摘  要:
研究了磷化氢(PH3)对赤拟谷盗成虫的半数击倒时间NT50与致死中量LC50的关系,证明NT50≥30min的赤拟谷盗时PH3具有抗性,证明NT50与LC50、NT100与LC99.9之间均存在线性关系并分别求出了回归方程。同时,利用该方法测定了4个赤拟谷盗品系对PH3的抗性系数。

摘  要:
The relationship between NT50(narcosis time) and LC50 of phosphine to four strains ofTribolium cstaneum was studied. It found that T. castaneum (NT≥30min) was resistanceto phosphine, and there was a positive linear correlation between NT50 and LC50, NT100 andLC90.0, respectively, and the regressive equations were obtained respectivlly. The Rf value offour strains of T. castaneum to phosphine were measured by the method.
