摘要
室内测定结果表明,杀虫剂啶虫咪对苹果绵蚜的天敌日光蜂蛹的羽化率、成虫的死亡率影响很小,对成虫的击倒率也低,属于2级微害产品;毒死蜱对蛹羽化率、成虫死亡率影响大,达到或接近4级有害产品标准;除虫菊和乙酰甲胺磷对日光蜂的毒性介于上述2种农药之间;印楝对蛹的羽化中度有害,但对成虫属微害。防治绵蚜要注意选用对日光蜂等天敌毒性较小的药剂。
The effectiveness of 5 kinds of pesticides on the adults of woolly apple aphid parasite, Aphelinus mali (Hald) were assayed in laboratory. Results showed that the toxicity of Aceptamoprid to the ecdysis of Aphelinus mali (Hald) adults is low, the toxicities of Azadirachtin and Pyrethrins are also low, but Acephate is medium toxic and Chlorpyrifos is high toxic.
