商陆等6种药用植物粗提物对扶芳藤稠李巢蛾的杀虫活性

室内测定6种药用植物粗提物对稠李巢蛾（Yponomeutidae evonymellus L.）的生物活性，结果表明：商陆（Phytolacca acinosa Roxb.）根的水提物较之其它五种药用植物具有较好的杀虫活性，其胃毒活性在72h后校正死亡率为72.73%，生长抑制活性72h后抑制率为72.08%，此外还具有一定的触杀活性。6种药用植物种中商陆具研究开发潜力。

The Insectici Activities of Crude Extracts from 6 Medicine Plants Against the Larvae of Yponomeutidae evonymellus L.

Six medicine plants crude extracts were used to test the insectici activities against the larvae of Yponomeutidae evonymellus L.in laboratory.The results showed that the insectici activities of the extracts from roof of Phytolacca acinosa Roxb.was higher than other plants'.The stomach toxicity of Phytolacca acinosa Roxb.against the larvae of Yponomeutidae evonymellus L.reached 72.73% within 72h,and the growth inhibition rate was 72.08%.The result also showed that the extract of Yponomeutidae evonymellus L also had some contact toxicity against the larvae.All results indicated that Yponomeutidae evonymellus L was worth to study and exploit.
