Abstract: At present, in the context of protecting biodiversity, maintaining the sustainable and healthy development of ecosystems and reducing the use of fertilizers and pesticides, using agricultural biodiversity to control pests has become one of the hotspots in domestic and foreign research. Agricultural biodiversity is important for maintaining the function of agricultural ecosystem and the control of crop pests are of great significance. This paper briefly describes the concept and current situation of agricultural biodiversity, and summarizes the scientific principles or theories of pest ecological regulation of biodiversity, starting from the protection of agricultural biodiversity by non-agricultural habitats and its influencing factors on agricultural biodiversity. The methods and specific applications of ecological regulation to crop pests using agricultural biodiversity are analyzed at the three levels of farmland, farmland boundary and farmland landscape pattern, and finally put forward the development direction of ecological regulation to crop pests using agricultural biodiversity, which provides knowledge, principles, methods and technical support for effective pest ecological regulation.

Key words: landscape, non-agricultural habitat, plant diversity, ecological control, pests
