褐飞虱腹部脂肪体中的共生菌对其寄主褐飞虱的生长繁殖起着重要作用。因此，用抗菌剂抑制共生菌对水稻褐飞虱的侵染是可行的。然而，抗菌剂对脂肪体微生物群落的影响以及微生物群落与死亡率的关系尚未完全阐明。观察到，在接触托霉素、戊唑醇和中生霉素后，脂肪体中酵母样共生体的总数减少，死亡率上升。此外，我们还发现，抗菌剂降低了脂肪体内的细菌多样性，增加了真菌多样性，并改变了细菌和真菌的群落结构。虽然细菌和真菌的总绝对丰度在抗菌药物暴露后有所下降，但沙雷氏菌的绝对丰度增加，表明在脂肪体中占优势的沙雷氏菌是参与抗菌素耐药的重要共生菌。经抗菌药物作用后，7个可能参与宿主营养发育功能的属全部从脂肪体中消失。总之，本研究丰富了抗菌处理下褐飞虱脂肪体中微生物群落的知识，并为进一步利用共生菌的干扰作用来帮助其他农药防治害虫奠定了基础。
Symbionts in the abdomen fat body of brown planthopper (BPH) play an important role in the growth and reproduction of their host, Nilaparvata lugens Stål (Hemiptera: Delphacidae). Thus, controlling BPH infection on rice by inhibiting symbionts with antimicrobials is feasible. However, the effect of antimicrobials on the microbiome in the fat body and the relationship between microbial community and mortality have not been fully elucidated. A decrease in the total number of yeast-like symbiotes in the fat body and elevated mortality were observed after exposure to toyocamycin, tebuconazole, and zhongshengmycin. Additionally, we found that the antimicrobials reduced bacterial diversity and increased fungal diversity in the fat body and altered the bacterial and fungal community structure. Although the total absolute abundance of bacteria and fungi decreased after antimicrobial exposure, the absolute abundance of Serratia increased, indicating that Serratia, which was the most dominant in the fat body, is an important symbiont involved in resistance to antimicrobials. After antimicrobial exposure, seven genera, which probably participated in the nutrition and development function of the host, were totally eliminated from the fat body. Overall, our study enriches the knowledge of microbiomes in the fat body of BPH under antimicrobial treatment and the disturbance of symbionts would be further used to help other pesticides to control pests.
