摘　　要：刺探电位图谱(EPG)技术是用来记录刺吸式口器昆虫口针在寄主组织中刺探行为的电信号变化特征的技术,主要用于昆虫刺探(取食)、传毒行为,植物抗虫机制等的研究,本文对其发展历史、基本原理、波形特征和生物学意义进行了综述,并讨论了该技术目前存在的问题及应用前景。Electrical penetration graph （EPG） is a technique that can record the bioelectrical signal movement characterized by the mouthpart behavior of piercing-sucking mouthpart insects in different tissues of host plants. It is employed to study the penetration （feeding） behavior and virus-transmission behavior of herbivorous piercing-sucking mouthpart insects as well as the resistance mechanisms of host plants to insects and the bioelectrieal response of host plants that are penetrated by herbivorous piercing sucking mouthpart insects. This paper summarizes the develop ment history, rationale, wave pattern features and biological significance of EPG technique, The problems and pros- pects for future applications of EPG are also discussed.
