摘要
2007～2008年通过琼脂浸叶法测定山东不同地区烟粉虱和温室白粉虱对吡虫啉、高效氯氰菊酯和敌敌畏3种杀虫剂的敏感性。同一地区内,烟粉虱和温室白粉虱对3种杀虫剂敏感度基本相同。温室白粉虱和烟粉虱成虫对吡虫啉的敏感度高,LC50为60～95mg/L;其次是高效氯氰菊酯,LC50为124～153mg/L;最低为敌敌畏,LC50为1383～1965mg/L。但是青岛温室白粉虱种群对吡虫啉抗性程度已达中等水平,应加强其抗药性监测。
The susceptibility of adults of Bemisia tabaci and Trialeurodes vaporariorum to 3 insecticides,imidacloprid,beta cypermethrin and dimethyl-dichloro-vinyl-phosphate was studied with the method of leaf-dip bioassay.Results suggested that the susceptibility of B.tabaci and T.vaporariorum,collected from same areas in Shandong to 3 insecticides,had been approximately same.High variability in the susceptibility to dimethyl-dichloro-vinyl-phosphate,beta cypermethrin and imidacloprid was noted,ranging from low(LC50=1383-1965mg/L) to medium(LC50=124-153mg/L) to high lethal concentration 50(LC50=60-95mg/L).But T.vaporariorum(Qingdao) to imidacloprid had generated the medium level resistance.So we should streng their resistance monitoring.
