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.%以假眼小绿叶蝉为主的茶园刺吸式昆虫是茶叶生产中的重要害虫,其特殊的产卵习性和危害方式使化学农药很难发挥理想的作用.茶树品种抗虫性研究作为控制刺吸式害虫的一种新途径,引起了科研工作者的关注和重视.而昆虫刺探电位图谱(Electrical Penetration Graph,EPG)技术,作为刺吸式口器昆虫的取食行为记录仪,参与到这一研究,明确了许多叶蝉行为和品种抗虫性间的关系.本文在分析EPG技术特点的基础上,总结了EPG技术在茶园刺吸式害虫的取食行为、茶树品种抗虫性的检测和抗性机理方面的应用,并且对相关研究结果进行梳理,归纳出假眼小绿叶蝉的取食过程和特点.
