| 摘 要： | 探讨钩枝藤总生物碱及3个单体化合物(1)Ancistrocline，(2)5′-O-demethylhamatintine，(3)N-methylphylline]对斜纹夜蛾幼虫的毒杀活性，旨在开发新型植物源农药。采用浸虫法测定钩枝藤总碱对斜纹夜蛾3龄幼虫的毒杀活性和采用饲料混毒法测定钩枝藤单体化合物对斜纹夜蛾初孵幼虫毒杀活性。结果表明：钩枝藤总碱对斜纹夜蛾3龄幼虫具有较强的毒杀作用，其第3天和第5天的LC50值分别为2.61 mg/mL和0.91 mg/mL。单体化合物对斜纹夜蛾初孵幼虫具有明显的抑制生长发育作用，其中以化合物(2)抑制作用最强，主要表现为化蛹率（23.33％）、羽化率（13.33％）显著低于对照（化蛹率90.00％、羽化率86.67％）。
