所有昆虫都被微生物定殖在昆虫外骨骼上、肠道和血腔中以及昆虫细胞内。昆虫微生物群通常不同于外部环境中的微生物，包括摄入的食物。具体地说，某些微生物类群受到昆虫栖息地的条件和资源、它们对昆虫免疫的耐受性以及它们传播的特定机制的青睐。驻留的微生物可以通过提供营养，特别是通过提供必需氨基酸、B族维生素以及对于真菌伙伴来说的甾醇，来促进昆虫的健康。一些微生物通过合成特定的毒素或改变昆虫的免疫系统来保护它们的昆虫宿主免受病原体、拟寄生虫和其他寄生虫的侵害。未来研究的优先事项包括阐明微生物对解毒的贡献，特别是植食性昆虫中的植物化感物质，以及对病原体的抗性;以及它们在昆虫-昆虫通信中的作用;以及操纵微生物群以控制昆虫害虫的潜在价值。
All insects are colonized by microorganisms on the insect exoskeleton, in the gut and hemocoel, and within insect cells. The insect microbiota is generally different from microorganisms in the external environment, including ingested food. Specifically, certain microbial taxa are favored by the conditions and resources in the insect habitat, by their tolerance of insect immunity, and by specific mechanisms for their transmission. The resident microorganisms can promote insect fitness by contributing to nutrition, especially by providing essential amino acids, B vitamins, and, for fungal partners, sterols. Some microorganisms protect their insect hosts against pathogens, parasitoids, and other parasites by synthesizing specific toxins or modifying the insect immune system. Priorities for future research include elucidation of microbial contributions to detoxification, especially of plant allelochemicals in phytophagous insects, and resistance to pathogens; as well as their role in among-insect communication; and the potential value of manipulation of the microbiota to control insect pests.
