| 摘 要： | 测试了19种植物提取物及活性组分对褐飞虱的产卵忌避活性。结果表明,在10mg/mL浓度下处理24h,对褐飞虱产卵忌避达70%以上的有断肠草(枝叶)、红楝子(枝叶)和鸦胆子(果实);其余16种植物提取物对褐飞虱的产卵忌避率均在70%以下。活性组分24h生测结果显示,红楝子的氯仿萃取物和乙酸乙酯萃取物的产卵忌避率分别达98.17%和88.70%;断肠草的氯仿萃取物和正丁醇萃取物产卵忌避率分别为90.26%和63.19%;鸦胆子的脂溶部分产卵忌避率达86.00%,其他活性组分的产卵忌避率均低于65%。 |

| Abstract: | Extracts of 19 plant species were tested for oviposition deterrent activities against Nilaparvata lugens Stal.The results showed that,after 24h treated with 10mg/mL concentration,oviposition deterrent indices(ODI) of extracts of Gelsemium elegans Benth(leaf),Toona sureni(Bl.) Merr(leaf) and Brucea javanica(L.) Merr(fruit) possessed over 70%.The ODI of the rest extracts possessed fewer than 70%.The active components were tested by the bioassay.The results after 24h treatments indicated that the ODI of extracts of Toona sureni(Bl.)Merr(leaf) by chloroform and ethyl acetate were 98.17% and 88.70%,respectively.Extracts of Gelsemium elegans Benth(leaf) by chloroform and butanol were 90.26% and 63.19%,respectively.Extracts of Brucea javanica(L.) Merr(fruit) by liposolubility reached 86%.The other extracts of the active components were lower than 65%. |
