摘　　要：采用药膜法和玻片浸渍法分别测定了14种常用杀虫杀螨剂对腐食酪螨雌成螨和卵的毒力。结果表明:各药剂对雌成螨都有一定作用,但对卵没有杀伤效果。其中,对雌成螨毒力最高的为杀螨多,LC50为0.2568 mg.L-1;毒力最低的为敌敌畏,LC50为320.4793 mg.L-1。The toxicity of fourteen insecticides/acaficides to Tyrophagus putrescentiae was studied using dry residual film method. The results showed that all insecticides/acaricides were effective against adult females. The most effective insecticide was abamectin （LC50 = 0.2568 mg · L^-1） and the least effective one was＇ dichlorovos （LC50 = 320. 4793 mg· L^-1）. However, these insecticides/acaricides had no effect against eggs.
