Abstract Seasonal plasticity in insects is often triggered by temperature and photoperiod changes. When climatic conditions become sub-optimal, might undergo reproductive diapause, a form of seasonal delaying the development organs activities. During cuticular hydrocarbon (CHC) profile, which covers insect body surface, also change to protect from desiccation cold temperature. However, CHCs are important cues signals for mate recognition changes CHC composition affect recognition. In present study, we investigated profile mating success Drosophila suzukii 1- 5-day-old males females summer winter morphs. compositions differed with age no significant differences were found between sexes same morph. The results behavioral assays show that morph pairs start earlier their life, have shorter duration, more offspring compared pairs. We hypothesize profiles morphs adapted survive conditions, potentially at cost reduced cues.

Ants patrol foliage and exert a strong selective pressure on herbivorous insects, being their primary predators. As ants are chemically oriented, some organisms that interact with them (myrmecophiles) use chemical strategies mediated by cuticular hydrocarbons (CHCs) to deal ants. Thus, better understanding of the ecology evolution mutualistic interactions between myrmecophiles depends accurate recognition these strategies. Few studies have examined whether treehoppers may an additional strategy called camouflage reduce ant aggression, none considered highly polyphagous pest insects. We analyzed similarity CHC profiles three host plants from plant families (Fabaceae, Malvaceae, Moraceae) facultative myrmecophilous honeydew-producing treehopper

ABSTRACT Climate change is predicted to increase the spread of mosquito-borne viruses, but genetic mechanisms underlying influence environmental variation on ability insect vectors transmit human pathogens unknown. In response a changing climate, mosquitoes will experience longer periods drought. An important physiological dry environments protection against dehydration, here defined as desiccation tolerance. While temperature known impact interactions between mosquito and virus, role dehydration remains We identified two genetically diverse lines Aedes aegypti , major arbovirus vector, with marked differences in To determine these contrasting lines, we compared gene expression profiles desiccant- non-desiccant-treated individuals both desiccation-tolerant -susceptible by RNAseq. Gene analysis demonstrated that several genes are differentially expressed stress lines. The most highly transcript under desiccation-susceptible line encodes peritrophin protein, Ae-Aper50 .

ABSTRACT Major latitudinal clines have been observed in Drosophila melanogaster , a human commensal that originated tropical Africa and has subsequently dispersed globally to colonize temperate habitats. However, despite the crucial role pathogens play species distribution, our understanding of how geographical factors influence disease susceptibility remains limited. This investigation explored effects biomes on resistance using common fly pathogen Metarhizium anisopliae 43 global populations. The findings revealed correlations between gradients sleep duration, temperature, humidity. Although enhanced defenses may be driven by fungal diversity at latitudes, most disease‐resistant males also showed highest desiccation. suggests potential trade‐offs abiotic stress resistance, necessary for survival habitats, resistance. Furthermore, study uncovered interactions sex, mating status, sleep, stresses, affecting Notably, longer‐sleeping virgin flies survived infections longer, with additional daytime post‐infection being protective, particularly resistant lines. These observations support hypothesis defense are intertwined traits linked organismal fitness subject joint clinal evolution.

Animals exhibit different extents of sexual dimorphism in a variety phenotypes. Sex differences longevity, one the most complex life history traits, have also been reported. Although lifespan regulation has studied extensively fruit fly, Drosophila melanogaster, sex not consistent previous studies. To explore this issue, we revisited question by examining and stress resistance both sexes among 15 inbred strains. We first found positive correlations between males females from same strain terms to starvation desiccation stress. difference male female flies varied greatly depending on strain, across all strains collectively had longer lifespan. In contrast, showed better observed greater variation females. Unexpectedly, there was no notable correlation three types either or Overall, our study provides new data regarding fly resistance; information may promote investigation mechanisms underlying longevity future research.

Traits that allow species to survive in extreme environments such as hot-arid deserts have independently evolved multiple taxa. However, the genetic and evolutionary mechanisms underlying these traits thus far not been elucidated. Here, we show Drosophila mojavensis , a desert-adapted fruit fly species, has high desiccation resistance by producing long-chain methyl-branched cuticular hydrocarbons (mbCHCs) contribute lipid layer reducing water loss. We ability synthesize longer mbCHCs is due changes fatty acyl–CoA elongase ( mElo ). knockout D. led loss of reduction at temperatures but did affect mortality either or desiccating conditions individually.
