Effect of grazing on insect communities in grassland ecosystems: Research status and progress

Grazing is not only the main use type of natural grasslands, but it also constitutes a basic measure of grassland management. Insects are important components of biodiversity in grassland ecosystems. However, studies on the effects of grazing on insect diversity are limited. We retrieved all studies on insect diversity with grazing published in the past 40 years from two literature retrieval platforms, i.e., Web of Science and China National Knowledge Infrastructure. We summarized all results of these studies, analyzed the change trends of insect diversity under different grazing conditions and discussed how grazing affects insect diversity. Finally, we suggested the promising research directions in grassland entomology with grazing by considering the paucity of present studies on grazing and insect diversity.
