Abstract Background Nitrogen is considered the most limiting nutrient element for herbivorous insects. To alleviate nitrogen limitation, insects have evolved various symbiotically mediated strategies that enable them to colonize nitrogen-poor habitats or exploit diets. In frugivorous tephritid larvae developing in fruit pulp under stress, it remains largely unknown how obtained and larval development completed. Results this study, we used metagenomics metatranscriptomics sequencing...
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...
Gut microbiota mediating insect-plant interactions have many manifestations, either by provisioning missing nutrients, or overcoming plant defensive reactions. However, the mechanism which gut empower insects to survive a variety of secondary metabolites remains largely unknown. Bactrocera minax larvae develop in immature citrus fruits, present numerous phenolic compounds that challenge larvae. To explore role microbes host use and adaptability, we uncovered mechanisms phenol degradation...
Cascading regulation of signaling pathways plays a crucial role in insect growth, development, and adaptation. However, how insects employ cascades to regulate detoxification gene expression enhance resistance is not well understood. In the current study, we investigated MAPK pathway mediating nitenpyram Nilaparvata lugens. qRT-PCR western-blot analyses revealed that both transcription protein levels NlJNK NlERK were upregulated resistant strain, these changes can be induced by exposure...
The enhanced detoxification capacity caused by the induction or constitutive overexpression of metabolic enzyme genes has complicated sustainable and efficient pest control strategies. This study clarified effects two P450 genes, CYP4CE3 CYP6FJ3, on multiple insecticides in Sogatella furcifera. chimeric double-stranded RNA (ch-dsRNA) these was obtained using L4440-HT1115 (DE3) RNase III- system, interference (RNAi) effectiveness ch-dsRNA verified microinjection. MON-NH2 subsequently used to...
Abstract BACKGROUND RNA interference (RNAi) technology has been put forward as a promising method for pest control and resistance management. Mining highly efficient lethal genes constructing stable double‐stranded (dsRNA) delivery systems are of great significance to improve the application potential RNAi technology. RESULTS In this study, we characterized molting‐related gene, NlCYP303A1 , in Nilaparvata lugens that was expressed cuticle at end stages each instar nymphs. Silencing...
Insects employ various types of gustatory receptors (GRs) to identify nutrient-rich food and avoid toxic substances. The larval system is the critical checkpoint for acceptance or rejection. As a specialist herbivore, larvae Bactrocera minax feed only on unripe citrus fruits. However, how use GRs check adapt secondary metabolites in fruits remains unknown. In this study, we first performed developmental expression profiles showing that most BminGRs genes were highly expressed 1st 2nd instar...
Pair-rule genes were identified and named for their role in segmentation animal embryos. Paired, a homolog of mammalian PAX3, acts as one several pair-rule is key defining the boundaries future parasegments segments during insect embryogenesis.We cloned paired gene from oriental fruit fly, Bactrocera dorsalis, then applied CRISPR/Cas9-mediated genome editing to investigate its physiological function embryonic stage this pest. We transcript B. which encodes protein containing Paired Box...
Plants perceive and orchestrate defense responses when herbivorous insects are ovipositing. Fruits, as a crucial reproductive organ in plants, have rarely been researched on the to insect eggs. Here, we found that oviposition by specialist
Abstract Temperature strongly impacts the rates of physiological and biochemical processes, which in turn can determine survival population size insects. At low temperatures performance is limited, however, cold tolerance at temperature be improved after short- or long-term acclimation many insect species. To understand mechanisms underlying acclimation, we sequenced compared transcriptome blowfly Chrysomya megacephala under rapid hardening (RCH) (LCA) conditions. The RCH response was...
Abstract The adaptation of phytophagous insects to host defence is an important aspect plant-insect interactions. reciprocal adaptability between specialist and their hosts have been adequately explored; however, the mechanisms underlying tephritid fruit fly specialists, a group notorious pests worldwide, unripen fruits remain elusive. Here, plant metabolomes insect transcriptomes were analysed for first time explore interaction unripe citrus Chinese Bactrocera minax . Seventeen secondary...
