Chemical communication is widespread among insects and exploited to adjust their behavior, such as food and habitat seeking and preferences, recruitment, defense, and mate attraction. Recently, many studies have revealed that microbial symbionts could regulate host chemical communication by affecting the synthesis and perception of insect semiochemicals. In this paper, we review recent studies of the influence of microbial symbionts on insect chemoreception. Microbial symbionts may influence insect sensitivity to semiochemicals by regulating the synthesis of odorant-binding proteins or chemosensory proteins and olfactory or gustatory receptors and regulating host neurotransmission, thereby adjusting insect behavior. The manipulation of insect chemosensory behavior by microbial symbionts is conducive to their proliferation and dispersal and provides the impetus for insects to change their feeding habits and aggregation and dispersal behavior, which contributes to population differentiation in insects. Future research is necessary to reveal the material and information exchange between both partners to improve our comprehension of the evolution of chemoreception in insects. Manipulating insect chemoreception physiology by inoculating them with microbes could be utilized as a potential approach to managing insect populations.
化学通讯在昆虫中广泛存在，并被用于调节它们的行为，如寻找食物和栖息地、选择偏好、招募同伴、防御以及吸引配偶等。最近，许多研究表明，微生物共生体可以通过影响昆虫信息素的合成和感知来调节宿主的化学通讯。在本文中，我们综述了微生物共生体对昆虫化学感受影响的最新研究。微生物共生体可能通过调节气味结合蛋白或化学感受蛋白以及嗅觉或味觉受体的合成，以及调节宿主的神经传递，来影响昆虫对信息素的敏感性，从而调节昆虫的行为。微生物共生体对昆虫化学感受行为的操控有利于它们的增殖和扩散，并为昆虫改变取食习性以及聚集和扩散行为提供了动力，这有助于昆虫种群的分化。未来有必要开展研究以揭示双方伙伴之间的物质和信息交换，从而增进我们对昆虫化学感受进化的理解。通过给昆虫接种微生物来操控其化学感受生理机能，有望成为一种潜在的害虫种群治理方法。
