Objective To investigate the susceptibility of Armigeres subalbatus to commonly used pesticides in Suqian city, Jiangsu province. Methods Dipping method was used to detect LC50 of Suqian field population of Ar. subalbatus to abate, fenobucarb, deltamethrin, betacypermethrin and permethrin. Results The LC50(mg/L)of Suqian population of Ar. subalbatus to abate, fenobucarb, deltamethrin, betacypermethrin and permethrin was 0.059 36, 2.563 5, 0.000 457 2, 0.000 443 2 and 0.001 701 respectively, was 7.24, 2.68, 0.21, 0.09, and 0.11 times of LC50 of Suqian population of Cluex pipiens pallens collected from same site on same pesticides. Conclusion Compared with Suqian population of Cx. pipiens pallens, Ar. subalbatus was more resistant to organophosphorus and carbamate pesticides, more susceptible to pyrethroids. IPM was recommended in the control of Ar. subalbatus. Controlling larvae by eliminating of dirty water of vessels and ditches, using pyrethroids or B.t.i. or B. sphaericus biopesticide, were better than controlling adults of Ar. subalbatus, but chemical control on adults of Ar. subalbatus would be the first selection at high vector density or during epidemic period of vector diseases.
