摘　　要：为评估惰性粉对菜豆象的防治效果,本文在不同浓度、时间和温度条件下,测定了3种惰性粉对菜豆象的致死作用。结果表明:"粮之宝"食品级惰性粉在用量为20 mg/kg处理72 h或40 mg/kg处理48 h时,均能使菜豆象成虫死亡率达到100%;环境温度为25℃时,食品级惰性粉杀死菜豆象的用量明显降低。惰性粉对菜豆象成虫和卵的防治效果比对菜豆象低龄幼虫、高龄幼虫和蛹的防治效果好。In order to evaluate the control efficiency of inert powder on the bean weevil（Acanthoscelides obtectus（Say））,three different powders were tested against A. obtectus under the conditions of different concentration,time and temperature. The results indicated that when the inert powder treated on A. obtectus with a dosage of 20 mg/kg for 72 hours or 40 mg/kg for 48 hours,the mortality of A. obtectus adult reached 100%. A. obtectus could be killed with a low dosage of inert powder at 25℃. The control efficiency of inert powder on adults and eggs was better than that of lower instar larvae,higher instar larvae and pupae.
