Contact toxicity and efficacy of pyrethroid insecticides to rice pests

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;氰戊菊酯对这2种水稻害虫的LD50分别为0.0766和0.1688μg/头,其触杀毒力低于溴氰菊酯;0.375、0.450 L/hm,2种剂量的25 g/L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....
