Abstract：Objective To evaluate the lethal efficacy of commonly used mosquito larvicides against larvae and pupae of Aedes albopictus in Guangzhou,so as to provide reference for reasonably using of insecticides in vector control of mosquito-borne diseases such as dengue fever.Methods According to national standards(GB/T 31711-2015),container experiment method was adopted to determine the lethal efficacy of 4 kinds of larvicides against larvae and pupae of Ae.albopictus in laboratory.Results All four kinds of larvicides had good killing effects on the larvae,but their effects on pupae vary greatly.The 96-h mortalities of larvae were 95.00％～100.00％.Fenthion and beta-cyfluthrin had good killing effects on pupae,the 72-h mortalities were 88.33％～100.00％.Imidacloprid had poor effect,the 72-h mortality was 16.67％.Bacillus thuringiensis have been ineffective on pupae.Conclusion When dealing with difficult cleared mosquito breeding water bodies,larvicides should be released according to the life history stages of mosquito breeding in it.
