Abstract:Locust has been a major pest of China's agriculture, forestry, and animal husbandry since ancient times, causing huge losses to agriculture. Researchers at home and abroad have conducted in-depth research on this pest. With the advances in the microecology of insect gut, the gut microbiome of locust has become a research focus. Meanwhile, the rapid development of sequencing technology has facilitated the research in this field. This paper summarizes the research progress in the diversity, function, and research methods of locust gut microbiome and puts forward the future research prospects.
