中文摘要：[目的]研究商陆、狗尾草、紫花地丁3种植物提取物对菜粉蝶的拒食作用。[方法]采用丙酮冷浸法对商陆、狗尾草、紫花地丁3种植物的活性成分进行提取,并利用小叶碟添加法测定各提取物对菜粉蝶幼虫的非选择性拒食活性。[结果]3种植物中,商陆丙酮浸出液对菜粉蝶的拒食作用效果最好,24、48h拒食率分别为74.53%和82.34%;商陆提取物对菜粉蝶3龄幼虫的拒食效果随其浓度增加而增大,0.050g/ml处理的拒食率为最高,24、48h拒食率分别为74.53%和82.34%。[结论]商陆可作为潜在植物源杀虫剂以供研究和利用。

外文摘要：[Objective] The research aimed to study antifeedant activity of Phytolacca acinosa Roxb., Setaria viridis （L.） Beauv and Viola yedoensis Makino extracts against Pieris rapae. [Method] Activity material was extracted from S. viridis （L.）, P. acinosa and V. yedoensis using acetone cold soak method, and non-selective antifeedant activity of extracts to Pieris rapae larva was determined by using lobular plate addition method. [Result] The results showed that the acetone leaching agent of P. acinosa had most obvious antifeedant effects on Pieris rapae. The antifeedant rate were 74.53% and 82.34% at 24 and 48 h respectively. With the concentration increasing, the antifeedant effect of P. acinosa extracts increased. The antifeedant rate of 0.050 g/ml treatment was the highest, being 74.53% and 82.34% at 24 and 48 h. [Conclusion] P. acinosa could be studied and utilized as potential botanical insecticide.
