摘　　要：小猿叶甲是十字花科蔬菜重要害虫,以幼虫和成虫取食植株叶片为害。近年来,小猿叶甲的发生越来越严重,其防控以化学防治为主,但市场上暂未有登记用于防治小猿叶甲的农药产品,为此,对防治小猿叶甲的杀虫剂进行了筛选试验。结果表明:苦参碱、阿维菌素对小猿叶甲3日龄幼虫和5日龄幼虫防治效果均较好,而烯啶虫胺和呋虫胺对小猿叶甲低龄幼虫具有一定的防治效果,防治小猿叶甲成虫,阿维菌素和烯啶虫胺的效果相对较好。说明苦参碱、阿维菌素、烯啶虫胺和呋虫胺这4种药剂可用于防治小猿叶甲。Phaedon brassicae is an important pest of cruciferous vegetables,which cause damage by larvae and adults feeding on the leaves of plants.In recent years,the occurrence of Phaedon brassicae has become more and more serious,and the prevention and control of Phaedon brassicae is still dominated by chemical control,but there are no pesticide products registered for the control of Phaedon brassicae.Therefore,the screening test of insecticides to control Phaedon brassicae was carried out.The results showed that:matrine and avermectin had good control effects on 3-day-old larvae and 5-day-old larvae,nitenpyram and dinotefuran had certain effects on young larvae,and avermectin and nitenpyram had relatively better control effects on the adults of Phaedon brassicae.The results showed that matrine,avermectin,nitenpyram and dinotefuran could be used to control Phaedon brassicae.
