Abstract：Objective To learn the resistance of Aedes albopictus to commonly used insecticides in Shijiazhuang City,and to provide a scientific evidence for mosquito control.Methods The immersion method was adopted for larval resistance test,while the contact tube method was for adult resistance test.Results The LC50 of permethrin、deltamethrin,fenitrothion,temephos and pyriproxyfen were respertively 0.01636,0.00339,0.03338,0.00504 and 4.85×10-5 mg/L to the larvae of Aedes albopictus,showing that the larvae were low resistant to permethrin,deltamethrin,temephos and pyriproxyfen,sensitive to fenitrothion.The Aedes albopictus adults were resistant to deltamethrin and beta-cypermethrin,possible resistant to alpha-cypermethrin and lambda-cyhalothrin,but sensitive to bendiocarb.Conclusion Aedes albopictus in Shijiazhuang City developed some resistance to pyrethroid insecticides.Insecticides should be applied scientifically to slow down the insecticide resistance development in mosquitoes.
