The nutritional requirements of mosquitoes include both sugar (generally derived from the nectar of flowers) and blood (humans or animals). Mosquitoes express different degrees of preferences towards hosts depending on behavioral, ecological, and physiological factors. These preferences have implications for mosquito-borne disease risk. The present study is directed to reveal the effect of the human blood groups on the fecundity and fertility of the malaria vector Anopheles stephensi. In laboratory tests, mosquitoes were fed on ABO blood groups via artificial membrane feeders, and the level of attraction against different blood groups was tested by the electroantennogram and wind tunnel bioassay under control conditions. Results indicate that the female mosquitoes had a strong preference towards the blood group B, while in the case of females fed on O blood group had the highest digestibility rate. Overall, the human blood type had a significant impact on the fecundity and fertility of female An. stephensi. The highest numbers of eggs are laid, in the case of blood group B, (mean (± SD)) 216.3 (8.81) followed by the AB, 104.06 (7.67), and O, 98.01 (7.04). In the case of blood group B, females attain the highest fertility of about 92.1 (9.98). This study provides novel insight into the ABO blood type host choice of the mosquitoes that are still partially unknown and suggests encouraging personal protection for relevant individuals within communities at risk, which is a useful tool for preventing malaria where the An. stephensi is present as a dominant vector.

“…These blood-feeding rates can possibly be increased further by using other laboratory animals (mammals) and/or altering starvation periods or environmental conditions during blood-feeding. In addition, fecundity of C. insignis may also be potentially increased by using a mammalian blood source (versus avian blood source used in this study) as host blood meal source can alter fecundity in hematophagous species [31,32]. However, further studies will be needed to test these hypotheses.…”

BackgroundCulicoides insignis Lutz (Diptera: Ceratopogonidae) is a confirmed vector of bluetongue virus (BTV) throughout the American tropics and a possible vector of epizootic hemorrhagic disease virus (EHDV) in Florida. Despite its importance, fundamental information on the biology and ecology of this species is lacking. In this study, we examined the oviposition and larval development of C. insignis under laboratory conditions and attempted colonization of this species. MethodsLive C. insignis females were collected from the field using CDC-UV-LED traps, allowed to blood-feed on live chicken, and given various natural substrates for oviposition in two-choice assays. The eggs deposited were transferred to 0.3% agar slants and the hatched larvae were provided a diet of Panagrellus redivivus Linnaeus nematodes. ResultsCulicoides insignis females exhibited an overall oviposition preference for dishes containing mud from their larval habitat as gravid females deposited a significantly higher number of eggs on these dishes (35.3 eggs/female) than on deionized water (DI) substrates (17.7eggs/female). The ovipositing females also deposited a higher percentage of eggs on substrates with habitat mud and other organically enriched muds (≥ 75.2%) compared to DI substrates (31.0%). The larvae developed successfully to adulthood on the nematode diet, exhibiting high overall larval survival rates (85.0%). Sex-ratios of the F1 generation were male biased ~3:1 (M:F). Captive mating could not be induced in the F1 adults. ConclusionsMud from the larval habitat and other organically enriched muds provide strong oviposition cues to C. insignis. Further studies will be needed to examine whether these cues are olfactory/tactile in nature. Further studies will also be needed to characterize the larval habitat of C. insignis and identify the key biotic/abiotic factors influencing midge oviposition in the field. This information, in the long term, can be potentially exploited to discourage the oviposition of C. insignis in local habitats. The agar/nematode method is effective for the rearing of C. insignis larvae. However, further studies will be needed to address the issue of male-biased sex-ratios in the progeny. Further studies will also be needed to examine the mating habits/cues of C. insignis in nature, which may provide clues towards inducing captive mating in the F1 adults.
