用11种农药对温室自粉虱(Trialeurodes vaporariorum Westw.)进行了室内毒力测定。结果表明:拟除虫菊酯类杀虫剂、灭螨猛对温室白粉虱各虫态毒力均高,并且随虫龄的增加,白粉虱的抗药性增强。稻丰散、乐果、氧化乐果对温室白粉虱若虫毒力尚可,但对其它虫态效果差。马拉硫磷、二嗪农、敌敌畏、洗衣粉除对一龄若虫有一定效果外,对其它虫态毒力极低。北京地区温室白粉虱对某些药剂已出现明显的抗药性。
Indoor toxicity testing of Trialeurodes vaporariorum Westw. With 11 pesticides was conducted. The results showed that the pyrethroid insecticides and offspring mites had high virulence to each species of B. tabaci, and the resistance of B. tabaci was enhanced with the increase of insect population. Toadstool, dimethoate, omethoate on the green house whitefly nymphs virulence is acceptable, but poor on other insect states. Malathion, diazinon, dichlorvos, washing powder in addition to the first instar nymph have a certain effect, very low toxicity to other insect states. Greenhouse whitefly in Beijing has shown some resistance to certain drugs.
