Abstract: Objective To study the efficacy of emulsifiable concentrate against Culex pipiens pallens,Musca domestica vicina and Blattella germanica in lab.Methods The laboratory efficacy test,the analogous site efficacy test and the forcing-contact method efficacy test had been done against Culex pipiens pallens,Musca domestica vicina and Blattella germanica.Results Laboratory efficacy test showed that KT_(50) of the insecticide was(2.40 min) and(24 h) mortality was 100% against Culex pipiens pallens;KT_(50) of the insecticide was(2.81 min) and(24 h) mortality was 100% against Musca domestica vicina;KT_(50) of the insecticide was(4.67 min) and(72 h) mortality was 100% against Blattella germanica.Mimic field efficacy test showed that(1 h) knock down rate was 100% and(24 h) mortality was 100% against Culex pipiens pallens;(1 h) knock down rate was(98.03%) and(24 h) mortality was 100% against Musca domestica vicina;(1 h) knock down rate was 95% and(72 h) mortality was 100% against Blattella germanica.On the glass surface of the three,the efficacy was the best,the long-lasting efficacy was over 90 days for the three insects.Conclusion 10% emulsifiable concentrate had good efficacy against Culex pipiens pallens,Musca domestica vicina and Blattella germanica.
