摘　　要：菜青虫是十字花科蔬菜上的重要害虫,严重影响蔬菜的产量和品质,每年都造成重大经济损失。利用喷雾法测试了一种高效氯氰菊酯微囊悬浮剂对菜青虫的药效。结果表明:该药在其有效成分22.50~33.75 g/hm^(2)范围内,施药后2 d、5 d、10 d对甘蓝菜青虫的防效分别为86.37%~93.89%、90.80%~95.80%、86.03%~91.40%。说明其对甘蓝菜青虫具较好的防效,且持效期较长,具有良好的生产应用价值。故推荐采用其有效成分22.5~33.75 g/hm^(2)在生产上防治甘蓝菜青虫的危害,且菜粉蝶卵孵化盛期至菜青虫1、2龄高峰期为最佳施药防治时期。Pieris rapae(Linnaeus)is an important pest on cruciferous vegetables,which seriously affects the yield and quality of vegetables and causes great economic losses every year.In this experiment,the efficacy of a beta-cypermethrin microcapsule CS against Pieris rapae was tested by spray method.The results showed that within the range of 22.5~33.75 g/hm^(2),the control effects of the pesticide were 86.37%~93.89%,90.80%~95.80%and 86.03%~91.40%after 2 d,5 d and 10 d,respectively.The results showed that it had a good control effect on Pieris rapae(Linnaeus),and had a long-lasting period,so it had good production and application value.22.5~33.75 g/hm^(2) of its effective component is recommended to control the damage of Pieris rapae(Linnaeus)in production,and the best time to control Pieris rapae(Linnaeus)is from the peak of egg hatching to the peak of 1st and 2nd Instar.
