| Abstract: | The contact poisoning and antifeedants effect of extract of Cinnamomum camphora and Artemisia annua against cabbage worn were studied. The result showed that the activity of extract of C. camphora-alcohol and A. annua-petroleum ether are better. Forty eight hours after experiment, the rates of antifeedants are 72.11 % and 57.86 %,and medium lethal concentrations of contact poisoning are 1.232 and 1.275 g·L -1 respectively. |
