摘　　要：小菜蛾是蔬菜重点害虫之一,长期药剂防治可能会使其产生抗性。为筛选出防治甘蓝小菜蛾的理想药剂,以“京丰”为供试蔬菜品种,比较研究10%虫螨腈悬浮液、2.5%阿维菌素·氟铃脲和2%阿维·高氯杀虫剂对该害虫的防治效果。结果表明,在小菜蛾幼虫2~3龄前,3种方式对小菜蛾均有良好的控制效果,药后10 d均能有效控制小菜蛾为害,而且无药害现象。该试验为相关地区防治小菜蛾提供参考。Plutella xylostella is one of the key vegetable pests,and long-term chemical control may lead to resistance.In order to screen for ideal pesticides for controlling cabbage Plutella xylostella,“Jingfeng”was used as the test vegetable variety,the control effects of 10%Chlorfenapyr suspension,2.5%Avermectin·Fluazuron,and 2%Avermectin·High chlorine insecticides on Plutella xylostella were compared.The results showed that before the 2-3 instars of Plutella xylostella larvae,all three methods had good control effects on Plutella xylostella.After 10 days of treatment,all methods were effective in controlling Plutella xylostella damage,and there was no phenomenon of drug damage.This experiment provided a reference for the prevention and control of Plutellaxylostella damage in relevant regions.
