The insect gut contains a complex and diverse microbial community, and the composition of the insect gut microbial community is influenced by multiple factors such as the host's genetics, dietary habits, and the external environment. The host's immune system maintains the stability and balance of the microbial community through a number of mechanisms. The microorganisms in this community play key roles in the nutrient metabolism, detoxification, immune regulation, development, and behaveior of insects. In recent years, the relevant literature has reported advances in the study of insect gut microbes, indicating the potential applications of insect gut microbes in several fields. The aim of this review is to provide a comprehensive overview of the current information on the structure of insect gut microbial communities and complex host-microbe-environment interactions. The diversity of insects' gut microbial communities and the functions of their gut microbes are revealed. By studying insect gut microbial communities, we can gain insights into the functions of these microbes in the host and explore the causal relationships between them and the host's physiology and behavior. This will not only help us to understand the mechanism of action of the microbiome, but also provide a basis for the development of innovative biotechnology based on insect gut microbes. This research has significant theoretical value in academia and also has a wide range of applications in agriculture, environmental protection, industrial production, and healthcare.
昆虫肠道含有一个复杂多样的微生物群落，昆虫肠道微生物群落的组成受宿主遗传学、饮食习惯和外部环境等多种因素影响。宿主的免疫系统通过多种机制维持微生物群落的稳定性和平衡。这个群落中的微生物在昆虫的营养代谢、解毒、免疫调节、发育和行为中发挥着关键作用。近年来，相关文献报道了昆虫肠道微生物研究的进展，表明昆虫肠道微生物在多个领域具有潜在应用。本综述的目的是全面概述当前关于昆虫肠道微生物群落结构以及复杂的宿主-微生物-环境相互作用的信息。揭示昆虫肠道微生物群落的多样性及其肠道微生物的功能。通过研究昆虫肠道微生物群落，我们可以深入了解这些微生物在宿主中的功能，并探索它们与宿主生理和行为之间的因果关系。这不仅有助于我们理解微生物组的作用机制，还为基于昆虫肠道微生物的创新生物技术开发提供依据。这项研究在学术界具有重要的理论价值，在农业、环境保护、工业生产和医疗保健等方面也有广泛应用。
