| 摘 要： | 探讨了鸦胆子提取物对斜纹夜蛾3龄和5龄幼虫的拒食活性。结果表明,鸦胆子提取物对斜纹夜蛾幼虫具有较好的拒食活性。当浓度为0.5mg/mL时,对斜纹夜蛾3龄、5龄幼虫的拒食活性稍强于0.1mg/mL印楝素的拒食活性;24h的拒食活性测定中,3龄和5龄幼虫的非选择性AFC50分别为0.0374mg/mL和0.0370mg/mL;选择性AFC50分别为0.0320mg/mL和0.0230mg/mL,具有进一步研究开发的价值。

| Abstract: | The antifeedant activities of extracts of Brucea javanica(L.) Merr against Spodoptera litura Fabricius larvae were tested.The results showed that the extracts had preferable antifeedant activities against the 3th instar and 5th instar larvae when the concentration reached 0.5 mg/mL.The non-selective AFC50 for the 3th instar and 5th instar larvae were 0.037 4mg/mL and 0.037 0 mg/ml after treated for 24 hours.The selective AFC50 were 0.032 0 mg/mL and 0.023 0 mg/mL,respectively. |
