| 摘 要： | 测定了马缨丹(Lantana camaraL.)地上部位(茎叶花)的不同溶剂提取物及萃取物对黄曲条跳甲Phyllotreta striolata(Fabricius)成虫的取食忌避、拒食、胃毒和触杀作用。结果表明:处理后48 h,以马缨丹乙醇回流提取物效果最好,其对黄曲条跳甲成虫的取食忌避率达94.94%;非选择性拒食率为85.48%;除正丁醇萃取物对黄曲条跳甲成虫的胃毒作用达到56.67%外,其它处理对黄曲条跳甲成虫的胃毒作用不明显;石油醚萃取物、石油醚冷浸物、乙醇回流物对黄曲条跳甲成虫的触杀作用效果最好,分别为56.67,53.33和53.33%。据实验结果可知马缨丹不同溶剂提取物及萃取物对黄曲条跳甲成虫的生物活性主要表现在对成虫较强的忌避和拒食作用。 |

| Abstract: | The deterrent effect,the nonselective antifeedant effect,the oral toxicity,and the contact toxicity of extracts from stems,leaves and flowers of Lantana camara L.to adults of striped flea beetle Phyllotreta striolata were tested.The results showed that the deterrent rates and the antifeedant rates of the ethanol circumfluence extracts from L.camara were 94.94% and 85.48% respectively after 48 h treatment.When the different solvents extracts were applied,the toxicity of the n-Butyl alcohol extract to the adults of striped flea beetle(SFB) was 56.67%,and that of other trials were not significant. |
| Keywords: | Lantana camara extracts Phyllotreta striolata bio-activities effect mode |
