Abstract:The effective utilization of biodiversity for sustainable development and conservation is a universal concern. In recent years, ecological pest management has become a hot topic at home and abroad because it can improve biodiversity and enhance ecosystem services through biological control in agroecosystems. This paper presents an overview of the progress and practice of rational utilization of biodiversity to enhance pest control, and future prospects for this approach, based on achievements in China and other countries. We first describe the basic concept of biodiversity and its association with integrated pest management, then introduce theoretical hypotheses on utilizing biodiversity to control crop pests (including the natural enemy, resource concentration, associational resistance, “push-pull”, moderate complexity and landscape buffer, hypotheses. Finally, we provide an overview of the practical application of improving biodiversity to support pest control, focusing on some previously reported examples in China to reflect contributions made by Chinese entomologists. Given that modern agricultural intensification has increasingly led to the simplification of agroecosystems and a decline in biodiversity, we discuss in some detail the potential for facilitating both theoretical research and the practical application of biodiversity to further improve landscape level pest control.
