摘　　要：以氟酰脲悬浮剂、茚虫威乳油、乙基多杀菌素悬浮剂为对照,比较了不同用量氟酰脲·茚虫威悬浮剂对甘蓝小菜蛾的防治效果。试验结果表明,28%氟酰脲·茚虫威悬浮剂38.4、48.0 g/hm2处理对甘蓝小菜蛾均具有良好的防治效果,药后3 d防效最高,分别为82.24%和87.16%,持效期7 d左右。因此,28%氟酰脲·茚虫威悬浮剂可作为防治甘蓝小菜蛾的药剂,建议与其他农药进行合理轮用。In this study,we tested the control efficacy of different dosages of 28%flufenuron indoxacarb SC(suspension concentrate)on Plutella xylostella in cabbage,by taking flufenuron SC,indoxacarb EC(emulsifiable concentrate)and spinetoram SC as control treatments.The results showed that the two treatments of 28%flufenuron indoxacarb SC(with dosages of 38.4 and 48.0 g/hm2)both showed good control efficiency against P.xylostella,and the control efficiency was the highest after 3 days of the insecticides application,with the control efficiency of 82.24%and 87.16%,respectively.Meanwhile,the lasting effect period was about 7 days.Therefore,28%flufenuron indoxacarb SC is an ideal insecticide for controlling P.xylostella in cabbage,and it is suggested to be used in rotation with other pesticides.
