Recent Advances in Lepidoptera Gut Symbiotic Bacteria
Lepidopteran is one of the most diverse insect groups in nature and exerts a significant impact on ecosystems.As crucial symbionts of insects,gut bacteria play an important role in improving the adaptability of host insects to the environment.In this paper,the composition of lepidopteran gut symbiotic bacteria and their effects on hosts have been briefly reviewed,as well as the application of gut symbiotic bacteria in industry and agriculture.The source of gut bacteria in Lepidoptera is mainly discussed in this pa-per.Whereas in other studies,the source of lepidopteran gut bacteria is often neglected,however,it is an important prerequisite for lepidopteran insects to continuously and stably adapt to the environment.Effec-tively utilizing gut symbiotic bacteria is a crucial approach to addressing the damage caused by lepidopteran insects to agriculture and forestry,it also plays an important role in enhancing the economic benefits of in-sect-related industries.
