Abstract: 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.

Key words: Insect pests, Scale, Hierarchy theory, Pest control strategies
