| 摘 要： | 为了探讨亚致死浓度氯虫苯甲酰胺对甜菜夜蛾(Spodoptera exigua)生长发育及解毒酶活性的影响,采用饲料混毒生物测定法,确定氯虫苯甲酰胺对甜菜夜蛾3龄幼虫的亚致死剂量(LC25和LC50),并研究其对甜菜夜蛾的亚致死效应。结果表明:与对照相比,亚致死浓度的氯虫苯甲酰胺处理后,甜菜夜蛾幼虫历期和蛹期显著延长,幼虫体重和蛹重显著减轻,羽化率、单雌产卵量和下一代卵的孵化率均下降,说明亚致死浓度氯虫苯甲酰胺对甜菜夜蛾种群增长有一定的抑制作用。亚致死浓度的氯虫苯甲酰胺处理甜菜夜蛾3龄幼虫后,其体内的酯酶和多功能氧化酶活性均显著低于对照,表明亚致死浓度的氯虫苯甲酰胺对甜菜夜蛾的酯酶和多功能氧化酶活性具有一定的抑制作用。这些结果证明,亚致死剂量氯虫苯甲酰胺导致甜菜夜蛾幼虫体内酯酶和多功能氧化酶活性的下降可以在一定程度上说明其种群生命参数的变化。此外,在亚致死剂量下,氯虫苯甲酰胺能够降低甜菜夜蛾种群的发育速率和繁殖力,这对甜菜夜蛾综合防治策略的制定有积极意义。

| Abstract: | In order to study the effects of chlorantraniliprole at sublethal concentrations on the development and activities of detoxification enzymes of Spodoptera exigua,the sublethal doses(LC25 and LC50)were estimated by the artificial diet incorporation bioassay method,and the sublethal effects were investigated,respectively.The results showed that the chlorantraniliprole at the LC25 and LC50 doses significantly prolonged the development duration of larvae and pupa of S.exigua,reduced the larval weight and pupal ... |
