小猿叶甲PhaedonbrassicaeBaly是十字花科蔬菜的重要害虫，现用的防治方法主要是化学防治。为了开发无公害蔬菜工程，本文试用昆虫病原线虫对小猿叶甲幼虫进行敏感性试验，实验表明：小卷蛾线虫SteinernemacarpocapsaeA24对小猿叶甲幼虫颇为敏感，在害虫与线虫数量为1:75时，48小时小猿叶甲幼虫的线虫寄生死亡率达90％以上。经DMRT检验表明：浓度1：100与1：75的寄生死亡率（显著水准0．05和0．01）差异不显著。
Phaeophyceae PhaedonbrassicaeBaly cruciferous vegetables is an important pest, the current prevention and treatment methods are mainly chemical control. In order to develop a pollution-free vegetable project, this paper tried to test the sensitivity of Apis mellifera to the leafhopper larvae. The experiment showed that the Steinernemacarpocapsae A24 was quite sensitive to the larvae of the chyle, and the number of pests and nematodes was 1:75 , The 48-hour-minute aphid larvae nematode parasitic mortality rate of 90%. The DMRT test showed that there was no significant difference in the parasitic mortality rate (significant level 0.05 and 0.01) between 1: 100 and 1:75.
