摘　　要：在蔬菜田对不同生物防治技术组合对叶菜害虫的控制作用及其生态、经济效益进行了研究和分析,结果表明:生物防治技术组合对菜心和芥蓝害虫的防治效果比以化学农药为主的防治效果更好,能显著增加田间天敌密度,并能明显提高经济效益。This paper studied the effect of biological control-based integrated management on the major pests of leafy vegetables and analyzed its eco-economic benefits based on field experiments.The results showed that in Chinese cabbage and Chinese kale fields,a set of biological control measures decreased pest densities lower than those by chemical control measures,increased natural enemy abundance,and also had good economic returns.
