Abstract：Objective To experiment and evaluate the effect of an air curtain machine in preventing mosquitoes and flies from invading the room by setting up a simulated field test.Methods According to the application principle of the air curtain machine and the method of Laboratory efficacy test methods and criterions of public health insecticides for pesticide registration-Analogous site(GB/T 13917.10-2009),the air curtain machine was installed in the center of a closed corridor of a certain teaching building to set up a simulated test air curtain door,and the effective way of attracting mosquitoes and flies was used,the efficiency of air curtain door on mosquito and fly was observed and statistically analyzed.Results When the air curtain machine was not turned on,the attractive conditions for mosquitoes and flies were significant,t=7.47,t=7.28,P＜0.01.When the air curtain machine was turned on,the wind speed on the ground could reach 6.40 m/s,the blocking rate to mosquitoes was 100%with and without attractant,and the blocking rate to houseflies was 96.14%and 97.26%with and without attractant,respectively.Conclusion The air curtain machine is used for the entrance of food processing places,dining places and other public health places,and can effectively block the invasion of mosquitoes and flies.
