Grassland habitat fragmentation leads to changes in the size,connectivity,and structure of grassland habitats,which is one of the primary causes of the decline in grassland biodiversity. The frag-mentation has potential impacts on locust outbreaks and the reduction of their natural enemy insect di-versity. This paper employs bibliometric analysis to statistically examine relevant domestic and interna-tional literature,with a focus on summarizing the effects of grassland habitat fragmentation on locust outbreaks and their natural enemy insects. It also provides perspectives on enhancing the control capac-ity of natural enemy insects,reducing locust population outbreaks,and increasing the diversity of natu-ral enemy insects.
