7种杀虫剂对江西地区草地贪夜蛾室内毒力测定
Laboratory Toxicity of Seven Insecticides Against Spodoptera frugiperda Larva in Jiangxi Province
摘要
Abstract
[Objective]Spodoptera frugiperda(J.E.Smith)is a highly damaging omnivorous pest for which chemical pesticides are the last line of integrated pest management.It is important to identify the toxicity of different insecticides against S.frugiperda for the control of this pest.[Method]In this study,the toxicity of seven chemical insecticides against S.frugiperda populations in Nanchang,Jiangxi was investigated by laboratory toxicity measurements.[Result]The toxicity was from strongest to weakest in the following order:emamectin benzoate>chlorfenapyr>chlorantraniliprole>lufenuron>phoxim>indoxacarb>lambda-cyhalothrin,and their values of lethal concentration of 50%were 0.023 1,1.164 2,2.031 5,2.035 5,2.359 3,15.957 5 and 25.688 6 mg/L,respectively.[Conclusion]Therefore,emamectin benzoate,chlorfenapyr and chlorantraniliprole are recommended as chemicals for emergent prevention and control of S.frugiperda in Jiangxi.This study also provides a theoretical basis for chemical control and regional management of insecticide-resistance in Jiangxi.关键词
