Abstract:

In the face of mosquito-borne disease outbreaks, effective mosquito control is a primary goal for public health. Insect repellents, containing active compounds such as DEET and picaridin, are a first defence against biting insects. Owing to widespread use and incomplete sewage treatment, these compounds are frequently detected in surface waters, but their effects on aquatic taxa such as mosquito larvae or their naturally occurring aquatic predators are poorly understood. We investigated the effects of environmentally realistic concentrations of commercial products containing DEET and picaridin on survivorship of mosquito larvae, and their potential indirect effects on survival of larval salamanders, a major predator of mosquito larvae. Larval mosquitos were not affected by exposure to repellents containing DEET or picaridin. We found no larval salamander mortality in control and DEET treatments, but mortality rates in picaridin treatments ranged from 45 to 65% after 25 days of exposure. Salamander larvae exposed to repellents containing picaridin began to display tail deformities and impaired development four days after the experiment began. Our findings suggest the possibility that environmentally realistic concentrations of picaridin-containing repellents in surface waters may increase the abundance of adult mosquitos owing to decreased predation pressure.

Abstract:

Abstract Entomopathogenic nematodes (EPNs) are widely used agents of biological control, mainly targeting soil-inhabiting insect pests. Reports indicate that these terrestrial EPNs are also able to infect the aquatic larvae of mosquitoes. We isolated EPN strains (Heterorhabditis bacteriophora Poinar and Steinernema carpocapsae [Weiser]) from local soils at Saltillo, Coahuila state, Mexico. EPNs from these strains were produced in the laboratory in yellow mealworm (Tenebrio molitor L.) larvae, and their pathogenicity as infective juveniles (IJs) was tested against larvae of the yellow fever mosquito Aedes aegypti (L.) Third- and fourth-instar mosquito larvae were exposed to four concentrations of IJs (25, 50, 100, and 200 IJ/larva) of five strains of local EPNs in laboratory assays. All strains of EPN caused lethal infections in larvae (3–100%); in particular, strain M5 of S. carpocapsae caused 100% mortality at the 200 IJ/larva concentration, with a median lethal concentration (LC50) of 42 IJ/larva (LC90 = 91 IJ/larva). Strain M18 of H. bacteriophora caused 73% mortality at 200 IJ/larva, with an LC50 = 72 and LC90 = 319 IJ/larva. IJs were produced by all strains in mosquito larvae, with a range of 66–239 IJ/mosquito larva (inoculated at 100 IJ/larva) across strains, suggesting that horizontal transmission might occur in the field. This represents the first report of native EPN strains from Mexico exhibiting pathogenicity against mosquito larvae. Native EPN strains should be further evaluated as potential biological control agents in mosquito management.

Abstract:

Mosquitoes are prolific disease vectors that affect public health around the world. Although many studies have investigated search strategies used by host-seeking adult mosquitoes, little is known about larval search behaviour. Larval behaviour affects adult body size and fecundity, and thus the capacity of individual mosquitoes to find hosts and transmit disease. Understanding vector survival at all life stages is crucial for improving disease control. In this study, we use experimental and computational methods to investigate the chemical ecology and search behaviour of Aedes aegypti mosquito larvae. We first show that larvae do not respond to several olfactory cues used by adult Ae. aegypti to assess larval habitat quality, but perceive microbial RNA as a potent foraging attractant. Second, we demonstrate that Ae. aegypti larvae use chemokinesis, an unusual search strategy, to navigate chemical gradients. Finally, we use computational modelling to demonstrate that larvae respond to starvation pressure by optimizing exploration behaviour—possibly critical for exploiting limited larval habitat types. Our results identify key characteristics of foraging behaviour in an important disease vector mosquito. In addition to implications for better understanding and control of disease vectors, this work establishes mosquito larvae as a tractable model for chemosensory behaviour and navigation.

Abstract:

This study describes the aquatic habitats, species composition, and the insecticide resistance level of the mosquito Culex pipiens pallens in Shandong Province, China. A cross-sectional survey of mosquito larval habitats was conducted from May to November 2014 to determine the species composition and larval abundance. Larvae were collected using the standard dipping technique, and a total of four habitat types were sampled. The fourth instar larvae of Cx. pipiens pallens collected in each habitat type were tested for resistance to five insecticides according to a WHO bioassay. A total of 7,281 mosquito larvae were collected, of which 399 (5.48%) were categorized as Anopheles mosquito larvae ( An. sinensis), 6636 (91.14%) as culicine larvae ( Cx. pipiens pallens, Cx. tritaeniorhynchus, Cx. halifaxii, and Cx. bitaeniorhynchus), 213 (2.93%) as Armigeres larvae, and 33 (0.45%) as Aedes larvae ( Aedes albopictus). In addition, a total of 1,149 mosquito pupae were collected. Culex larvae were distributed in all habitats investigated. Tukeys HSD analysis showed that roadside drainages were the most productive habitat type for Culex larvae. Armigeres species were found only in drains, Aedes only in water tanks, and Anopheles in water that was comparatively clear and rich in emergent plants. Bioassay showed that the maximum resistance level of Cx. pipiens pallens was to deltamethrin, while it was lowest to plifenate. The productivity of various mosquitoes in different habitat types is very heterogeneous. It is particularly important to modify human activity and the environment to achieve effective mosquito vector control. For effective larval control, the type of habitat should be considered, and the most productive habitat type should be given priority in mosquito abatement programs.

Abstract:

Biological control of mosquitoes can have unintended ecological consequences. One example is the introduction of the genus Gambusia Poey, 1854 into ponds and wetlands. Gambusia spp. are invasive in many parts of the world and have the potential to alter ecosystems by changing trophic interactions and extirpating amphibians. We sought to determine whether larval amphibians are capable of consuming larval mosquitoes as effectively as Gambusia spp. We tested the predation ability of larval Spotted Salamanders (Ambystoma maculatum (Shaw, 1802); n = 13), Southern Leopard Frog (Rana sphenocephala Cope, 1886; n = 12) tadpoles, and western mosquitofish (Gambusia affinis (Baird and Girard, 1853); n = 13) across a range of body sizes in laboratory experiments. Our results showed that over a 24 h period, salamander larvae (mean ± SE; 238 ± 14) and mosquitofish (195 ± 17) consumed a statistically equivalent number of mosquito larvae, whereas tadpoles consumed a large number (113 ± 14) but significantly less. All species had significant (or marginally significant) positive relationships between body size and rate of mosquito consumption. Further studies into the ability of native larval amphibians to consume mosquito larvae are needed to assess whether amphibians can be successful at mosquito control instead of introducing nonnative species to new areas.

Abstract:

Mosquitoes have been a nuisance and health threat to humans for centuries due to their ability to transmit different infectious diseases. Biological control methods have emerged as an alternative or complementary approach to contain vector populations in light of the current spread of insecticide resistance in mosquitoes. Thus, this study aimed to evaluate the predation efficacy of selected potential predators against Anopheles mosquito larvae. Potential invertebrate predators and Anopheles larvae were collected from natural habitats, mainly (temporary) wetlands and ponds in southwest Ethiopia and experiments were conducted under laboratory conditions. Optimal predation conditions with respect to larval instar, water volume and number of predators were determined for each of the seven studied predators. Data analyses were carried out using the Poisson regression model using one way ANOVA at the 5% significant level. The backswimmer (Notonectidae) was the most aggressive predator on Anopheles mosquito larvae with a daily mean predation of 71.5 larvae (95% CI: [65.04;78.59]). Our study shows that larval instar, water volume and number of predators have a significant effect on each predator, except for dragonflies (Libellulidae), with regard to the preference of the larval instar. A selection of mosquito predators has the potential to control Anopheles mosquito larvae, suggesting that they can be used as complementary approach in an integrated malaria vector control strategy.

Abstract:

For organisms with complex life cycles, larval environments can modify adult phenotypes. For mosquitoes and other vectors, when physiological impacts of stressors acting on larvae carry over into the adult stage they may interact with infectious dose of a vector-borne pathogen, producing a range of phenotypes for vector potential. Investigation of impacts of a common source of stress, larval crowding and intraspecific competition, on adult vector interactions with pathogens may increase our understanding of the dynamics of pathogen transmission by mosquito vectors. Using Aedes aegypti and the nematode parasite Brugia pahangi , we demonstrate dose dependency of fitness effects of B. pahangi infection on the mosquito, as well as interactions between competitive stress among larvae and infectious dose for resulting adults that affect the physiological and functional ability of mosquitoes to act as vectors. Contrary to results from studies on mosquito–arbovirus interactions, our results suggest that adults from crowded larvae may limit infection better than do adults from uncrowded controls, and that mosquitoes from high-quality larval environments are more physiologically and functionally capable vectors of B. pahangi . Our results provide another example of how the larval environment can have profound effects on vector potential of resulting adults.

Abstract:

Quite a number of diseases are transmitted by mosquitoes. The abundance and distribution of mosquito vectors are related to the characteristics of larval habitats. A survey of the distribution and abundance of mosquito larvae was carried out at Nkporo and Abiriba Communities of Ohafia, Abia State, Nigeria. It was carried out during the dry and wet seasons from November 2014 to June 2015. The mosquito larvae were collected using dipper and pipette method from five mosquito habitats namely ground pools (58), household containers (213), domestic run-offs (49), gutters (55) and tree holes/leaf axils (43). A total of 2 641 mosquito larvae belonging to three genera and five species were collected. These were; Culex quinquesfaciatus (40%),Aedes aegypti (22%), Aedes albopictus (17%), Anopheles gambiae (14%), and Anopheles funestus (2%), Household containers had the highest number of larvae (60 %), while tree holes/leaf axils had the least (6%). From Nkporo, 53% of the larvae were collected while 47% was from Abiriba community. Anopheles funestus was recorded only in Nkporo community. However, the abundance of mosquito larvae sampled from the different habitats in the two communities were significantly different (X2 = 166,692, df = 16, P<0,05) from each other. There were also significant differences in the seasonal distribution of mosquito larvae in both dry (X2 = 56,865, df = 12, P<0,05) and wet (X2 = 22,241, df = 12, P<0,05) seasons in Nkporo community and dry (X2=31,776, df = 12, P<0,05) season in Abiriba community. These findings are useful in knowledge expansion on the vector ecology with particular interest on the type of habitat preference, this will be helpful in larval control programs.

Abstract:

Among the natural predators, larval stages of the mosquito <em>Lutzia fuscana (</em>Wiedemann, 1820) (Diptera: Culicidae) bear potential as a biological control agent of mosquitoes. An estimation of the predatory potential of the larva of <em>L. fuscana</em> against the larva of the dengue vector <em>Aedes aegypti</em> (Linnaeus, 1762) (Diptera: Culicidae) was made to highlight its use in vector management. Laboratory experiments revealed that the larva of<em> L</em>. <em>fuscana</em> consumes 19 to 24 <em>A. aegypti</em> larvae per day, during its tenure as IV instar larva. The consumption of <em>A. aegypti</em> larvae was proportionate to the body length (BL) and body weight (BW) of the predatory larva<em> L. fuscana</em> as depicted through the logistic regressions: y = 1 / (1 + exp(-(-2.09 + 0.35*BL))) and y = 1 / (1 + exp(-(0.4+ 0.06*BW))). While the prey consumption remained comparable among the days, the net weight gained by the <em>L</em>. <em>fuscana</em> larva showed a decreasing trend with the age. On the basis of the results, it is apparent that the larva of the mosquito <em>L. fuscana</em> can be used in the regulation of the mosquito <em>A. aegypti</em> through augmentative release, particularly, in the smaller mosquito larval habitats.

Abstract:

Immature mosquitoes are aquatic, and their distribution, abundance, and individual fitness in a particular breeding habitat are known to be dependent on mainly three factors: biotic factors, abiotic factors, and their interaction between each other and with other associated taxa. Mosquito breeding habitats harbor a diversified naturally occurring microbiota assemblage, and the biota have different types of interactions with mosquito larvae in those habitats. Those interactions may include parasitism, pathogenism, predation, and competition which cause the mortality of larvae, natural reduction of larval abundance, or alterations in their growth. Many microbiota species serve as food items for mosquito larvae, and there are also some indigestible or toxic phytoplanktons to larvae. However, when there is coexistence or mutualism of different mosquito species along with associated microbiota, they form a community sharing the habitat requirements. With the available literature, it is evident that the abundance of mosquito larvae is related to the densities of associated microbiota and their composition in that particular breeding habitat. Potential antagonist microbiota which are naturally occurring in mosquito breeding habitats could be used in integrated vector control approaches, and this method rises as an ecofriendly approach in controlling larvae in natural habitats themselves. To date, this aspect has received less attention; only a limited number of species of microbiota inhabiting mosquito breeding habitats have been recorded, and detailed studies on microbiota assemblage in relation to diverse vector mosquito breeding habitats and their association with mosquito larvae are few. Therefore, future studies on this important ecological aspect are encouraged. Such studies may help to identify field characteristic agents that can serve as mosquito controlling candidates in their natural habitats themselves.

Abstract:

Malaria is a widespread parasitic disease in developing countries of the tropics and subtropics, infecting approximately 200 million people and causing over half a million deaths every year. The disease is caused by the protozoan Plasmodium and is transferred to humans through infective bites from female mosquitoes of the genus Anopheles. In order to reduce malaria transmission, measures of larval control have been implemented throughout the tropics. This includes usage of larvicides, source reduction by environmental or physiochemical manipulation as well elimination of larval habitats. The purpose of this study was to evaluate differences in occurrence and densities of anopheline larvae by investigating the environmental characteristics of their habitat. The study was conducted in the Gamo Gofa Zone, Great Rift Valley, Ethiopia where a total of 26 sampling sites were chosen for larval sampling. Each sampling site was characterized according to a protocol and sampled for water chemistry analysis. Environmental variables studied include water depth, habitat size, distance to nearest dwelling, land use within a 10 m and 100 m from the sampling site and number of domestic animals within a 100 m. Physiochemical variables include water temperature, pH, electric conductivity (EC), total dissolved solids (TDS), dissolved oxygen (DO), turbidity and phosphate. Larval sampling was conducted on each site using a soup ladle dipper. The occurrence of anopheline larvae was statistically analysed using multiple logistic regressions, while using linear regression for analysing larval abundance at positive sites. Larval sampling resulted in a total of 1245 mosquito larvae, 567 anopheline and 678 non-anopheline. Of the anopheline larvae, 118 were analysed morphologically by microscopy which resulted in 117 belonging to An. gambiae complex and one An. garnhami. Of the 26 sites investigated, 16 were positive for anopheline larvae. All sampled river fringes and flood pools were positive for anopheline larvae whereas none were found in irrigation channels. Negative correlation for anopheline larval occurrence was obtained for both water depth and percentage of tall vegetation within 10 m radius of the sampling area. Anopheline larval abundance was only correlated, positively, with water temperature. The study concludes that water depth, temperature and percentage of tall riparian vegetation are important factors to consider when designing a control program for anopheline larvae. One should be aware of the fact that clearing riparian forest and other tall vegetation is likely to improve growing conditions for anopheline larvae. Furthermore, different habitat classes were either exclusively positive or negative for anopheline larvae, irrigation channels in the area not being suitable larval habitats during the time of measurements. The authors suggest that more studies are needed, preferably on a larger set of sampling sites and over a longer period.

Abstract:

Some Bacillus sphaericus strains (e.g. IAB59, LP1G and 47-6B) can overcome resistance in Culex mosquito larvae, raised against the well characterised binary toxin from this bacterium. A common spore protein (P49), of approximately 49 kDa, produced by these strains has previously been proposed to be responsible for this toxicity. Protein fingerprint analysis of sporulated cultures of these strains identified a number of candidate toxins. Their N-terminal sequences were determined and used to design degenerate oligonucleotide probes. Southern blotting, cloning and colony hybridisation allowed the identification of clones containing genes encoding the putative toxins Cry49Aal (P49) and Cry48Aal (P135) from IAB59. The 1,395 bp cry49Aal gene encodes a protein of 53.3 kDa, showing homology to BinA and BinB from B. sphaericus as well as Cry36Aal and the Cry35 binary toxins from Bacillus thuringiensis. The 3,534 bp cry48Aal gene encodes a 135.6 kDa protein showing homology to the three-domain Cry toxins from B. thuringiensis, including the mosquitocidal Cry4Aa and Cry4Ba from B. thuringiensis subsp. israelensis. Individual expression of these proteins in an acrystalliferous B. thuringiensis subsp. israelensis strain, followed by bioassays against mosquito larvae revealed no toxicity. However, a Cry48Aal/Cry49Aal combination was toxic to both Bin-susceptible and Bin-resistant Culex quinquefasciatus larvae. Aedes aegypti and Anopheles gambiae mosquito larvae were insensitive to the combination, as were a range of other dipteran, coleopteran and lepidopteran insects. The components of this novel binary toxin from B. sphaericus are highly conserved among strains able to overcome resistance. Differential processing of Cry48Aal by C. quinquefasciatus and A. aegypti larval gut proteinases is not responsible for the non-toxicity towards the latter mosquito. Cry49Aal and Cry48Aal form bipyramidal and amorphous crystals respectively at sporulation and their expression involves RNA polymerase factor cr6 in B. subtilis. Discovery of Cry49Aal and Cry48Aal may prove central in the development of strategies to avoid resistance development against B. sphaericus in Culex populations.

Abstract:

Chaoborus americanus larvae were used in laboratory experiments to assess their efficiency at decreasing mosquito larval populations. Third and fourth instar Chaoborus americanus larvae were independently fed assemblages of single prey species to test hunger and several prey species to test preference. Prey species included Daphnia and the four Aedes aegypti larval instars. The results show that Chaoborus americanus larvae will choose early instar mosquito larvae over Daphnia, however, this preference decreases as the mosquito larvae become older. Third instar Chaoborus americanus larvae will choose first instar mosquito larvae over Daphnia 76% of the time, whereas they will select third instar mosquito larvae only 30% of the time. Fourth instar Chaoborus americanus larvae will choose first instar mosquito larvae 94% of the time, and select fourth instar mosquito larvae only 3% of the time. Crowding also has an effect on feeding times; individual Chaoborus larvae take more time to ingest their prey items than do individuals within a group. Chaoborus americanus larvae are good biological control agents within a laboratory setting.

Abstract:

Rift Valley fever (RVF) is an acute disease of domestic ruminants in mainland Africa and Madagascar, caused by a mosquito borne virus and characterized by necrotic hepatitis and a haemorrhagic state. Large outbreaks of the disease in sheep, cattle and goats occur at irregular intervals of several years when exceptionally heavy rains favour the breeding of the mosquito vectors, and are distinguished by heavy mortality among newborn animals and abortion in pregnant animals. Humans become infected from contact with tissues of infected animals or from mosquito bite, and usually develop mild to moderately severe febrile illness, but severe complications, which occur in a small proportion of patients, include ocular sequelae, encephalitis and fatal haemorrhagic disease. Despite the occurrence of low case fatality rates, substantial numbers of humans may succumb to the disease during large outbreaks. Modified live and inactivated vaccines are available for use in livestock, and an inactivated vaccine was used on a limited scale in humans with occupational exposure to infection. The literature on the disease has been the subject of several extensive reviews from which the information presented here is drawn, except where indicated otherwise (Henning 1956; Weiss 1957; Easterday 1965; Peters and Meegan 1981; Shimshony and Barzilai 1983; Meegan and Bailey 1989; Swanepoel and Coetzer 2004; Flick and Bouloy 2005). In September 2000, the disease appeared in south-west Saudi Arabia and adjacent Yemen, and the outbreak lasted until early 2001 (Al Hazmi et al. 2003; Madani et al. 2003; Abdo-Salem et al. 2006). The virus was probably introduced with infected livestock from the Horn of Africa, and it remains to be determined whether it has become endemic on the Arabian Peninsula.

Abstract:

Lymphatic filariasis, a parasitic disease often resulting in severe lymphatic dysfunction and lymphedema, is perpetuated by an invasion of worms, delivered through mosquito bites, that reside, mature, and reproduce in the human lymphatic system. The disease cycle begins with stage 3 larvae (L3) leaving the mosquito and penetrating the dermal layer of the human while the mosquito is feeding where it eventually makes its way to a collecting lymphatic vessel where it resides for its adult life (up to 10 years) [1]. While many infected individuals will remain asymptomatic, a subset of patients will develop reconstruction of the tissue structure and the extreme swelling of the arms, legs, genitals and/or breasts. This elephantiasis occurs in over 10 million people worldwide and has a harsh negative effect on the infected individual’s ability to work and function in society.
