甘蓝蚜虫Brevicoryne brassicae(L.)(半翅目：姬蜂科)是巴基斯坦十字花科植物的重要害虫。在发生推荐杀虫剂防治效果不佳的事件后，本研究旨在了解巴基斯坦油菜夜蛾的抗药性状况。2006年至2010年，采用成虫浸泡法对无翅目成虫对12种杀虫剂的反应进行了生物测定。未发现对硫丹的抗性或对硫丹的抗性水平很低；有机磷：毒死蜱和丙溴磷。对灭多威；甲氨基阿维菌素苯甲酸酯；拟除虫菊酯：氯氰菊酯、溴氰菊酯、联苯菊酯和溴氰菊酯；以及新烟碱类：吡虫啉、扑热息痛和甲胺磷的抗药性；随着它们在蔬菜上的常规使用，抗药性逐渐增加。甘蓝型油菜对这两种杀虫剂的抗性在2007年和2008年保持在很低到很低的水平，但在2009年(除氯氰菊酯和联苯菊酯外)和2010年增加到中等到高度水平。在为害严重的情况下，建议轮用无抗药性、极低抗药性和低抗药性的杀虫剂。
Cabbage aphid Brevicoryne brassicae (L.) (Hemiptera: Aphididae) is a serious pest of crucifers in Pakistan. After incidences of poor control by recommended insecticides, the current study was undertaken to find out the status of insecticide resistance in Pakistani B. brassicae. Apterous adult aphids were bioassayed from 2006 to 2010 for their response to 12 insecticides using an adult immersion method. No or very low levels of resistance was found to endosulfan; and the organophosphates: chlorpyrifos and profenofos. Resistance to methomyl; emamectin benzoate; the pyrethroids: cypermethrin, lambdacyhalothrin, bifenthrin and deltamethrin; and the neonicotinoids: imidacloprid, acetamiprid, and thiamethoxam; increased progressively in concurrence with their regular use on vegetables. B. brassicae resistance to these insecticides remained very low to low in 2007 and 2008, but then it increased to moderate to high levels in 2009 (except cypermethrin and bifenthrin) and 2010. Under heavy infestations of this aphid, the application of insecticides having no, very low and low resistance is recommended in rotation.
