| 中文摘要: |
| 测试了57种南药植物粗提物对螺旋粉虱成虫的杀虫活性。结果表明，在5 mg/mL浓度下，57种南药植物粗提物对螺旋粉虱成虫表现出较好的触杀活性。其中长春花、艾纳香、刺篱木、薄荷、广藿香、曼陀罗6种南药植物粗提物对成虫的触杀活性在60％以上，活性最好的是长春花粗提物，对成虫的触杀活性为67.3％。毒力测定结果表明：薄荷粗提物对成虫的EC50值最小，为3.308 9 mg/mL。因此薄荷对螺旋粉虱表现出较好的抑制活性，具有进一步研究开发的价值。 |
| 英文摘要: |
| The insecticidal activities of the crude extracts of 57 southern Chinese herbs were tested against the adults of Aleurodicus dispersus. The results showed that there were 6 plant extracts from Catharanthus roseus, Blumea balsamifera, Flacourtia indica, Mentha haplocalyx, Pogostemon cablin and Datura stramonium had >60% insecticidal activities to the adults, especially the crude extracts of C.roseus, the activity of which was 673%. Toxicity test results showed that the EC50 of the crude extracts of M.haplocalyx against the adults was 3308 9 mg/mL. Therefore, the crude extracts of M.haplocalyx showed good inhibitory activity, and had excellent value for further research and development. |
