| 摘 要： | 为评价印楝素对仓储害虫米蛾的毒效,采用微量点滴法,比较印楝素与溴氰菊酯对米蛾的室内毒力。结果表明:印楝素对米蛾的毒力随着处理时间的延长而增强,随处理时间的延长溴氰菊酯对米蛾的毒力差异不显著,说明印楝素对米蛾的作用效果较慢,药效持续时间长,适合应用于仓储害虫的防治。

| Abstract: | In order to evaluate the toxicity of azadirachtin on storage pests Corcyra cephalonica,the toxicity of azadirachtin was compared with deltamethrin on Corcyra cephalonica by micro drop method.The results showed that the toxicity of azadirachtin was increased with the extension of processing time,toxicity of deltamethrin on Corcyra cephalonica had no significant difference with processing time.It showed that the effect time of azadirachtin was slower,but longer efficacy,it was suitable for storage pest control. |
