Abstract: In the past decade, the regional distribution and ecologically based pest management (EBPM) of pest populations have become a hot topic in integrated pest management (IPM). Although EBPM techniques have been successfully applied in the field level to control many agricultural pests with sustainable and green characteristics, the systematic strategies of EBPM from field level to regional scale still lack. In order to solve regional EBPM of agricultural pests, we summarized the landscape characteristics of pest population, including regional distribution, heterogeneity, diffusivity, outbreak, and synergy. Then, we clarified the systematic strategies of regional EBPM, which included preventive management, targeted management and post-outbreak control. A regional strategy of prevention, management, and control would be effective to suppress outbreak of agricultural pests. Finally, we summarized the advantage of regional EBPM in the future, which emphasize safety, efficiency, precision and sustainability of insect pest management. Therefore, the regional EBPM is an inevitable choice to ensure the ecological security and agricultural food production in the future.
