| Abstract: | 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. |
