| 摘 要： | 采用冷浸法和超声波提取法对海杧果(Cerbera manghas L.)叶进行提取。测定了其对斜纹夜蛾［Spodoptera litura (Fabricius)］的毒杀和拒食活性。浸渍法试验结果表明，处理48 h后，乙酸乙酯萃取相对斜纹夜蛾的毒杀活性最高，LC50为1.277 3 mg/mL；采用叶碟法进行非选择性和选择性拒食活性测定，乙酸乙酯萃取相处理24 h后，拒食率分别为43.39%和42.55%。

| Abstract: | Poisonous and antifeedant activities of the leaves of Cerbera manghas to Spodoptera litura (Fabricius) were studied by means of soaking and ultrasonic extraction. The results showed that the poisonous activity of ethyl acetate against S. litura was the best, and the LC50 was 1.277 3 mg/mL after 48 hours by immersion method, while the antifeedant rates were 43.39% and 42.55%, respectively, after 24 hours by ethyl acetate by leaf disc tests. |
