| 摘 要： | 采用浸叶浸虫法，测定了印楝素与三种杀虫剂对小菜蛾的室内联合毒力作用，并筛选出了药剂的最佳复配比例。结果表明，印楝素：阿维菌素为2．3：1，共毒系数(CTC)为141．14，增效作用最为显著；印楝素：Bt为1：1，共毒系数为136．74；而印楝素与高效氯氰菊酯混配对小菜蛾表现为相加作用。

| Abstract: | The Common-toxicity of azadirachtin with three insecticides were tested in the laboratory by dipping methods.The results showed that azadirachtin with abamectin in mix-proportion of 2.3:1 had remarkable synergistic effects,and common-toxicity cofficient (CTC) was 141.14,and the CTC of the experiment was 136.74.when azadirachtin mixed with Bt in mix-proportion of 1:1.However,The results also indicated that azadirachtin mixed with beta-cypermethrin had no synergistic effect. |
