Dry conditions increase blood feeding in mosquitoes, but it is unknown if dehydration-induced bloodmeals are increased beyond what necessary for reproduction. In this study, we investigated the role of dehydration secondary behaviors mosquitoes. Following an initial bloodmeal, prolonged exposure to dry mosquitoes by nearly two-fold, and chronic allowed survive up 20 days without access water. Exposure desiccating following a bloodmeal resulted activity, decreased sleep levels, prompted...

ABSTRACT Sleep is an evolutionarily conserved process that has been described in different animal systems. For insects, sleep characterization primarily achieved using behavioral and electrophysiological correlates a few mosquitoes, which are important vectors of disease-causing pathogens, not directly examined. This surprising as circadian rhythms, have well studied influence other In this study, we characterized mosquitoes body posture analysis correlates, quantified the effect deprivation...

Sleep and pregnancy are contentious bedfellows; sleep disorders disturbances associated with adverse outcomes, although much is still unknown about this relationship. have been studied in many models, but most focus heavily on mammals. However, ubiquitous across the animal kingdom - a hallmark of convergent evolution; similarly shared feature diverse species. Here, we present an ideal model which to study dynamics between invertebrates. The Pacific beetle mimic cockroach, Diploptera punctata...

Parasites harm host fitness and are pervasive agents of natural selection capable driving the evolution resistance traits. Previously we demonstrated evolutionary responses to artificial for increasing behavioral immunity Gamasodes queenslandicus mites Drosophila melanogaster. Here, report transcriptional shifts in metabolic processes due mite resistance. We also show decreased starvation increased use nutrient reserves flies from mite-resistant lines. Resistant lines exhibited activity,...

Mosquito-borne diseases have caused more than 1 million deaths each year. There is an urgent need to develop effective way reduce mosquito-host interaction mitigate disease transmission. Sugar diets long been linked abnormal physiology in animals, making them potential candidates for mosquito control. Here, we show the impact of sugar on humidity preference and survival Aedes aegypti (Gainesville) Culex pipiens (Buckeye). Two-choice assays with high low relative (80% 50% RH) that...

Abstract Survival through periods of drought is critical for mosquitoes to reside in semi-arid regions with humans. Dry conditions increase blood feeding propensity mosquitoes, but it unknown if dehydration-induced bloodmeals beyond what necessary reproduction. Following a bloodmeal, prolonged exposure dry increased secondary by nearly two-fold, and chronic allowed survive up twenty days without access water sources. This refeeding did not alter the number eggs generated, suggesting this...

Abstract Mosquitoes occupy a wide range of habitats where they experience various environmental conditions. The ability some species, such as the tiger mosquito, Aedes albopictus , to adapt local conditions certainly contributes their invasive success. Among traits that remain be examined, mosquitoes’ time activity with host population has been suggested significant epidemiological importance. However, whether different populations display heritable differences in chronotype not examined....

Abstract Aedes aegypti is an important mosquito vector of human disease with a wide distribution across the globe. Climatic conditions and ecological pressure drive differences in biology several populations this mosquito, including blood-feeding behavior competence. However, no study has compared activity and/or sleep among different populations/lineages Ae. . Having recently established sleep-like states three species observable timing amount species, we investigated levels 17 lines drawn...

Abstract Aedes aegypti is an important mosquito vector of human disease with a wide distribution across the globe. Climatic conditions and ecological pressure drive differences in biology several populations this species, including blood‐feeding behaviour competence. However, no study has compared activity and/or sleep among different populations/lineages Ae. . Having recently established sleep‐like states three species observable timing amount we investigated levels 17 lines drawn from both...

Abstract Ticks are blood-feeding arthropods responsible for the transmission of disease-causing pathogens to a wide range vertebrate hosts, including livestock and humans. Tick-borne diseases have been implicated in significant economic losses production, this threat will increase as these obligate parasites widen their geographical ranges. Similar other ectotherms, thermal stress due changing global temperatures has shown influence tick survival distribution. However, studies on extreme...

Rapid hardening is a process that quickly improves an animal's performance following exposure to potentially damaging stress. In this study of the Antarctic midge, Belgica antarctica (Diptera, Chironomidae), we examined how rapid in response dehydration (RDH) or cold (RCH) male pre- and post-copulatory function when insects are subsequently subjected exposure. Neither RDH nor RCH improved survival lethal stress, but activity mating success sublethal were enhanced. Egg viability decreased...

Parasites harm host fitness and are pervasive agents of natural selection to evolve defense strategies Host defensive traits in populations typically show genetic variation, which may be maintained when parasite resistance imposes costs on the absence parasites. Previously we demonstrated significant evolutionary responses artificial for increasing behavioral immunity Gamasodes queenslandicus mites replicate lines Drosophila melanogaster. Here, report transcriptional shifts metabolic...

Abstract Environmental sustainability is a huge challenge in Africa as the region currently struggling to provide sustainable systems support daily human activities. Such activities many African organisations include paper‐based information storage and communication which are not ecofriendly place burden on forest resources. This study therefore focused implication of overusing paper an university. Fifty offices university were surveyed 59 questionnaires administered. The transcribed...

Abstract Rapid hardening is a process that quickly improves an animal’s performance following exposure to potentially damaging stress. Features of reproduction can be improved by rapid hardening, but little known about how may contribute physiological responses in the cold environment Antarctica.
