Similar to many other organisms, insects like Drosophila melanogaster, Hypothenemus hampei, and Cockroaches harbor diverse bacterial communities in their gastrointestinal systems. These bacteria, along with other microorganisms like fungi and archaea, are essential to the physiology of their insect hosts, forming intricate symbiotic relationships. These gut-associated microorganisms contribute to various vital functions, including digestion, nutrient absorption, immune regulation, and behavioral modulation. Notably, gut microbiota facilitates the breakdown of complex plant materials, synthesizes essential vitamins and amino acids, and detoxifies harmful substances, including pesticides. Furthermore, these microorganisms are integral to modulating host immune responses and enhancing disease resistance. This review examines the multifaceted roles of gut microbiota in insect physiology, with particular emphasis on their contributions to digestion, detoxification, reproduction, and environmental adaptability. The potential applications of gut microbiota in integrated pest management (IPM) are also explored. Understanding the microbial dynamics within insect pest species opens new avenues for pest control, including developing microbial biocontrol agents, microbial modifications to reduce pesticide resistance, and implementing microbiome-based genetic strategies. In particular, manipulating gut microbiota presents a promising approach to pest management, offering a sustainable and eco-friendly alternative to conventional chemical pesticides.
与许多其他生物类似，果蝇、咖啡豆象和蟑螂等昆虫在其胃肠道系统中拥有多样的细菌群落。这些细菌与真菌和古菌等其他微生物一起，对其昆虫宿主的生理机能至关重要，形成了复杂的共生关系。这些与肠道相关的微生物有助于多种重要功能，包括消化、营养吸收、免疫调节和行为调节。值得注意的是，肠道微生物群有助于分解复杂的植物物质，合成必需的维生素和氨基酸，并对包括农药在内的有害物质进行解毒。此外，这些微生物对于调节宿主免疫反应和增强抗病能力不可或缺。本综述探讨了肠道微生物群在昆虫生理机能中的多方面作用，特别强调了它们对消化、解毒、繁殖和环境适应性的贡献。还探讨了肠道微生物群在害虫综合管理（IPM）中的潜在应用。了解害虫物种内的微生物动态为害虫控制开辟了新途径，包括开发微生物生物防治剂、进行微生物改造以降低抗药性以及实施基于微生物组的遗传策略。特别是，操纵肠道微生物群为害虫管理提供了一种有前景的方法，为传统化学农药提供了一种可持续且环保的替代方案。
