Abstract：Since the 1990s, the intensification of agriculture and extensive planting of monocultures has led to a decline landscape biodiversity in farmland, weakening the regulatory role of the natural enemies of agricultural pests. This has resulted in more frequent pest outbreaks, more severe crop damage, and higher pesticide usage. Consequently, the ecological regulation and control of pests has become the focus of increasing research. This review highlights the role of ecological regulation and control of pests in reconstructing farmland landscapes and enhancing the capacity for natural pest suppression. The development of theories of ecological regulation and management of pests (ERMP) in China is outlined, and new methods for analyzing food web relationships are introduced, with emphasis on the research and application of the “field-field edge-landscape” three-dimensional ecological pest control technology based on ERMP. Finally, future directions for ecological pest management technologies are discussed, with the goal of advancing pest control strategies and safeguarding food security and ecological sustainability in China.
