| 摘 要： | 研究了氟虫腈对不同虫态二化螟Chilo suppressalis的作用特点、持续毒性及对解毒酶的诱导效应。结果表明:氟虫腈对二化螟幼虫具有很强的毒杀作用,且毒杀作用随幼虫龄期的增长而逐渐减弱;对二化螟蛹的羽化具有较低的抑制作用;对卵孵化无抑制作用。亚致死剂量氟虫腈能引起幼虫持续死亡,降低存活试虫体重增长率和蛹重。用亚致死剂量氟虫腈处理4龄幼虫后,对其体内羧酸酯酶活性具有明显的诱导效应和时间效应,对谷胱甘肽S--转移酶活性的诱导效应仅在药剂处理后3h内较为显著,对多功能氧化酶活性表现出较强的诱导效应,比活力约为对照的1.37倍。

| Abstract: | The characteristics of action,persistent toxicity and enzyme induction of fipronil on rice stem borer,Chilo suppressalis were taken into investigation.Results showed that fipronil had powerful insecticidal activity against the larvae of Chilo suppressalis,but the sensitivity of the larvae to the toxicity of fipronil was gradually decreased along with their growth.However,fipronil showed lower inhibitory activity against pupae eclosion and no activity against egg hatchability.Fipronil with sublethal doses could persistently induce the larvae dead,and decrease the rate of weight increasing of survival larvae, even the weight of succedent pupae.After treated by fipronil with sublethal doses,the activity of carboxylesterase in 4th instar larvae was induced and kept higher than the control except for the larvae metamorphosis;glutathione-S-transferases activity was significantly improved in 3 hours from the drug application;and the activity of microsomal multifunctional oxidases was enhanced up to 1.37 times higher than the control during the whole experiments. |
