摘要
灰翅夜蛾Spodopteramauritia是危害草坪的重要害虫。药剂测定试验表明 ,抑太保、氯氰菊酯、灭多威等药剂对灰翅夜蛾有较高毒力 ,对 3龄初幼虫的LC50 为 0 4 895～ 2 3672mg L。 4龄以上害虫耐药性显著增强。
Spodoptera mauritia is an insect pest that damages lawns. Some insecticides such as Chlorfluazuron, Cypermethrin and Methomyl were effective in controlling this pest in experimental trials, with LC 50 ranging from 0.4895 to 2 3672 mg/L in the early 3rd instar larvae. Insecticide resistance developed quickly after the 4th instar larvae.
