Study Methods of Plant Tolerance to Insect Pests
植物耐虫性的研究方法

This paper reviews methods for studying the plant tolerance to insect pests, including functional plant loss index (FPLI), tolerance index, yield loss, damage and survival proportion of plants, root volume (damage), dry weight of plants and insects, characteristics of chlorophyll fluorescence, sap amounts of the main shoot and activities of protective enzymes in the body of plants, and population development and feeding behaviors of insects. Future prospects of research in this field are discussed.
