Abstract: Objective To study efficacy of the mixture including pyrethroid, avermectin and tebuconazol to hygiene pest. Methods Efficacy of this mixture was evaluated with KT₅₀ and LC₅₀ of them to hygiene pest. Results This mixture had better efficacy than other mixtures composed of part elements to mosquito, housefly and cockroach(P<0.001). The rate of knockdown and the mortality of the mixture to Mulex pipiens pallens, Musca domestica or Blattella germanica were all 100% after treated for 1 h and 24 h, respectively. The LC₅₀ value of it to the larvae of C.pipiens pallens and M.domestica were 0.025 μg/ml and 0.41 μg/ml, respectively. The oothecae hatchability of B.germanica and Periplaneta americana decreased to 94% and 76%, respectively. The knockdown rate of the mixture to C.pipiens pallens, M.domestica, B.germanica and P.americana were all 100% after 1 h treated in analogous site. The 24 h mortality to C.pipiens pallens, M.domestica orB.germanica was 100% and the 48 h mortality to P.americana also reached 100%. According to GB/T 17322.1, the control efficacy of the mixture achieved A degree. Conclusion This mixture had good control effect on common hygiene pest, and also provided new method for the control of agriculture pest and hygiene pest.
