Abstract: Piercing-sucking insects including green leafhopper are the important pest in tea industry. The special way of oviposition and damage of green leafhopper results in that the chemical pesticides were difficult to play their desired role. Tea cultivar resistance, as a part for pset management, gained much attentions and concerns. As the recorder of feeding behaviors of piercing-sucking insects, EPG technique was extensively involved in the cultivar resistance research. Firstly the characteristics of EPG technique were analyzed in present paper, and especially the applications of EPG in the investigation of relationship between the feeding behaviors of Piercing-sucking insects, and the resistance of tea plant to leafhopper were investigated. Furthermore, the paper recorded the feeding process and characteristics of green leafhopper based on the relative results.

Key words: electrical penetration graphs, piercing-sucking insects, tea plant resistance, feeding behavior
