by the crickets and the wandering Jew weed was among the preferred feed and a source of significant nutrient for the crickets. Protein content ranged from 36-60% while fat content was 12-25%. Cricket production can therefore be promoted in the higher altitude, cooler areas in order to promote industrial exploitation of the crickets in combating food and nutrition insecurity.

Few studies have addressed whether terrestrial insects assess predation risk via chemical cues. We exposed predator-naïve fall field crickets ( Gryllus pennsylvanicus Burmeister, 1838) to filter paper containing the chemical cues of three wolf spiders ( Hogna helluo (Walckenaer, 1837), Rabidosa rabida (Walckenaer, 1837), Rabidosa punctulata (Hentz, 1844)), the house cricket ( Acheta domesticus L., 1758,) and blank filter paper. Crickets exhibited greater immobility and reduced speed of movement when exposed to chemical cues of all three spider species. Crickets exhibited reduced speed with increasing mass of R. punctulata, suggesting that larger spiders may pose a greater risk. Cricket response did not differ between cues of H. helluo fed conspecific crickets versus H. helluo fed house crickets, suggesting that crickets cannot distinguish between cues from H. helluo fed phylogenetically similar crickets. Our work nevertheless demonstrates that naïve field crickets respond to chemical cues of several species of wolf spiders.

The growing population on planet Earth and the deteriorating environment are leading humanity to a swift depletion of resources. And if it is possible to reduce the use of some, it is impossible to eliminate, or even decrease the consumption of protein. Thus, an alternative solution needs to be found. For the past several decades scholars have suggested to breeding crickets as an alternative source of protein. Numerous studies have been made, which resulted in a simple description of the process and a manual of how to establish a breeding cricket farm. However, the fluctuations in breeding conditions stemming from the lack of automation in this sphere, are a hazard to the safe growth and development of the cricket breeding stock. This paper focuses on the developed prototype of a video monitoring equipment developed using machine learning technologies aiming to help identifying hazardous conditions based on the training received in the process of the experiment and numerous tests. The prototype has shown a 70% accuracy rate, yet is capable of determining when the crickets are subjected to various stressors, namely water, nutrition, thermal and methane. Via observing the cricket population, the prototype is learning to alert the breeder as to the potential danger, thereby preserving the cricket population, and increasing the chances of a future mass production of protein from crickets.

Full textAbstract:
The current work is aimed at generating information on giant crickets and the impact of commonly used pesticides on the natural population of these crickets. Data was collected based on interviews and complemented with field observations. Out of 319 respondents surveyed, 290 were aware of the use of the giant cricket as a food source, and 161 were active consumers. Regarding the availability of the giant cricket, respondents reported that the crickets’ populations were diminishing because of farming practices. About 219 persons reported that commonly used herbicides harm giant crickets at different stages. This could be attributed to the scarcity of this species, as mentioned by 233 respondents. The results showed that 130 respondents were engaged in gathering giant crickets for consumption. This insect gathering is related to soil tilling. Chi-square test showed a significant dependence relationship between herbicides use and cricket scarcity. Although less than a majority (129) of respondents are making regular use of persistent pesticides (herbicides), it has been observed that intensive use of pesticides could become a popular practice in smallholder farming categories. This paper thus suggests the need for training and surveillance concerning the trade of pesticides in the region and proposes further investigations into pesticides residues or traces in collected giant crickets consumed in the study site and in all areas with similar conditions.

Crickets are gaining worldwide attention as a nutrient source with a low environmental impact. We considered crickets as a new source of chitin raw material. Chitin isolated from crickets was successfully converted to nanochitin by pulverization. First, chitin was obtained from cricket powder in a 2.6% yield through a series of chemical treatments. Chitin identification was confirmed by FT-IR and 13C NMR. The chitin had an α-type crystal structure and a deacetylation degree of 12%. Next, it was pulverized in a disk mill to obtain nanochitin. Cricket nanochitin was of a whisker shape, with an average fiber width of 10.1 nm. It was larger than that of crab shells, while the hydrodynamic diameter and crystal size were smaller. Such differences in shape affected the physical properties of the dispersion. The transmittance was higher than that of crab nanochitin due to the size effect, and the viscosity was smaller. Moreover, the dry non-woven cricket nanochitin sheets were more densely packed, and their modulus and breaking strength were greater.

The cricket pet food industry in the United States, where as many as 50 million crickets are shipped a week, is a multi-million dollar business that has been devastated by epizootic Acheta domesticus densovirus (AdDNV) outbreaks. Efforts to find an alternative, virus-resistant field cricket species have led to the widespread USA (and European) distribution of a previously unnamed Gryllus species despite existing USA federal regulations to prevent such movement. We analyze and describe this previously unnamed Gryllus and propose additional measures to minimize its potential risk to native fauna and agriculture. Additionally, and more worrisome, is our incidental finding that the naturally widespread African, European, and Asian “black cricket,” G. bimaculatus, is also being sold illegally in southern California pet food stores. We assayed crickets of all five USA and European commercial species for presence of the AdDNV to document extent of the infection—all five species can be infected with the virus but only A. domesticus is killed. Based on its already cosmopolitan distribution, apparent inability to live away from human habitation, and resistance to AdDNV, we suggest that Gryllodes sigillatus is the best-suited replacement cricket for commercial production.

Currently, there is an increased interest in mass producing edible insects, e.g., field crickets (Gryllus bimaculatus), due to their market value and sustainable development. The current study aimed to measure the production performance of field crickets and to quantify the major nutrient deposition rate using a new approach for a nutrient conversion efficiency calculation for the field crickets under mass-rearing conditions. The field crickets were reared under mass-rearing conditions in the rearing crates and fed with a commercial cricket feed. Measurements for daily feed offered, final body weight, and dead cricket quantity were carried out during the feeding trial period. There were three production rounds with the same procedure for farmed cricket management. The samples of diet, adult crickets, and dead crickets were collected and then analyzed for chemical analysis of macronutrients. The production performance and nutrient conversion efficiency were calculated and then compared with applicable earlier reports for both field and house (Acheta domesticus) crickets. The production performance for the studied field crickets under mass-rearing conditions had final a body weight, an average daily gain (ADG), a feed conversion ratio (FCR), and a survival rate of 0.95 g, 23.20 mg/day, 2.94 and 88.51%, respectively. The field crickets had nutrient conversion efficiency for dry matter (DM), ash, crude protein (CP), crude fat (EE), crude fiber (CF), and nitrogen-free extract (NFE) of 13.26, 8.03, 28.95, 88.94, 34.87, and 1.85, respectively, with an adjusted nutrient conversion efficiency of 14.85, 8.99, 32.37, 99.17, 38.95, and 2.10, respectively. Thus, the production of field crickets could be performed under mass-rearing conditions, and the nutrient conversion efficiency for both adjusted and non-adjusted values could be measured.

Since cricket farming was introduced in Thailand in 1997, domestic, regional and international interest in the edible cricket industry has increased. This study aims to identify emerging themes related the development of the edible cricket industry over the past decades. It also discusses additional themes in the development of the cricket industry in connection to the work of other scholars, as well as future considerations to maintain the positive impacts of the industry on rural economic development, entrepreneurship and employment. Eight types of actors in the cricket industry were considered in this study: cricket farmers; wholesale traders and market vendors; tourism agents; international organisa tions; chefs; private companies; researchers; and governmental representatives. The farming and sale of crickets is still a small-scale activity which is relatively profitable for the farmers and other actors in the value chain. Based on the findings of this study, the constraints to growth and further expansion of the industry appear minimal at present. Nonetheless, speculations regarding the positive and negative impacts that further growth may have demonstrate the potential opportunities and threats to the industry. Considering the edible cricket industry as a part of the rural entrepreneurship and development policy discourse may be beneficial to sustainable development.

Considering India only, the changes were not focusing only on the architectural style, but it was the entire process to structure the society in a better way. Britishers, by nature were very fond of recreation, entertainment, luxury in their life. Sports was one of the medium of their entertainment through which they interact among high societies. When cricket was introduced in India by Britishers, it was become most popular game among all the states. Maharajas of princely states were always try to copy the British life style, so they adopted cricket also with full obsession. Maharajas of Patiala, princely state Punjab along with their royal families, were in passionate lead to support Cricket as major sport (Majumdar, B. 2008). They had taken cricket to utmost priority and formed their own cricket grounds in Chail and Patiala. Maharaja Rajinder Singh, constructed a cricket ground and pavilion in 1890 in Patiala named as ‘Dhruve Pandove Stadium’ from where he initiated the cricket patronage (Sarkar, A. 2016). The pavilion is constructed in colonial style, which has given India a number of leading crickets, is still intact in good and working condition.

Full textAbstract:
The demand for house crickets as a source of food or feed is increasing. Meeting this demand will require efficient production systems. House crickets are often fed a combination of dry feed and fresh plant material. Supplying fresh plant material could improve growth and development, but also increases labour and costs. Two experiments were conducted to verify that provision of fresh plant materials has a beneficial effect on house cricket performance. In the first experiment, house crickets were provided with an ad libitum supply of chicken feed, a water dispenser, and with carrots at different frequencies: (1) daily; (2) three times a week; (3) first week daily then three times a week; (4) two weeks daily then three times a week; and (5) no carrots. When the first cricket in a container reached adulthood, all crickets in that container were harvested. Survival, development time and body weight were determined. In a second experiment feed conversion efficiency of house crickets, either provided with carrots daily or not at all, was compared. No effects of carrot provision on survival, development time, body weight or feed conversion efficiency were found. The outcomes of these parameters were similar to other studies in which crickets were provided with chicken feed. The results indicate that supplying carrots in addition to a suitable dry feed and water does not improve house cricket survival, development time, body weight and feed conversion efficiency.

Full textAbstract:
The domesticated house cricket, Acheta domesticus (Linnaeus, 1758), has been lauded as a more sustainable protein source than traditional livestock to meet the ever-increasing demand for food. There is also a potential of using waste food, such as okara (soybean residue from the manufacture of soy milk and tofu) and waste vegetables which are commonly available in many parts of Southeast Asia, to feed these insects. Food wastage can be reduced while increasing the food supply if the crickets can grow and survive well on waste food. Thus, we investigated the viability of rearing A. domesticus on oligidic diets, specifically waste vegetables and okara, to optimise the use of waste food as feed to the crickets. We monitored cricket mortality and fresh weight of 32 individually housed crickets subjected to different diet treatments, every other day for 45 days. The crickets reared on Brassica rapa (xiao bai cai; XBC) and okara mixture did not grow and survive as well as those reared on the XBC and dog food mixture, contradicting our initial prediction that okara is a suitable cricket feed, even though it has been considered one of the best oligidic diets. We also did not find any evidence that crickets reared on mixed diets of XBC and okara food grew or survived better than single diets of XBC or okara. This showed that okara cannot always replace premium animal feed to rear A. domesticus crickets.

Full textAbstract:
The gut microbiome plays an important role in the health of dogs. Both beneficial microbes and overall diversity can be modulated by diet. Fermentable sources of fiber in particular often increase the abundance of beneficial microbes. Banded crickets (Gryllodes sigillatus) contain the fermentable polysaccharides chitin and chitosan. In addition, crickets are an environmentally sustainable protein source. Considering crickets as a potential source of both novel protein and novel fiber for dogs, four diets ranging from 0% to 24% cricket content were fed to determine their effects on healthy dogs’ (n = 32) gut microbiomes. Fecal samples were collected serially at 0, 14, and 29 days, and processed using high-throughput sequencing of 16S rRNA gene PCR amplicons. Microbiomes were generally very similar across all diets at both the phylum and genus level, and alpha and beta diversities did not differ between the various diets at 29 days. A total of 12 ASVs (amplicon sequence variants) from nine genera significantly changed in abundance following the addition of cricket, often in a dose-response fashion with increasing amounts of cricket. A net increase was observed in Catenibacterium, Lachnospiraceae [Ruminococcus], and Faecalitalea, whereas Bacteroides, Faecalibacterium, Lachnospiracaeae NK4A136 group and others decreased in abundance. Similar changes in Catenibacterium and Bacteroides have been associated with gut health benefits in other studies. However, the total magnitude of all changes was small and only a few specific taxa changed in abundance. Overall, we found that diets containing cricket supported the same level of gut microbiome diversity as a standard healthy balanced diet. These results support crickets as a potential healthy, novel food ingredient for dogs.

Full textAbstract:
While Wolbachia, an intracellular bacterial symbiont, is primarily transmitted maternally in arthropods, horizontal transmission between species has been commonly documented. We examined kleptoparasitism as a potential mechanism for Wolbachia horizontal transmission, using ant crickets and their host ants as the model system. We compared prevalence and diversity of Wolbachia across multiple ant cricket species with different degrees of host specificity/integration level. Our analyses revealed at least three cases of inter-ordinal Wolbachia transfer among ant and ant crickets, and also showed that ant cricket species with high host-integration and host-specificity tend to harbor a higher Wolbachia prevalence and diversity than other types of ant crickets. This study provides empirical evidence that distribution of Wolbachia across ant crickets is largely attributable to horizontal transmission, but also elucidates the role of intimate ecological association in successful Wolbachia horizontal transmission.

True crickets belong to the family of the Gryllidae and they can be used not only as food and feed, but also for recreational purposes (fighting or singing). When reared on cheap substrates, they can be used as feed. The house cricket is most often used as human food. The selection of the cricket species may depend on several criteria, such as legislation, resistance to disease, but also taste.

Alternative food sources have become an important focus of research due to increased food demand coupled with reductions in traditional food productivity. In particular, substitutes for protein sources have been of increasing interest due to the unsustainability of traditional protein sources. Insects have been identified as a sustainable alternative to traditional protein sources, as they are easy to produce and contain essential proteins, fats, and minerals. However, mass-rearing insects requires similar considerations as farming traditional protein sources. To increase productively, growth and survival must be maximized at the highest possible densities while minimizing disease and food requirements. Here, we use the house cricket Acheta domesticus, a highly cultivated insect species, to investigate optimal densities for mass rearing at 14 days of age (4th instar). Nymphs were separated into density groups of 0.09, 0.19, 0.47, and 0.93 cricket/cm2 and monitored for growth and survival. Multiple regression revealed sex (p < 0.0001), density (p < 0.0001), and sex*density interaction (p = 0.0345) as predictors of growth rate. Survival to maturation was significantly reduced in both 0.47 (31%) and 0.93 (45%) cricket/cm2 groups compared to the controls. A second experiment was then conducted to investigate the starvation resistance of adult crickets reared from 14 days of age at 0.09, 0.19, 0.93, and 1.86 cricket/cm2. A second multiple regression analysis revealed only density (p < 0.0001) and to a lesser extent sex (p = 0.0005) to be predictors of starvation resistance. These results indicate that mass-rearing house crickets is most optimal at densities < 0.93 cricket/cm2, where impacts on survival and starvation are minimal. Although these results have implications for cricket mass rearing, research on other endpoints, including reproduction and the synergistic effects of other environmental factors, such as temperature and humidity, should be conducted.

Cave crickets are considered as a keystone species that can be used as a cave ecosystem bioindicator. Developing caves as tourism has considerable potential to disturb cave cricket populations. This study aimed to investigate cave cricket population structure and their habitat preference in Sanghyang Kenit cave one year after it developed into a show cave. Data were collected through standardized visual searching in three cave zones: entrance, twilight, and dark. Besides cave crickets, other macroarthropods discovered in each zone were also recorded. Abiotic parameters of habitat comprised air and soil temperatures, RH, soil moisture, soil pH, and light intensity were measured. Data were analyzed to show cave crickets abundance, density, sex ratio, and age structure. Statistical analysis comprising Kruskal Wallis, non-metric multidimensional scaling, and correlation tests were performed. The cave cricket population in Sanghyang Kenit belonged to a single species, Rhaphidophora sp. The population was around 78-108 individuals and distributed in all cave zones. The abundance and density in twilight and dark zones were significantly higher than in the entrance. The number of males outperformed females with a 2.16 ratio. Besides, the population was dominated by the sub-adult class. Environmental parameters of twilight and dark zones tended to be similar to one another compared to the entrance. Cave crickets preferred habitats with dark, humid, and acidic soil pH. Heteropoda sp. and Catagaeus sp. were considered potential predators. This study implies the importance of protecting cave crickets in Sanghyang Kenit.

ABSTRACT Most cricket hindgut microorganisms (60 to 80%) were detected with a universal fluorescent rRNA-targeted probe and found to be eubacteria. Group-specific probes showed that the hindguts of five different cricket species harbor similar bacterial groups, although in different proportions, and that different diets shifted the structure of the hindgut microbial community. The Bacteroides-Prevotellaprobe, of the eight eubacterial probes tested, stained the largest percentage of cells in all crickets.

Full textAbstract:
Background: Physical fitness is a very important aspect of cricket performance with physically prepared cricketers proven to perform better, more consistently, and with fewer injuries. The physical attributes of strength, speed, and endurance enable a cricketer to bat with power over long periods of time, bowl faster, and with greater accuracy, and to field athletically. Aim and Objectives: The present study was aimed to test the physical fitness of cricket players in response to the various tests administered for evaluation of different components of physical fitness. Materials and Methods: It was a cross-sectional analytical study conducted among 65 cricket players of a well-known cricket club in Mumbai. Physical fitness of cricketers was evaluated by measuring various health-related as well as skill-related fitness components. Results: Mean reading of balance in dominant leg of 37.25±9.8 s, while that in non-dominant leg as 21.65±8.9 s. We compared the results using unpaired “t”-test. Static balance of dominant leg is significantly higher as compared to non-dominant leg (P<0.01). Conclusion: The present study will be helpful to recognize level of fitness in each player and accordingly to organize and strengthen the cricket training program, to excel the performance, and also to avoid sport specific injuries in each cricketer.

Full textAbstract:
This article reports findings from a study designed to examine cricket’s role as an international development tool – with a particular focus on how decisions are made at the highest institutional levels to support cricket-related development initiatives. Data for the study are drawn from interviews with executives in the International Cricket Council and the Marylebone Cricket Club who were asked about how and why decision-makers in their organizations chose to engage in development-related work. The study is informed by literature on postcolonialism, sport for development and peace, global politics and the sociology of cricket. The results illustrate that: (a) a select group of executives in the International Cricket Council and the Marylebone Cricket Club make decisions hierarchically, and that decisions reflect organizational mandates; (b) decision-makers tend to be dismissive of critiques of sport for development and peace, with notable exceptions; and (c) the goals and implications of development-related programmes are portrayed differently to different audiences. This article concludes with commentary on the ways that cricket continues to be implicated in postcolonial relationships and on the processes of decision-making in organizations governed by neoliberal policies.

Full textAbstract:
Edible insects are an integrated part of the food sector in many South-East Asian countries. While the majority of studies focus on Thailand and its cricket farming sector, neighbouring countries like Cambodia and Laos also form a regional market for edible insects. The aim of this research was to describe the informal food sector for wild caught crickets in Cambodia. The information was collected in April-May 2012. Information on collection equipment and techniques, processing and trade were obtained from light trap owners, traders, market vendors and governmental representatives. Five cricket species were identified to be the main trade object. Cricket trapping contributed to livelihoods of rural households operating in a self-governing market. As the crickets are caught from the wild, the sustainability of the market has to be questioned. The use of a framework to structure future studies on edible insects in South-East Asia is discussed. Insect trapping and trading is not institutionally anchored as either agriculture or fisheries – or another sector – and provides an interesting case of a food market operating in between the institutionalised sectors.

Bermudagrass (Cynodon sp.) and paspalum (Paspalum vaginatum) genotypes were evaluated in laboratory, greenhouse, and field experiments for potential resistance to the common turfgrass pests, tawny mole cricket (Scapteriscus vicinus Scudder) and southern mole cricket (Scapteriscus borellii Giglio-tos). Potential resistance among 21 seashore paspalums to both insects in an environmental chamber at 27 °C, 85% relative humidity, and 15 hours light/9 hours dark) revealed that Glenn Oaks `Adalayd' was least tolerant of cricket injury, while 561-79, HI-1, and `Excalibur' were most tolerant. Nymphal survival was not influenced by turfgrass type. Plant selections that maintained the highest percentage of their normal growth after 4 weeks of feeding by tawny mole crickets over three separate greenhouse trials were 561-79, HI-1, HI-2, PI-509018, `Excalibur', SIPV-1 paspalums, and `Tifeagle' and `Tifsport' bermudagrasses. Although none of the tested genotypes was highly resistant to tawny mole cricket injury, `TifSport' bermudagrass and 561-79 (Argentine) seashore paspalum were most tolerant.

Full textAbstract:
In addition to feeding on plants, Mormon crickets Anabrus simplex Haldeman, 1852 predate on invertebrates, including one another, which effectively drives their migration. Carnivory derives from lack of dietary protein, with Mormon crickets deprived of protein having less phenoloxidase (PO) available to combat foreign invaders, such as fungal pathogens. Because Mormon crickets commonly occur with grasshoppers that feed on the same plants, we investigated interactions between grasshoppers and Mormon crickets, and hypothesized that if Mormon crickets are predatory on grasshoppers, grasshopper abundance would influence the protein available to Mormon crickets and their immunity. In a field setting, we varied densities of Mormon crickets (0, 10, or 20 per cage) and grasshoppers Melanoplus borealis (0, 15, 30, or 45) in 68 1-m2 cages. After one month, we measured Mormon cricket dietary preferences and PO activity. As predicted, artificial diet consumption shifted away from protein as grasshopper density increased, and immunocompetence, as measured by PO activity, also increased with grasshopper availability. Although nitrogen availability in the vegetation decreased with increasing insect density, predation became an important source of protein for Mormon crickets that enhanced immunity. Grasshoppers can be an important source of dietary protein for Mormon crickets, with prey availability affecting Mormon cricket immunity to diseases.
