Abstract:
Taking Cosmopolites sordidus as test insect，the indoor toxicity and efficacy of six insecticides to the adults of C.sordidus were tested by corm-dipping method and topical application method respectively.The results showed that the toxicity of six insecticides to C.sordidus adults from the highest to the lowest could be arranged by：lambda-cyhalothrin>isoprocarb>trichlorphon>imidacloprid>acetamiprid>abamectin，and the LC50 values of 24 h were 22.847 2，45.460 1，110.695 7，158.669 7，192.486 1，218.659 3 mg/L，respectively.The indoor efficacy trials showed that the corrected mortality of all the tested insecticides but trichlorphon on C.sordidus adults reached 100% in the 14 days after treatment.Moreover，lambda-cyhalothrin and isoprocarb had better instant effect，and imidacloprid，acetamiprid and abamectin had longer persistence.Lambda-cyhalothrin，isoprocarb，imidacloprid，acetamiprid and abamectin could be used as potential insecticides to control C.sordidus in field.
