| 摘 要： | 为了寻求新型植物源杀虫剂,本试验以棉铃虫为试虫,采用饲料混毒法对何首乌、桂皮和花椒3种植物干粉及何首乌不同溶剂提取物进行了生物活性测定.结果表明:3种植物干粉对棉铃虫的生长抑制率由高到低依次为:何首乌＞桂皮＞花椒;用何首乌干粉处理饲料进行饲喂(第5天不换饲料),试虫则一直处于幼虫状态直至死亡.70％乙醇粗提物和水粗提物...

| Abstract: | In order to find the latest botanical insecticides,the growth and development effect of three plants powders and different solvent extracts of Polygonum multiflorum on the H.armigera were tested by diet-incorporated method in this article.The results showed that the inhibitory rate of growth was P.multiflorum>Cassia bark>Zanthoxylum bungeanumm Maxim.The H.armigera all died in the laval stage if the treatment diet of P.multiflorum powders did not renew with the normal diet in the 5th day.The 70% Ethanol extracts and the water extracts had strong inhibition of growth on the H.armigera and the inhibitory rate of weight was 78.9% and 80.4% in the 5th day,respectively. |
