Abstract:
The present study evaluated the capacity of Ammophorus rubripes beetles to carry Taenia solium eggs, in terms of duration and viability of eggs in their digestive system. One hundred beetles were distributed into five polyethylene boxes, and then they were infected with T. solium eggs. Gravid proglottids of T. solium were crushed and then mixed with cattle feces. One gram of this mixture was placed in each box for 24 hours, after which each group of beetles was transferred into a new clean box. Then, five beetles were dissected every three days. Time was strongly associated with viability (r=0.89; P<0.001) and the calculated time to cero viability is 36 days. The eggs in the intestinal system of each beetle were counted and tested for viability. Taenia solium eggs were present in the beetle's digestive system for up to 39 days (13th sampling day out of 20), gradually reducing in numbers and viability, which was 0 on day 36 post-infection. Egg viability was around 40% up to day 24 post-infection, with a median number of eggs of 11 per beetle at this time. Dung beetles may potentially contribute towards dispersing T. solium eggs in endemic areas.

Abstract:
AbstractThe predator-predator naïveté hypothesis suggests that non-native predators benefit from being unknown to native predators, resulting in reduced intraguild interference with native predators. This novelty advantage should depend on the ability of native predators to recognize cues of non-native predators. Here, we compared ant aggression and lady beetle reaction in four native and the invasive lady beetle species Harmonia axyridis. In addition, we tested whether lady beetle cuticular hydrocarbons (CHCs) are involved in species recognition, which might explain naïveté if the invasive species has a specific CHC profile. To this end, we conducted behavioral assays confronting two native ant species with both living lady beetles and lady beetle elytra bearing or lacking CHCs of different lady beetle species. Finally, we characterized CHC profiles of the lady beetles using GC–MS. In general, the aggression of Lasius niger was more frequent than that of Myrmica rubra and L. niger aggression was more frequent towards most native lady beetle species compared to H. axyridis. The removal of CHCs from lady beetle elytra reduced aggression of both ant species. If CHCs of respective lady beetle species were added on cue-free elytra, natural strength of L. niger aggression could be restored. CHC analyses revealed a distinct cue composition for each lady beetle species. Our experiments demonstrate that the presence of chemical cues on the surface of lady beetles contribute to the strength of ant aggression against lady beetles. Reduced aggression of L. niger towards H. axyridis and reduced avoidance behavior in H. axyridis compared to the equally voracious C. septempunctata might improve the invasive lady beetle’s access to ant-tended aphids.

Abstract:
The mycobiota of the beetles of the phloem-feeding spruce bark beetle, <i>Ips typographus</i> was studied. The most important group of fungi were the ophiostomatoid fungi. Among them <i>O. penicillatum</i> was very frequent ophiostomatoid species. Other common fungi were <i>O. ainoae, O. bicolor, O. piceaperdum and O. piceae</i>. The ophiostomatoid fungi were often more frequent in beetles collected in galleries than in the beetles caught With a trap. Generally the ophiostomatoid fungi were more ofien isolated from the beetle.s bathed in sterile water for 30 seconds. However <i>C. polonica, O. ainoae</i>, and <i>O. minutum</i> occurred most abundantly in the beetles disinfected in 96% ethyl alcohol for 15 and 30 seconds.

Abstract:
Isolations of Hymenomycetes on a preferential medium were attempted from preflight pine engraver beetles, Ips pini, and the following in-flight bark beetles: pine engraver beetle, I. pini; western pine beetle, Dendroctonus brevicomis; mountain pine beetle, Dendroctonus ponderosae; and red turpentine beetle, Dendroctonus valens. Thirty pine engraver beetles removed from ponderosa pine slash (preflight) yielded no hymenomycete. However, Hymenomycetes were isolated from 50 of 114 beetles (all species) trapped in flight; Fomitopsis pinicola from 44, and other unidentified suspected Hymenomycetes, from 6. Cryptoporus volvatus was not isolated from any of the in-flight beetles. Since most of these isolates were without clamps (monokaryotic), the beetles may acquire basidiospores after emergence from beetle galleries in coniferous trees as hypothesized previously for the Douglas-fir beetle, Dendroctonus pseudotsugae. The isolation of F. pinicola from all species of in-flight bark beetles indicates that these beetles may be important in the dissemination of this hymenomycete.

Abstract:
The ectoparasitic fungusHesperomyces virescensThaxter (Ascomycota: Laboulbeniales) commonly infects the invasive lady beetleHarmonia axyridis(Pallas) and several other aphidophagous lady beetles in North America and Europe. We tested the hypothesis that bodily contact between adults of different lady beetle species supports horizontal transmission ofH. virescens. We used laboratory assays to determine whetherH. axyridisorOlla v-nigrum(Mulsant) harboringH. virescens(i.e., source beetles) transmit the fungus to noninfected target beetlesH. axyridis,O. v-nigrum,Coccinella septempunctataL.,Coleomegilla maculata(De Geer), orHippodamia convergensGuerin-Meneville. Results indicate that intraspecific transmission (i.e., for the source beetlesH. axyridisandO. v-nigrum) was common but interspecific transmission (i.e., from sourceH. axyridisorO. v-nigrumto target species) was low. Interspecific transmission occurred at low rates fromH. axyridisto bothC. septempunctataandO. v-nigrumand fromO. v-nigrumto bothC. septempunctataandH. convergens. Based upon our laboratory assays of forced pairings/groupings of source and target beetles, we predict that horizontal transmission ofH. virescensbetween species of aphidophagous coccinellids is possible but likely rare.

Abstract:
We discovered an auditory sense in a night-flying scarab beetle, Euetheola humilis, the first scarab to be shown to hear airborne sounds. In the field, beetles were captured beneath speakers broadcasting ultrasound that simulated bat echolocation pulses. Apparently, the beetles took evasive action from a potential bat predator and flew into the traps. Using another behavioral assay in laboratory studies, the beetles were sensitive to frequencies ranging from 20 to 70 kHz at levels between 60 and 70 dB SPL. One component of the behavioral response, a head roll, was graded with stimulus intensity, and the number of potentials in electromyographic recordings from muscles involved in the roll increased as stimulus intensity increased. The response latency was about 40 ms at threshold, decreasing to about 30 ms at 20 dB above threshold. The beetle's short response latency is ideally suited for predator avoidance behavior and the frequency tuning of the response suggests that it could function in evasion from insectivorous bats. The beetle's acoustic sensitivity is remarkably similar to that of other night-flying insects showing ultrasound-induced startle and it should provide these scarab beetles with a similar advance warning of predation risk.

Sugiura, Shinji. "Anti-predator defences of a bombardier beetle: is bombing essential for successful escape from frogs?" PeerJ 6 (November 30, 2018): e5942. http://dx.doi.org/10.7717/peerj.5942.

Full text
Abstract:
Some animals, such as the bombardier beetles (Coleoptera: Carabidae: Brachinini), have evolved chemical defences against predators. When attacked, bombardier beetles can discharge noxious chemicals at temperatures of approximately 100 °C from the tip of their abdomens, “bombing” their attackers. Although many studies to date have investigated how bombardier beetles discharge defensive chemicals against predators, relatively little research has examined how predators modify their attacks on bombardier beetles to avoid being bombed. In this study, I observed the black-spotted pond frog Pelophylax nigromaculatus (Anura: Ranidae) attacking the bombardier beetle Pheropsophus jessoensis under laboratory conditions. In Japan, Pe. nigromaculatus is a generalist predator in grasslands where the bombardier beetle frequently occurs. Almost all the frogs (92.9%) observed rejected live bombardier beetles; 67.9% stopped their attacks once their tongues touched the beetles, and 25.0% spat out the beetles immediately after taking the beetles into their mouths. No beetle bombed a frog before being taken into a frog’s mouth. All beetles taken into mouths bombed the frogs. Only 7.1% of the frogs swallowed live bombardier beetles after being bombed in the mouth. When dead beetles were provided instead, 85.7% of the frogs rejected the dead beetles, 71.4% stopped their attacks after their tongues touched the beetles, and 14.3% spat out the beetles. Only 14.3% of the frogs swallowed the dead beetles. The results suggest that the frogs tended to stop their predatory attack before receiving a bombing response from the beetles. Therefore, bombing was not essential for the beetles to successfully defend against the frogs. Using its tongue, Pe. nigromaculatus may be able to rapidly detect a deterrent chemical or physical characteristics of its potential prey Ph. jessoensis and thus avoid injury by stopping its predatory attack before the beetle bombs it.

Abstract:
Tiger beetles are fast diurnal predators capable of chasing prey under closed-loop visual guidance. We investigated this control system using statistical analyses of high-speed digital recordings of beetles chasing a moving prey dummy in a laboratory arena. Correlation analyses reveal that the beetle uses a proportional control law in which the angular position of the prey relative to the beetle's body axis drives the beetle's angular velocity with a delay of about 28 ms. The proportionality coefficient or system gain, 12 s −1 , is just below critical damping. Pursuit simulations using the derived control law predict angular orientation during pursuits with a residual error of about 7°. This is of the same order of magnitude as the oscillation imposed by the beetle's alternating tripod gait, which was not factored into the control law. The system delay of 28 ms equals a half-stride period, i.e. the time between the touch down of alternating tripods. Based on these results, we propose a physical interpretation of the observed control law: to turn towards its prey, the beetle on average exerts a sideways force proportional to the angular position of the prey measured a half-stride earlier.

Abstract:
AbstractWe used pitfall trapping to measure the species richness and relative abundance of ground beetles (Coleoptera: Carabidae) in four forest habitats on Kent Island, a 80-ha island in the Bay of Fundy, New Brunswick, Canada. Sixteen species of ground beetles representing 11 genera were identified in the forested habitats on Kent Island; the relative paucity of ground beetle species may be a result of the island’s harsh climate, dense colonies of breeding seabirds, and isolation from the mainland. Estimates of ground beetle population densities on Kent Island ranged from 50 000 to 250 000/ha. Most ground beetle species were trapped in all habitats and appeared to be habitat generalists. In a series of experiments in which we removed all ground beetles trapped daily over a 3-week period in two experimental plots, ground beetle densities remained as high as in a control plot; other ground beetles quickly moved into the experimental plots to replace beetles that had been removed. The density of ground beetles was highest in intact forest and large forest patches; in contrast, the density of invertebrates other than ground beetles (i.e., possible prey or competitors of ground beetles) was highest in open habitats and isolated forest patches, where ground beetles were less common. Removing ground beetles from experimental plots did not result in an increase in the density of other invertebrates.

Abstract:
Seasonal abundance and activity period blister beetle (Mylabrispustulata) on pigeonpea and mungbean were recorded at Research Farms of Pulses Section, Department of Plant Breeding and Genetics, Punjab Agricultural University, Ludhiana. The results showed that the blister beetle started appearing in pigeonpea and mungbean in late August under Punjab conditions. During the crop season, its activity increased and reached at its peak in the end of September (13.90 beetles / 4 meter row length in pigeonpea and 5.48 beetles / 1 sq. meter quadrate in mungbean) coincided with the maximum flowering and afterwards it started declining due to the termination of flowers. The activity of blister beetle was more in the morning (20.23 beetles / 4 meter row length in pigeonpea and 8.04 beetles / 1 sq. meter quadrate in mungbean) and evening hours (21.04 beetles / 4 meter row length in pigeonpea and 8.06 beetles / 1 sq. meter quadrate in mungbean) as compared to the noon hours (0.43 beetles / 4 meter row length in pigeonpea and 0.33 beetles / 1 sq. meter quadrate in mungbean).

Pine bark beetles in Arizona are generally of the genus Ips or Dendroctonus. Fading foliage in the tree is often the first sign of a beetle attack. Prevention is best practiced since control is not possible once the beetles have successfully colonized the tree. Colonization is dependent upon trees being in a vulnerable condition caused by stress from various agents and site conditions.

Cypress bark beetles are native insects that often impact ornamental Arizona cypress and Leyland cypress trees. Healthy, vigorous cypress trees can usually withstand substantial beetle pressure. However, significant mortality of host tree species often occurs during periods of extended drought. Tree vigor can easily be maintained through deep, infrequent irrigation during drought periods.

Abstract:
Phellopsis LeConte is revised. Phellopsis porcata (LeConte) is returned to valid status and P. yulongensis NEW SPECIES is described. Phellopsis montana Casey NEW SYNONYMY (NS) and P. robustula Casey NS = P. porcata (LeConte). Phellopsis imurai Masumoto = P. amurensis (Heyden) NS. Species redescriptions, a key to species and notes on the history, biology and biogeography of the group are provided. Phylogenetic analyses support several changes to sustain monophyletic genera of Zopherini because the genera Meralius Casey, Nosoderma Solier, and Phloeodes LeConte were found to be polyphyletic. The genus Sesaspis Casey NEW STATUS is re-recognized, and redescribed to include the following species: Sesaspis denticulata (Solier), S. emarginatus (Horn) NEW COMBIATION (NC), S. lutosus (Champion) NC, S. doyeni (García-París et al.) NC, S. adami NEW SPECIES, S. ashei NEW SPECIES, and S. triplehorni NEW SPECIES. Phloeodes LeConte is clarified with 10 new synonymies [P. diabolicus (LeConte) = P. pustulosus (LeConte) NS, P. latipennis Casey NS, P. ovipennis Casey NS, P. elongatus Casey NS, P. scaber Casey NS, P. angustus Casey NS, and P. remotus Casey NS). Phloeodes plicatus (LeConte) = Noserus torvus Casey NS, Noserus collaris Casey NS, Noserus corrosus Casey NS, Noserus convexulus Casey NS]. Phloeodes venustus (Champion) NC is supported as a member of this clade extending the known range of the genus into Central America. Noserinus furcatus (Kirsch) NC is moved from Meralius Casey. Meralius clavapilus NEW SPECIES is described from Venezuela. Eleven new synonyms are proposed in Nosoderma Solier (N. championi Casey NS, N. prominens Casey NS, N. senex Casey NS, N. brevicolle Casey NS, and N. subglabrum Casey NS = N. inaequalis (Say); N. interruptum Champion NS = N. insigne Champion; N. carinatum Champion NS, N. anceps Champion NS, N. impressum Champion NS, and N. longipennis Casey NS = N. exsculptum Champion; and N. squalidus Casey NS = N. guatemalensis Champion). Scoriaderma congolense Fairmaire NS is a junior synonym of Nosoderma scabrosum Solier. Keys to the genera of Zopherini and species of Meralius Casey, Noserinus Casey, Nosoderma Solier, Phloeodes LeConte and Sesaspis Casey are provided, with illustrations of all included species of the genera mentioned.

Bibliography: leaves 95-104.
Beetles pollinate over 80% of all flowering plants and feed on the two most common floral rewards, nectar and pollen. Pollen is nutritionally very valuable, being a rich protein and carbohydrate source. However, the hard and highly resistant outer wall (exine) of the grain is an obstacle that pollen-feeders must overcome in order to benefit from the pollen's nutritious protoplasm. There are a variety of mechanisms that pollen-feeders may use to deal with the exine. Collembolans secrete exinase that breaks down the wall, but other pollen-feeders do not produce this enzyme. Pollen-feeders that are unable to ingest grains may either pierce the grain and suck out the contents (thrips and biting-flies) or cause the grain contents to leach out an imbibe the leachate (butterflies and the eucalupt nectar fly). Pollen-feeders that can ingest the grains (bees, syrphid flies, rodents, marsupials, bats and birds) may use osmotic shock, pseudo-germination, exudation, microbial digestion or enzyme penetration to gain access to the protoplasmic contents. Further study is needed to define the details of these methods and whether they are all in use.

Abstract:
AbstractBark beetles often feed on dead or dying plant tissues, serving as primary decomposers. However, some bark beetle species kill healthy trees, although at the time of attack, these healthy trees are often experiencing stressful conditions, such as drought or lightning strikes. Populations of tree-killing bark beetles can increase in size to a level where they can overcome the resistance of healthy trees and cause mass destruction of forests resulting in tremendous economic and ecological damage. This chapter introduces the reader to bark beetle natural history, diversity, evolution and management. Natural history is organized by feeding ecology, mating strategies, and intra– and interspecific interactions. Evolution and diversity of bark beetles includes discussion of phylogeny, timing of evolutionary events and an annotated and illustrated list of bark beetle genera important to forest entomologists. Management and control covers efforts to reduce losses to bark beetle destruction of forests and plant products. Finally, we present case studies, including outbreak events, which have resulted in vast economic and ecological loss.

AbstractThe term “ambrosia beetles” refers to an ecological strategy shared by thousands of species of wood-boring weevils from multiple lineages, rather than a single taxonomic group. Most ambrosia beetle groups evolved from within the bark battles (Curculionidae; Scolytinae), which are a diverse group of weevils which bore into trees and whose progeny develop by feeding on the host tree tissue.

Abstract:
It is commonly known that vibrations and acoustic oscillations can cause both negative and positive influence on living organisms. The most harmful effect is caused by the tone acoustic oscillations when the tone frequency coincides with the resonance frequency of the whole body or individual organs. Hence, it is possible to make a conclusion that there are prerequisites for creation acoustic method having harmful or even mortal effect on the Colorado beetle organism. The subjects of the experiment were 8 beetles with the mass of 100 – 200mg. The frequency of the oscillation effect was 500–2500Hz. Examinations of the beetle after 6 hours showed that the biological death did take place. The repeated examination of the beetles after 24 hours showed the biological death of all the beetles exposed to acoustic influence. Using the described experiment, the resonance frequency for the beetle’s body was determined. So, it is possible to eliminate the Colorado beetle by exposing to vibration and acoustic oscillation. It is necessary to know the data relating to the mass of a beetle and its stiffness. Also, a question about the frequency band of the exposure arises. The resonance frequency of the body as a viscoelastic system is determined. The authors carry out experiments and determinate the mass and the stiffness of the Colorado beetle body. On the basis of the data of the outer inspection the biological death is registered for the beetle of the mass 100mg after the influence of the 1500Hz frequency vibration noise level was 120dB. On the basis of these data the stiffness of the Colorado beetle body is estimated as 8,860 N/m.

Abstract:
In field practice on invertebrate zoology and other subjects, in addition to the traditional methods of collecting insects, we can use pheromone traps. Traps were applied in studying the dynamics of xylophilous insects: a sawyer beetle and two bark beetles (an eight-dentated bark beetle and a six-dentated bark beetle). The pheromonitoring have been obtained seasonal variations in the number of populations and density of these species of some nature conservation area in Karelia. The collection efficiency of bark beetles during the period of the maximum number of species was about 600 individuals.

Abstract:
This study primarily proposes a procedure to design a crease pattern for beetle-inspired deployable wings based on the hindwings in relatively large-sized beetles like horn beetle or chafer. First, we discuss the representative patterns of wing supports and crease lines based on previous entomological research and propose a basic geometry for the artificial wing. Next, the flat foldability and rigid foldability of the proposed crease pattern are discussed based on origami geometry. Geometrical restrictions for flat- and rigid-foldable wings are numerically expressed as a function of the design parameters, and the Newton-Raphson method is used to compute the actual solutions. Although researchers have attempted to characterize the representative crease patterns found in beetles, only flat foldability has been considered in previous research. Our proposed method enables the design of rigid-foldable wings based on beetle-inspired patterns, which is considered beneficial in designing the deployable structures.

Abstract:
Abstract This paper describes the mechanical design of a walking machine that avoids overconstraint. All current walking machines that are also capable of standing on their own are overconstrained and must depend on force control algorithms to control joints. From observations of darkling beetles we have concluded that it is possible for them to perambulate while keeping their bodies constrained but not overconstrained. Our walking machine was built to test hypotheses of how these beetles walk. We discuss the aspects of beetle leg kinematics that are most important for non-overconstrained walking.

Abstract:
Foldable hindwings in beetles are one of the ultimate deployable structures. They have sufficient strength and stiffness to tolerate 20–1000 beats per second in the flight position, although they can be folded and unfolded nearly instantly depending on the situation. This study focuses on a group of beetles that have unfolding-stable-type wings and aims to reveal their wing-folding/unfolding mechanisms. These beetles use their wing elasticity for deployment and can therefore quickly take off. First, on the basis of the reports of entomologists, the authors describe the factors related to the actuation of insect wing folding and unfolding. Then, the detailed motions involved in take-off and wing storing in ladybird beetles and rove beetles are observed by a high-speed camera. The analysis of these movies reveals the detailed processes of wing-unfolding and folding in these two species. Intrinsic elasticity plays a major role in wing development in both species. In the case of wing storing, a ladybird beetle folds its hindwings into a symmetric pattern using a simple up–down movement of the abdomen, whereas rove beetles also use their abdomens for wing-folding, but their movements are more complex, and the crease patterns are asymmetric. Finally, the characteristics of each wing-folding mechanism are summarized and the potential for engineering applications are discussed. Wing-folding/unfolding mechanisms in these insects have various unique capabilities which will provide new possibilities for designing deployable structures.

Abstract:
A pitfall survey of beetles in steppe ecosystems of the Republic of Moldova was conducted. Five locations were investigated, two from the Balti steppe and three from the Bugeac steppe. As a result, a total of 563 beetle specimens, belonging to 98 species, 51 genera, and 15 families were collected. Among families recorded Carabidae was the one with the highest number of species. The ecological features of collected beetle species were revealed. The results show that steppes are still important biodiversity reservoirs within the boundaries of the country and urgent conservation activities are required.

Full text
Abstract:
Bark beetles, particularly those in the genus Ips, are major pests of conifer trees in Europe, causing extensive damage to both natural and commercial forests. The ECLIPSE project has analyzed the history of Ips infestations, focusing on factors driving their geographic spread. Key findings indicated that the availability of suitable host trees, largely due to extensive afforestation with conifers, was a primary factor enabling beetle infestations. Climatic factors, such as extreme weather events, further exacerbated infestations by weakening trees. Long-distance dispersal through both beetle flight and human movement of infested wood contributed to the spread. The project also highlighted the importance of monitoring beetle arrivals and source populations to manage risks effectively. Policy recommendations emphasized the need for integrated pest risk assessments that consider both natural dispersal and trade-related movements. The obtained results underscored the necessity of international collaboration and timely information sharing to mitigate the impact of bark beetle infestations.

Abstract:
Saperda candida (Coleoptera: Cerambycidae) is native to the eastern USA and southeastern Canada. It was detected in Germany in 2008, where eradication efforts were undertaken. This beetle primarily infests woody hosts within the Rosaceae family, with Cydonia, Malus and Pyrus being significant cultivated hosts in North America. The larvae cause severe damage by girdling the trunks of young trees, leading to tree death. Improved pest management in the mid-20th century reduced its impact in orchards. Despite being an EPPO A1 Pest and an EU A1 quarantine pest, no classical biological control has been attempted. Potential natural enemies include 5 hymenopterous parasites (Cenocoelius saperdae, Echthrus niger, Monogonogastra agrili, Xylophrurus nubilipennis luctuosus and Sarcophaga sp.), which are not present in the EPPO region. Additional predators such as spiders, ants, click beetles, carabid beetles and several woodpecker species also contribute to natural control.

Full text
Abstract:
Toward development of spiroplasmas as novel toxin-delivery systems for biocontrol of beetle pests in the United States (Leptinotarsa decemlineata) and Israel (Maladera matrida), media for cultivating beetle-associated spiroplasmas were improved and surveys of these spiroplasmas were conducted to provide transformable strains. Extensive surveys of spiroplasmas yielded promising extrachromosomal elements for vector constructs. One, plasmid pCT-1, was cloned, characterized, and used as a source of spiroplasma origin of replication in our shuttle vectors. The fibrillin gene was isolated and sequenced and its strong promoter was also used in the constructs. Means for transforming these vectors into spiroplasmas were developed and optimized, with electroporation found to be suitable for most applications. Development and optimization of means for using large unilamellar vesicles (LUVs) in spiroplasma transformation represents a breakthrough that should facilitate insertion of large clusters of virulence genes. With completion of the vector, we should thus be poised to genetically engineer spiroplasmas with genes that will express toxins lethal to our target beetles, thus providing an effective and inexpensive alternative to conventional means of beetle control.
