Objective By applying BG-Trap to Aedes mosquito monitoring sites,the feasibility of applying this method to routine and emergency surveillance of dengue mosquito vectors was discussed.Methods The Aedes mosquito monitoring site was monitored in phases.The monitoring results were analyzed by Chi-Square process and t test of non-parametric statistical analysis.Results The monitoring effect during 15:00-7:00 was significantly higher than that of during 9:00-11:00(♀:χ2=18.963,df=1,P＜0.001;♂:χ2=18.667,df=1,P＜0.001;total:χ2=37.500,df=1,P＜0.001);Starting from 12 o'clock,the mosquito attractor effect was calculated every hour,and the best attractor effect was 15:00-19:00.The average mosquito catch per hour from 15:00 to 19:00 was 61.8±2.1 mosquitoes per hour.The average hourly mosquito attractors during 15:00-19:00 was siginificantly higher than that of 12:00-15:00(♀:t=27.5,df=146,P＜0.001;♂:t=67.8,df=156,P＜0.001;Total:t=101.6,df=304,P＜0.001).Conclusion BG-trap method can be introduced into the routine and emergency surveillance of dengue vector Aedes.
