摘　　要：采用浸渍法测定野生与种植伏毛铁棒锤(Aconitum flavum Hand&Mazz)乙醇提取物及生物碱对小菜蛾(Plutella xylostella)的触杀活性。结果表明,野生与种植伏毛铁棒锤30.0 mg/mL乙醇提取物对小菜蛾的72 h校正死亡率分别为86.67%、90.00%,LC50分别为13.14、12.37 mg/mL;野生与种植伏毛铁棒锤生物碱20.0 mg/mL用量时小菜蛾72 h校正死亡率均为90.00%,LC50分别为6.535、6.576 mg/mL。野生与种植伏毛铁棒锤提取物对小菜蛾的触杀活性相近。研究结果可为伏毛铁棒锤这一野生植物资源的有效保护提供一定的依据。The insecticidal activities against Plutella xylostella of ethanol extracts and alkaloid from wild and cultivated Aconi- tum flavum Hand. Mazz were determined by dipping. The results showed that 72 hours after the application the adjusted mortality of the ethanol extracts against Plutella xylostella from wild and cultivated Aconitum flavum Hand. Mazz. were 86.67% and 90.00%（30.0 mg / mL）, respectively. The LC50 were 13.14 mg / mL and 12.37 mg / mL, respectively. The insecticidal activities of alkaloid against Plutella xylostella from wild and cultivated Aconitum flavum Hand. Mazz. were as follows： the adjusted mortality were 90.00%（20.0 mg / mL） 72 hours after the application, and the LC50 were 6.535 mg / mL and 6.576 mg / mL, respectively. It is indicated that the insecticidal activities of wild Aconitum flavum Hand. Mazz. were similar to that of cultivated Aconitum flavum Hand. Mazz.. The result could provide a certain basis for effectively protecting wild plant resources.
