摘　　要：利用2种苦参碱复配型生物源杀虫剂进行了防治甘蓝小菜蛾效果比较试验。试验结果表明,1%除虫菊素.苦参碱微囊悬浮剂1000倍液具有良好的速效性和防治效果;1%苦参碱.印楝素乳油2000～2500倍液虽然速效性较差,但持效期长,效果良好。两种药剂均对甘蓝无药害,对小菜蛾防效高、毒性小、残留少,适宜在无公害蔬菜生产中推广使用。The control effects of two mixed non-environmental damage pesticides on Plutella xylostella L. were studied, the results showed that 1% pyrethrins-Matrine CS was high efficient and quick-impact, 1% matrine-Azadirachtin EC was slow-effect but persistent and high-effect. They both had no harm on cabbage and high control efficacy on Plutella xylostella L., they are suitable for extending in non-environmental vegetable production.
