Abstract

This experiment was carried out to evaluate the difference in the biochemical characteristic of the brown planthoppers of the insecticide risistant, susceptible strains and their hybrid progenies. Activity of the esterase isozyme separated by electrophoresis method was remarkably high in the resistant strain as compared with the susceptible strain. Esterase activity between the insecticide-treated strains and the non-insecticide strains was not degraded in the resistant strain and the $F_1$, but remarkably degraded in the susceptible strain. The increase of esterase activity was associated with the development of resistance, and that was inherited with a dominant gene.

본(本) 실험(實驗)은 벼멸구에 대한 반수치사약량(半數致死藥量)의 차이(差異)를 나타내는 저항성(抵抗性) 및 감수성계통(感受性系統)과 그들의 교잡종(交雜種) $F_1$에 대(對)한 생화학적(生化學的) 특성(特性)을 구명(究明)하고자 실시(實施)하였다. 살충제무처리(殺蟲劑無處理)의 esterase활성(活性)은 저항성계통(抵抗性系統)과 교잡종(交雜種) $F_1$이 감수성계통(感受性系統)에 비(比)하여 높았으며, diazinon, MEP, BPMC 처리후(處理後) esterase의 활성변화(活性變化)는 저항성계통(抵抗性系統)과 교잡종(交雜種) $F_1$에서는 별차이(別差異)가 없었으나 감수성계통(感受性系統)에서는 현저(顯著)히 떨어졌다. Esterase의 높은 활성(活性)은 저항성발달(抵抗性發達)과 관계(關係)가 있었으며 교잡종(交雜種) $F_1$에서 esterase 활성(活性)이 높게 나타난 것은 저항성계통(抵抗性系統)이 우성인자(優性因子)로 유전(遺傳)됨을 알 수 있었다.
