| 摘 要： | 采用常规提取法浸提桃楸树皮的杀虫活性成分。研究结果表明,用质量分数95％乙醇浸提核桃楸树皮,其提取物对舞毒蛾及甘蓝夜蛾幼虫均有较强的胃毒作用和触杀作用。对舞毒蛾的触杀作用强于胃毒作用,对甘蓝夜蛾的触杀作用和胃毒作用无显著差异。施药时间≥4 d、药液浓度≥10 g／L时,对舞毒蛾、甘蓝夜蛾的触杀作用及胃毒作用的平均校正死亡率均超过50％。同时,对舞毒蛾和甘蓝夜蛾的触杀作用及胃毒作用分别进行了校正死亡率-施药浓度毒力分析和死亡率-施药时间毒力分析。 |
| 关 键 词： | 核桃楸树皮 杀虫活性 舞毒蛾 甘蓝夜蛾 |

| Abstract: | The insecticidal components are extracted from bark of Juglans mandshurica Maxim by common extraction method. Results showed that the extract from the bark of J. mandshurica extracted with 95% alcohol has insecticidal activities in stomach poisoning action and contact toxicity to Lymantria dispar L. and Mamestra brassicae L. The stomach poisoning action to L dispar is stronger than contact toxicity, and there is not significant difference between stomach poisoning action and contact toxicity to M. brassicae. The corrected mortality was more than 50% when the extract concentration was above 10 g/L and the insecticide exposure time above 4 d. The relationships between the corrected mortality and extract concentration , insecticide exposure time were analysed in terms of the stomach poisoning action and contact toxicity to L dispar and M. brassicae. |
