Abstract Many cockroach species have adapted to urban environments, and some been serious pests of public health in the tropics subtropics. Here, we present 3.38-Gb genome a consensus gene set American cockroach, Periplaneta americana . We report insights from both genomic functional investigations into underlying basis its adaptation environments developmental plasticity. In comparison with other insects, expansions families P. exist for most core likely associated environmental adaptation,...
Abstract A key characteristic of eusocial species is reproductive division labour. Honey bee colonies typically have a single queen and thousands sterile workers. Adult queens differ dramatically from workers in anatomy, physiology, behaviour lifespan. Young female can activate their ovaries initiate egg laying; these ‘reproductive’ behaviour. These differences, however, are on much smaller scale than those observed between the worker castes. Here, we use microarrays to monitor expression...
Cuticle penetration plays an important role as a mechanism of insecticide resistance, but the underlying molecular remains poorly understood. In Blattella germanica, cytochrome P450 gene, CYP4G19, is overexpressed in pyrethroid-resistant strain. Here, we investigated whether CYP4G19 involved biosynthesis hydrocarbons and further contributes to cuticular resistance B. germanica.Compared with susceptible strain, cockroaches showed lower permeability Eosin Y staining. Removal epicuticular...
Cereal aphids are major insect pests of wheat, which cause significant damages to wheat production. Previous studies mainly focused on the resistance different varieties one specific aphid species. However, reports physiology and defense responses cereal basically lacking. In this work, we studied feeding behavior three aphids: grain aphid, Sitobion avenae (Fabricius), greenbugs, Schizaphis graminum (Rondani), bird cherry-oat Rhopalosiphum padi (Linnaeus) winter infestation these with focus...
Abstract Background Regulation of worker behavior by dominant queens or workers is a hallmark insect societies, but the underlying molecular mechanisms and their evolutionary conservation are not well understood. Honey bee bumble colonies consist single reproductive queen facultatively sterile workers. The queens' influences on mediated largely via inhibition juvenile hormone titers, which affect division labor in honey bees reproduction bees. Studies identified transcription factor,...
Insect cuticular hydrocarbons (CHCs) serve as important intersexual signaling chemicals and generally show variation between the sexes, but little is known about generation of sexually dimorphic (SDHCs) in insects. In this study, we report molecular mechanism biological significance that underlie SDHC German cockroach Blattella germanica. Sexually mature females possess more C29 CHCs, especially contact sex pheromone precursor 3,11-DimeC29. RNA interference (RNAi) screen against fatty acid...
Melanin is involved in cuticle pigmentation and sclerotization of insects, which critical for maintaining structural integrity functional completeness insect cuticle. The 2 key enzymes tyrosine hydroxylase (TH) dopa decarboxylase (DDC) predicted melanin biosynthesis are usually conserved insects. However, it unclear whether their function related to epidermal permeability. In this study, we identified cloned the gene sequences BgTH BgDdc from Blattella germanica, revealed that they both...
Large amounts of hydrocarbons accumulate during vitellogenesis in the developing basal oocytes German cockroach Blattella germanica (L.), and all ovarian are deposited into an egg case (ootheca) oviposition. Hydrocarbons not synthesized by ovaries, but delivered hemolymph lipoproteins within oocytes. A native B. hydrocarbon, [(3)H]3,11-dimethylnonacosane, injected adult females various ages, was taken up ovaries relation to oocyte growth. Ovarian uptake hydrocarbon low day 0-1 females,...
Oviposition is an important reproductive behavior that triggered by mating in insects, and biogenic amines might be involved its regulation. The effects of on oviposition have only been studied a few insect species, the findings to date not conclusive. In addition, there are studies diamondback moth, Plutella xylostella L. Here, we tested how regulate P. injecting amine receptor antagonists into virgin mated females counting number eggs laid afterwards. Biogenic octopamine tyramine could...
In insects, male accessory gland proteins (ACPs) are important reproductive secreted by glands (MAGs) of the internal system. During mating, ACPs transferred along with sperms inside female bodies and have a significant impact on post-mating physiology changes females. Under sexual selection pressures, exhibit remarkably rapid divergent evolution vary from species to species. The diamondback moth, Plutella xylostella (L.) (Lepidoptera: Plutellidae), is major insect pest cruciferous...
Cuticular hydrocarbons (CHCs) have a critical role in preventing desiccation and penetration of xenobiotics insects. Previous studies shown that cytochrome P450 subfamily 4G (CYP4G) enzymes are oxidative decarbonylases, essential for CHC biosynthesis. However, it is unclear whether there functional differences between the two CYP4G genes most In Locusta migratoria, we identified (LmCYP4G62 LmCYP4G102). LmCYP4G102 plays synthesis CHCs, but function LmCYP4G62 unknown.We identified,...
Low proportion of essential amino acids (EAAs) is one the barriers for animals to use phloem as a diet. Endosymbionts with EAAs synthesis functions are considered crucial ameliorating lack in insects' diets. In this study, we transferred insects from cabbage-reared Myzus persicae population onto 3 new plant species including eggplant, tobacco and spinach. The performance on these plants was evaluated dynamics endosymbionts relation host alternation were recorded. We found that ratio largely...
The green peach aphid, Myzus persicae (Sulzer) (Hemiptera: Aphididae), is an important pest of many crops in the world and a vector more than 100 plant viruses. It major Brassica vegetables such as Chinese cabbage northern China. Chemical control extensively used to manage this aphid around world; however, development insecticide resistance has been obstacle facing growers. Host against M. not reported yet. In study, we investigated categories seven cultivars persicae. these included...
Insect cuticular hydrocarbons (CHCs) are organic compounds of the surface lipid layer, which function as a barrier against water loss and xenobiotic penetration, while also serving chemical signals. Plasticity CHC profiles can vary depending upon numerous biological environmental factors. Here, we investigated potential sources variation in Nilaparvata lugens, Laodelphax striatellus Sogatella furcifera, considered to be most important rice pests Asia. were quantified by GC/MS, factors...
