Abstract:
Sustainable pest management is one of the most important issues in agricultural ecology and is essential to food security. Consequently, the development of environmentally friendly, sustainable, and effective, strategies to manage pest populations has been a focus of research over the past decade. Research in this field has, however, been hindered by the absence of a theoretical framework for ecologically based pest management. In this paper, we discuss the ecological threshold and efficiency of ecologically based pest management, and construct a series of ecological indices for the ecological threshold. We also summarize several relevant theoretical issues, including the population model, food web structure, spatial scale and ecological energy. Finally, we discuss the future of pest control with the goal of promoting the theoretical development of ecologically based pest management.
