采用叶碟法测定了45种南药植物粗提物对斜纹夜蛾3龄幼虫的拒食活性。结果表明,斜纹夜蛾3龄幼虫对九里香、鸭胆子、槟榔、薏苡、花椒、胡椒、生姜的非选择性拒食率均达75%以上,对九里香、生姜、地桃花、竹卷心、苏铁、槟榔、蟛萁菊的选择性拒食率均达90%以上,其中对九里香的拒食率为100%。

The antifeedant activity of 45 kinds of crude extracts of Southern medicine on 3rd instar larvae of Spodoptera litura was determined by leaf disc method. The results showed that the non-selective antifeedant rate of the third instar larvae of Spodoptera litura was more than 75% for Jiuliang, Dujiaozi, Areca, Coix, pepper, ginger and ginger, The selective antifeedant rates of cycads, betel nuts and gall peels reached more than 90%, among which the antifeedant rate against Jiulixiang was 100%.
