Abstract The fall armyworm ( Spodoptera frugiperda ) is a lepidopteran insect pest that causes huge economic losses. This notorious has rapidly spread over the world in past few years. However, mechanisms of rapid dispersal are not well understood. Here, we report chromosome‐level assembled genome armyworm, named ZJ‐version, using PacBio and Hi‐C technology. sequenced individual was female collected from Zhejiang province China had high heterozygosity. size ZJ‐version 486 Mb, containing 361...
Parasitoid wasps are rapidly developing as a model for evolutionary biology. Here we present chromosomal genomes of two Anastatus wasps, A. japonicus and fulloi, leverage these to study fundamental questions-genome size evolution venom evolution. shows much larger genome than is known among other with unexpectedly recent bursts LTR retrotransposons. Importantly, several genomic innovations, including Piwi gene family expansion, ubiquitous expression profiles, well transposable element-piRNA...
Abstract Parasitoid wasps represent a large proportion of hymenopteran species. They have complex evolutionary histories and are important biocontrol agents. To advance parasitoid research, combination Illumina short‐read, PacBio long‐read Hi‐C scaffolding technologies was used to develop high‐quality chromosome‐level genome assembly for Pteromalus puparum , which is an pupal endoparasitoid caterpillar pests. The has aided in studies venom detoxification genes. assembled size 338 Mb with...
The ectoparasitic wasp Habrobracon hebetor (Hymenoptera, Braconidae) can parasitize various species of lepidopteran pests. To maximize its potential for biological control, it is necessary to investigate gene function through genome engineering.
Abstract Background Components of excretory/secretory products (ESPs) helminths have been proposed as vaccine targets and shown to play a role in modulating host immune responses for decades. Such research interest is further increased by the discovery extracellular vesicles (EVs) ESPs parasitic worms. Although efforts made reveal cargos EVs, little known about proteomic differences between EVs canonical released worms from animals. Methods The total Haemonchus contortus (barber’s pole worm)...
Animal venom systems have emerged as valuable models for investigating how novel polygenic phenotypes may arise from gene evolution by varying molecular mechanisms. However, a significant portion of genes produce alternative mRNA isoforms that not been extensively characterized, hindering comprehensive understanding biology. In this study, we present full-length isoform-level profiling workflow integrating multiple RNA sequencing technologies, allowing us to reconstruct high-resolution...
Hymenoptera comprise extremely diverse insect species with extensive variation in their life histories. The Dryinidae, a family of solitary wasps Hymenoptera, have evolved innovations that allow them to hunt using venom and pair chelae developed from the fore legs can grasp prey. Dryinidae larvae are also parasitoids Auchenorrhyncha, group including common pests such as planthoppers leafhoppers. Both these traits make effective valuable for pest control, but little is yet known about genetic...
Abstract Background A fundamental feature of parasitism is the nutritional exploitation host organisms by their parasites. Parasitoid wasps lay eggs on arthropod hosts, exploiting them for nutrition to support larval development using diverse effectors aimed at regulating metabolism. However, genetic components and molecular mechanisms basis such exploitation, especially utilization amino acid resources, remain largely unknown. To address this question, here, we present a chromosome-level...
Abstract The ectoparasitoid wasp Theocolax elegans is a cosmopolitan and generalist pteromalid parasitoid of several major storage insect pests, can effectively suppress host population in warehouses. However, little molecular information about this currently available. In study, we assembled the genome T. using PacBio long-read sequencing, Illumina Hi-C methods. assembly 662.73 Mb length with contig scaffold N50 values 1.15 88.8 Mb, respectively. contains 56.4% repeat sequences 23,212...
Abstract Trait regression and loss have occurred repeatedly in numerous lineages throughout evolutionary history response to changing environments. In parasitoid wasps, a mega-diverse group of hymenopteran insects, or reduction yolk the egg has been reported many species. This phenotypic change likely evolved as shift from ectoparasitism endoparasitism. However, genetic basis this trait impact its on genome evolution remain poorly understood. Here, we performed comparative genomic analysis...
Parasitoid wasps inject venom containing complex bioactive compounds to regulate the immune response and development of host arthropods sometime paralyze arthropods. Although extensive studies have been conducted on identification proteins in larval parasitoids, relatively few examined pupal parasitoids. In our current study, a combination transcriptomic proteomic methods was used identify 64 putative from Pachycrepoideus vindemmiae, an ectoparasitoid Drosophila. Expression analysis revealed...
Habrobracon hebetor is a parasitoid wasp capable of infesting many lepidopteran larvae. It uses venom proteins to immobilize host larvae and prevent larval development, thus playing an important role in the biocontrol pests. To identify characterize its proteins, we developed novel collection method using artificial (ACV), i.e., encapsulated amino acid solution paraffin membrane, allowing wasps inject venom. We performed protein full mass spectrometry analysis putative collected from ACV...
Abstract We identified a 9332-nucleotide-long novel picornaviral genome sequence in the transcriptome of an agriculturally important parasitoid wasp (Pachycrepoideus vindemmiae (Rondani, 1875)). The virus, Rondani’s virus 1 (RoWV-1), contains two long open reading frames encoding nonstructural and structural protein, respectively, is 3’-polyadenylated. Phylogenetic analyses firmly place RoWV-1 into dicistrovirid genus Cripavirus. detected various tissues life stages wasp, with highest load...
Miniaturization has occurred in many animal lineages, including insects and vertebrates, as a widespread trend during evolution. Among Hymenoptera, miniaturization taken place some parasitoid wasp lineages independently, may have contributed to the diversity of species. However, genomic basis is little understood. Diverged approximately 200 Ma, Telenomus wasps (Platygastroidea) Trichogramma (Chalcidoidea) both evolved highly reduced body size representing paradigmatic example convergent...
Nuclear hormone receptors (NHRs) are emerging target candidates against nematode infection and resistance. However, there is a lack of comprehensive information on NHR-coding genes in parasitic nematodes. In this study, we curated the nhr gene family for 60 major nematodes from humans animals. Compared with free-living model organism Caenorhabditis elegans, remarkable contraction was revealed species, genetic diversification conservation unveiled among Clades I (10-13), III (16-42), IV...
The green rice leafhopper, Nephotettix cincticeps (Hemiptera: Cicadellidae), is a key insect vector transmitting dwarf virus (RDV) that causes disease. We discovered novel iflavirus from the transcriptomes of N. and named it as positive-stranded RNA virus-1 (NcPSRV-1). viral genome consists 10,524 nucleotides excluding poly(A) tail contains one predicted open reading frame encoding polyprotein 3,192 amino acids, flanked by 5' 3' untranslated regions. NcPSRV-1 has typical arrangement...
In this study, an eight-week feeding trial was performed to investigate the effects of different taurine supplementation levels (0.0% as control, 1.0%, 1.5%, 2.0%, 2.5%, and 3.0%) on growth performance, lipid composition, antioxidant ability in juvenile ivory shells
In this study, the flavor compounds of ivory shell (Babylonia areolata) and their changes caused by ammonia salinity stresses were studied. Ammonia stress improved contents free amino acids (FAAs), 5'-adenosine monophosphate (AMP), citric acid, some mineral ions such as Na+, PO43-, Cl-. The FAA decreased with increasing salinity, while opposite results observed in most inorganic (e.g., K+, Mg2+, Mn2+, Cl-). Hyposaline hypersaline increased AMP acid compared to control group. equivalent umami...
