用14种农药对温室白粉虱的主要天敌丽蚜小蜂和中华草蛉进行了室内毒力测定。结果表明:灭螨猛对丽蚜小蜂成虫和幼虫在寄主体内的发育、羽化,以及中华草蛉各虫态均无影响。供试的有机磷类和拟除虫菊酯类杀虫剂对丽蚜小蜂有较高的毒性。中华草蛉对有机磷类杀虫剂敏感。大棚中常用的杀菌剂、杀螨剂和选择性杀蚜剂对丽蚜小蜂和中华草蛉均安全。中华草蛉具有天然的抗拟除虫菊酯的能力。
14 kinds of pesticides were used to determine the indoor toxicity of the main natural enemies of the whiteflies, Aphis gossypii and Chrysopa sinica. The results showed that there was no effect on the development and emergence of adults and larvae of the larvae in the host, and on the emergence and emergence of the larvae and the larvae of the larvae. The tested organophosphorus and pyrethroid insecticides were highly toxic to the Aphis gossypii. Chinensis is sensitive to organophosphate insecticides. Commonly used in the greenhouse fungicides, acaricides and selective aphicides Aphid larvae and Chinese weeds are safe. Chinensis has natural resistance to pyrethrins.
