【背景】薇甘菊为危险性入侵植物；同时椰子坚蚜为椰子上的重要害虫,对其防治方面的研究较少。研究薇甘菊次生物质对椰子坚蚜的生物活性可为薇甘菊的综合利用及椰子坚蚜的防治提供参考。【方法】采用室内生物测定的方法研究了薇甘菊4种溶剂提取物对椰子坚蚜的胃毒和触杀活性。【结果】供试的4种提取物中,正丁醇提取物和丙酮提取物对椰子坚蚜的胃毒水平较高,LC50分别为12.93和12.48 mg·mL-1,显著高于环己烷提取物和石油醚提取物。而4种提取物对椰子坚蚜的触杀毒力差异不显著,环己烷提取物、正丁醇提取物、丙酮提取物和石油醚提取物对椰子坚蚜的LC50分别为15.28、12.28、11.40和16.62 mg·mL-1。【结论与意义】薇甘菊提取物在椰子坚蚜防控中具有一定的应用潜力。

Background]Mikania micrantha is the invasive plant and Cerataphis lataniae is the important pest in coconut palm, the research on control of C. lataniae was seldom carried, so the research on the biological activity of M. micrantha secondary com-pounds on Cerataphis lataniae may provide reference for the use of M. micrantha and control of C. lataniae. [Method]The stomach and contact toxicities of M. micrantha extracts from 4 solvents ( cyclohexane, n-butanol, acetone, petroleum ether) were studied.[Result]N-butanol and acetone extracts showed higher activities than cyclohexane or petroleum ether extracts in contact toxicity, and the LC50 values were 12.96 mg·mL-1 and 12.48 mg·mL-1 , respectively. No significant differences were found among the con-tact toxicities of 4 M. micrantha extracts to C. lataniae, and the LC50 of cyclohexane extract, n-butanol extract, acetone extract and petroleum ether extract of M. micrantha were 15.28 mg·mL-1 , 12.28 mg·mL-1 , 11.40 mg·mL-1 and 16.62 mg·mL-1 , respec-tively. [Conclusion and significance]M. micrantha extracts have potential to control C. lataniae.
