The insect gut is a complicated ecosystem that inhabits a large number of symbiotic bacteria. As an important organ of the host insect, the symbiotic bacteria of the insect gut play very important roles in regulating physiological and metabolic processes. Recently, much progress has been made in the study of symbiotic bacteria in insect guts with the development of high-throughput sequencing technology and molecular biology. This review summarizes the primary functions of symbiotic bacteria in insect guts, such as enhancing insecticide resistance, facilitating food digestion, promoting detoxification, and regulating mating behavior and egg hatching. It also addresses some possible pathways of gut bacteria symbiont regulation governed by external habitats, physiological conditions and immunity of the host insect. This review provides solid foundations for further studies on novel theories, new technologies and practical applications of symbiotic bacteria in insect guts. © 2024 Society of Chemical Industry.

昆虫肠道细菌的功能和调控


昆虫肠道是一个复杂的生态系统，栖息着大量的共生细菌。昆虫肠道共生菌作为宿主昆虫的重要器官，在调节生理和代谢过程中发挥着非常重要的作用。近年来，随着高通量测序技术和分子生物学的发展，昆虫肠道共生细菌的研究取得了很大进展。本文综述了昆虫肠道共生细菌的主要功能，如增强杀虫剂抗性、促进食物消化、促进解毒、调节交配行为和卵孵化等。它还探讨了受外部栖息地、生理条件和宿主昆虫免疫力控制的肠道细菌共生调节的一些可能途径。该综述为进一步研究昆虫肠道共生菌的新理论、新技术和实际应用奠定了坚实的基础。 © 2024 化学工业协会。
