摘要: While the interconnections between soil microbial communities and herbivorous insects have been extensively researched, few studies have explored soil bacterial relationships with parasitoids of herbivorous insects, and this important relationship is a factor in exploring the key to biological control of pests. Additionally, there is limited information concerning the microbial responses of insects to changes in the soil environment and their selection for long-term adaptation. In this context, we employed 16S rRNA sequencing to analyze a diverse set of soil, plant, and insect samples collected from field and greenhouse settings. The results reveal bacterial communities associated with Aphis gossypii and its parasitoid Binodoxys communis in the field were more dependent on soil conditions than those under greenhouse conditions. Insects and soil displayed similar compositional structures and dominant genera in the field. The bacterial composition of adults of A. gossypii, pupae of B. communis, and adult B. communis domesticated in long-term fixed greenhouse environments is closer to that of cotton leaves. We identified Bacillus as a critical genus linking soil, herbivorous insects and natural enemy microbiomes, and that Bacillus may be correlated with adaptations in A. gossypii or B. communis. Although there were considerable differences in the bacterial composition of field and greenhouse samples, functional predictions were consistent across the two environments, suggesting that community shaping is selective.
