Abstract:Objective To explore the method of indoor residual spraying in military tents for mosquito control.Methods The military tents were set up in the wild,and their inner walls were residual sprayed with wetable powder (10% beta cypermethrin and 2% meperfluthrin) or wettable powder plus extension agent.The effective dose was 30 mg/m2.After a period of treatment,female mosquitoes were introduced in the tents.The knockdown rate and mortality of mosquitoes were measured.Results The insecticide dilution did not distribute evenly,and the knockdown rate and mortality of mosquitoes were all around 30% one day after treatment,when wettable powder without plus of adhesion extension agent was used for the residual spraying in the inner wall of the tent.When the wettable powder plus with adhesion extension agent was used,both of the knockdown rate and mortality of mosquitoes were over 90%.And the mortality of mosquitoes remained above 80% one month after the application.However,both of the knockdown rate and mortality of mosquitoes declined to less than 30% two months after the application.Conclusion In the residual spraying of pyrethroids in military tents,the adhesion extension agent should be used to improve the distribution and adhesion of insecticides,and the maximum treatment interval might not be longer than one month to maintain good effect for mosquito control.
