摘　　要：尺度已成为生态学上的一个重要概念和研究热点 ,但在害虫防治中尚未引起足够的重视 .本文从生态学尺度概念和等级理论出发 ,分析了不同尺度水平上害虫研究的方法、内容、关键问题及研究成果对害虫防治的意义 .在对害虫发生为害特征、害虫种群动力学原理、农业生态系统结构的演变、害虫防治的社会化、害虫防治技术的发展等因素的分析的基础上 ,指出害虫防治策略在时空尺度上拓展的趋势和必要性 .Scale is becoming an important concept in ecology and a focus in ecological research. However, it is not the case in insect pests research and control. Based on the concept of scale and hierarchy theory, the authors analyzed the methodologies, contents and key problems to be specially solved in insect pests research on different levels of scale, and the implications of research results on pest control. Through the analyses of the occurrence and injury characteristics of insect pests, their population kinetics, succession of agro ecosystem structure, socialization of pest control and development in pest control technologies, the authors pointed out the trend and necessity of the enlargement of temporal and spatial scales in pest control strategies.
