Chouioia cunea are known to exploit in varying degrees a wide range of lepidopteran species and its offspring development may vary with host species. This study examined preimaginal larval gut microbiota parasitizing five folivorous hosts including Hyphantria (referred thereafter as CcHc), Antherea pernyi (CcAp), Helicoverpa armigera (CcHa), Spodoptera exigua (CcSe), frugiperda (CcSf). Though rates parasitism eclosion did not change species, the period number eclosed varied hosts, shortest CcSf highest from CcAp. For microbiota, though phylum Proteobacteria was dominant for attacking CcAp, Firmicutes so other hosts. All microbial genera except Enterococcus were less abundant than The database-based predictions indicate significant positive correlation between Cutibacterium Aureimonas relative wasp emergence, while Blastomonas exhibits strong association developmental period. Our results imply potential relevance community larvae attacked by C. cunea.

Chelonus formosanus is a parasitic wasp capable of parasitizing various Noctuidae pests, including the highly invasive Spodoptera frugiperda, and it demonstrates strong pest control potential. Both egg larval stages primarily occur within host organism, total developmental time from to adult approximately 19.62 days. To investigate microbial communities at different stages, we performed 16S rDNA sequencing (V1–V9 region) using PacBio identified 404 bacterial species belonging 61 classes, 116 orders, 182 families, 308 genera across larval, pupal, female, male stages. Bacterial diversity richness varied with Enterobacter Enterococcus dominating in larvae pupae Pseudomonas emerging as dominant female adults. In contrast, adults predominantly resided Ralstonia Achromobacter. The predicted functions bacteria C. are marked by high abundance metabolic pathways. This study provides comprehensive understanding morphology contributes practical pests. Additionally, our findings preliminarily characterized community laying groundwork for its functional study.

Summary Pathogen infection in host plants can alter the attraction and adaptability of herbivorous insects. Female adult insects often exhibit selective behaviours based on their environmental experiences, enabling offspring to avoid adverse conditions ensuring healthy growth development. However, comprehensive studies integrating both perspectives fitness plant validate significance such parental ‘Mother knows worst’ experiences remain limited. Building our previous findings that female Conogethes punctiferalis (Yellow peach moth, YPM) adults oviposition avoidance behaviour towards corn infected with Trichoderma asperellum , we further confirmed by T. significantly inhibits development YPM larvae. Feeding decreases larval gut microbiota diversity, core abundance led differential expression key genes juvenile hormone metabolic pathway. Moreover, content flavonoid wogonin, a secondary metabolite, was increased corn. In vitro feeding experiments revealed wogonin negatively impacts causing accumulation suppressing microbial strains. This study validates adaptive empiricism from perspective offspring, while elucidating mechanisms which microbial‐mediated resistance against insects, as well for exploring utilizing effective biocontrol resources YPMs.
