摘要
1990～1991年对贵阳、合肥、安顺、都匀、铜仁、毕节等5市1县甘蓝上的菜青虫进行了抗药性调查。用7种常用农药以点滴法测定菜青虫五龄幼虫的LD_(50)值,结果表明:各地菜青虫对敌敌畏和溴氰菊酯(敌杀死)已普遍产生抗药性。抗敌敌畏的菜青虫种群对有机磷农药(马拉硫磷、杀螟松)、菊酯农药(溴氰菊酯、氯氰菊酯、二氯苯醚菊酯)和杀虫双有交互抗性;抗溴氰菊酯的菜青虫种群对菊酯农药(氯氰菊酯、二氯苯醚菊酯)有交互抗性。各地菜青虫对杀虫双仍有较高的敏感性,还没有明显的抗药性。
An inestigation on resistance of cabbge worm to insecticides in cabbge field of 5 cities and 1 county in Guizhou province had been carried out during 1990?1991. The results obtained were as follows: All cabbage worm of 6 districts showed resistance to deltamethrin and rtdichlorvos. The cabbge worm which is resistant to rtdichlorvos showed positive cross-resistance to malathion, fenitrothion, deltamethrin, cypermethrin, permethrin and dimehypo. The cabbge worm which is resistant to deltamethrin showed positive cross-resistance to cypermethrin and permethrin and negative cross-resistance to rtdichlorvos, malathion, fenitrothion and dimehypo.
