茚虫威等4种杀虫剂对意大利蜜蜂急性毒性研究

The Acute Toxicity of 4 Insecticides Containing Indoxacarb to Apis mellifera

为了评价不同作用机制杀虫剂对意大利蜜蜂的急性毒性,分别采用摄入法和触杀法测定了茚虫威等4种杀虫剂对蜜蜂的急性经口毒性和接触毒性。结果表明,对蜜蜂的经口毒性大小为茚虫威<啶虫脒<噻虫嗪<甲维盐,其中茚虫威对蜜蜂的经口毒性为中毒,啶虫脒为高毒,噻虫嗪和甲维盐为剧毒;对蜜蜂的接触毒性大小为甲维盐<啶虫脒<茚虫威<噻虫嗪,其中甲维盐、啶虫脒和茚虫威对蜜蜂的接触毒性为高毒,噻虫嗪为剧毒。

In order to evaluate the acute toxicity of different mechanism insecticides to Apis mellifera, contact method and oral method were respectively used to measure the acute toxicity of four insecticides containing indoxacarb to Apis mellifera in the laboratory. The results showed that the oral toxicity to Apis mellifera was indoxacarb 〈acetamiprid 〈 thiamethoxam 〈emamectin benzoate. The oral toxicity of indoxacarb to Apis mellifera was moderately toxicity while acetamiprid as higher toxicity, thiamethoxam and emamectin benzoate were highly toxic; the contact toxicity to Apis mellifera was emamectin benzoate〈acetamipri , the contact toxicity of emamectin benzoate, aeetamiprid and indoxcacarb to Apis meUifera was higher toxic, thiamethoxam was highly toxic
