| 摘 要： | 结果表明:溴氰菊酯对二化螟(Chilo suppressalisW alker)4龄幼虫和稻纵卷叶螟5龄幼虫田间种群的LD50分别为0.0089、0.0579μg.头-1;氰戊菊酯对这2种水稻害虫的LD50分别为0.0766和0.1688μg.头-1,其触杀毒力低于溴氰菊酯;0.375、0.450 L.hm-22种剂量的25 g.L-1溴氰菊酯乳油对二化螟的田间防治效果分别为74.88%、81.18%,显著高于200 g.L-1氰戊菊酯乳油;溴氰菊酯和氰戊菊酯乳油对稻纵卷叶螟的防效相当,均可较好地控制其为害.

| Abstract: | The results were as follows: the LD_(50) of deltamethrin to Chilo suppressalis and C.medinalis were 0.0089 and 0.0579 μg per pest,but the LD_(50) of fenvalerate to these two kinds of pests were 0.0766 and 0.1688 μg per pest, respectively,it was lower than that of deltamethrin;the efficacies of 25 g·L~(-1)deltamethrin EC at the dose of 0.375 and 0.450 L·hm~(-2) were 74.88% and(81.18%),respecctively.It suggested that deltamethrin could control C.suppressalis more effectively than fenvalerate,and there was no significant difference of control efficacy to C.medinalis between deltamethrin and fenvalerate,they could control C.medinalis effectively. |
