刺探电位图谱(EPG)技术的应用综述

Electrical penetration graph (EPG) is a technique that could be mark the bioelectrical signal movement characteristic of the mouthparts behavior of piercing-sucking mouthparts insect in different organize of post plant. It is applied to study for what plant resistance mechanism, bioelectrical response of host plant when they been penetrating, transfer virus behavior, penetration (feeding, harm) behavior and biology, ecology, bioassay of pesticide about herbivorous piercing-sucking mouthparts insect, chemical ecology, and also be applied to study plant electrophysiology. This paper summarizes these. The question and prospect about EPG technique also being discuss.
