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,...
Cholesterol plays essential roles in animal development and disease progression. Here, we characterize the evolutionary pattern of canonical cholesterol biosynthesis pathway (CBP) kingdom using both genome-wide analyses functional experiments. CBP genes basal metazoans were inherited from their last common eukaryotic ancestor evolutionarily conserved for biosynthesis. The genomes deuterostomes retain almost full set genes, while Cnidaria many protostomes have independently experienced...
Abstract Parasitoids are ubiquitous in natural ecosystems. Parasitic strategies highly diverse among parasitoid species, yet their underlying genetic bases poorly understood. Here, we focus on the divergent adaptation of a specialist and generalist drosophilid parasitoids. We find that novel protein (Lar) enables active immune suppression by lysing host lymph glands, eventually leading to successful parasitism generalist. Meanwhile, another (Warm) contributes passive strategy attaching laid...
Many insect pests, including the brown planthopper (BPH), undergo windborne migration that is challenging to observe and track. It remains controversial about their patterns largely unknown regarding underlying genetic basis. By analyzing 360 whole genomes from around globe, we clarify sources of worldwide BPHs illuminate a landscape BPH showing East Asian populations perform closed-circuit journeys between Indochina Far East, while Malay Archipelago South Asia one-way Indochina. We further...
The oriental armyworm, Mythimna separata, is known for its long-distance seasonal migration and environment-dependent phase polymorphisms. Here, we present a chromosome-level genome reference integrate multi-omics, functional genetics, behavioral assays to explore the genetic bases of hallmark traits M. separata migration. Gene family comparisons show expansion gustatory receptor genes in this cereal crop pest. Functional investigation magnetoreception-related associated flight behaviors...
The success of an organism depends on the molecular and ecological adaptations that promote its beneficial fitness. Parasitoids are valuable biocontrol agents for successfully managing agricultural pests, they have evolved diversified strategies to adapt both physiological condition hosts competition other parasitoids. Here, we deconstructed parasitic in a highly successful parasitoid, Trichopria drosophilae , which parasitizes broad range Drosophila hosts, including globally invasive...
Abstract Intraspecific competition is a major force in mediating population dynamics, fuelling adaptation, and potentially leading to evolutionary diversification. Among the arms races between parasites, one of most fundamental intriguing behavioural adaptations counter-adaptations are superparasitism avoidance. However, underlying mechanisms ecological contexts these phenomena remain underexplored. Here, we apply Drosophila parasite Leptopilina boulardi as study system find that this...
The evolution of feeding habits leads to speciation in insects. Bactrocera true fruit flies display diverse across species. We combine behavioral and functional genomic studies probe the divergence between specialist B. minax generalist dorsalis. find that both vision olfaction contribute their respective host preferences, with a dominant effect over short range. Correspondingly, location-related genes are significantly enriched phototransduction pathway, which long-wavelength rhodopsin...
Black solider fly larvae and the gut microbiota can recycle nutrients from various organic wastes into valuable insect biomass. We found that Citrobacter amalonaticus, a commensal bacterium of insect, exerts beneficial effects on larval growth development expression many metabolic genes was significantly impacted by symbiont. To identify involved in host-symbiont interaction, we engineered symbiont to produce double-strand RNA enabled strain silence host environment where interaction takes...
Abstract As a gene required for sexual development, intersex ( ix ), functions in concert with the female‐specific product of doublesex dsx ) at end hierarchy to facilitate sex‐specific differentiation sexually dimorphic characters female Drosophila melanogaster . In present study, we initially identified homolog Gryllus bimaculatus , detection single isoform expressed both sexes. Phylogenetic analyses and multiple sequence alignment revealed that Gbix exhibited conservation. Here employed...
Abstract Insects have evolved a diversity of regulatory mechanisms to determine their sex. Understanding the molecular regulation insect sex determination is great significance in revealing general law and providing potential routes for genetic manipulation pest species. Although cascade doublesex ( dsx ) gene functions been well described some holometabolous insects, little known about this hemimetabolous insects. In study, we identified homolog Gryllus bimaculatus , which belongs...
Understanding the molecular basis of nocturnal and diurnal behaviors is crucial to uncovering adaptive specialization. Here, we employed black cutworm (Agrotis ipsilon, BCW) examine rhythmic gene repertoire in species. Daily eclosion patterns confirmed BCW's behavior. We generated daily transcriptomes for BCW compared them with those monarch butterfly (Danaus plexippus). Both species share a core set genes expression, indicating fundamental timekeeping mechanism Lepidoptera. Notably,...
Trichogramma dendrolimi is an essential egg parasitic wasp with a broad host range and has been widely used for controlling agricultural forestry pests. Despite the availability of fragmented genomes Trichogramma, high-quality, chromosome-level genome reference not yet available this diverse genus. In study, we assembled high-quality T. using PacBio CLR long sequencing further scaffolded it Hi-C technologies. The size was 216.24 Mb, featuring N50 39.07 98.79% scaffolds were anchored to five...
Sex determination has been studied in the model lepidopteran species Bombyx mori, but it remains poorly understood pests. In present study, we identified and characterized Masculinizer (Masc) gene a Noctuidae pest species, Agrotis ipsilon. Sequence analysis revealed that AiMasc encodes protein of 658 amino acids two CCCH-type zinc finger domains conserved cysteine residues (Cys-277 Cys-280). We assessed masculinizing activity BmN cells found induced expression male-specific doublesex...
Abstract The tea geometrid is a destructive insect pest on plants, which seriously affects production in terms of both yield and quality causes severe economic losses. also provides an important study system to address the ecological adaptive mechanisms underlying its unique host plant adaptation protective resemblance. In this study, we fully sequenced de novo assembled reference genome geometrid, Ectropis grisescens , using long sequencing reads. We presented highly continuous,...
