摘　　要：目的比较BG-trap法与双层叠帐法对登革热媒介白纹伊蚊的监测效果,进一步探讨BG-trap法用于登革热媒介伊蚊监测的可能性,为制定更有效的登革热防控策略提供参考依据。方法实验选取江苏省3个设区市的6个户外监测点,于8—9月的3天时间中,分别于每日16:00-16:30、17:00-17:30、18:00-18:30三个时段同步开展BG-Trap法和双层叠帐法监测。结果BG-Trap法和双层叠帐法均能够有效地捕获白纹伊蚊的雌蚊,双层叠账法捕获的白纹伊蚊占比高于BG-Trap法(χ^(2)=16.034,P<0.01),两种方法捕获的白纹伊蚊雌蚊构成比之间差异无统计学意义(χ^(2)=0.162,P=0.687)。BG-Trap法捕获的白纹伊蚊平均密度指数为7.85±5.23只/(台·h),低于双层叠帐法的27.04±13.86只/(顶·h),差异有统计学意义(t=6.73,P<0.001)。结论BG-Trap法对登革热媒介白纹伊蚊监测效果不及双层叠帐法,其能否应用于登革热媒介伊蚊监测有待于进一步研究。Objective The effectiveness of the BG-Trap and human-baited double net trap(HDN)methods in monitoring Aedes albopictus were compared to assess the potential use of the BG-Trap method for dengue fever vector monitoring program.These findings would also provide a reference basis for formulating more effective dengue fever prevention and control strategies.Methods The study was conducted at six outdoor monitoring sites in three cities in Jiangsu Province in August and September,following a 3-d monitoring plan.Both traps were evaluated simultaneously at three time slots each day(16:00-16:30,17:00-17:30,and 18:00-18:30).Results Both the BG-Trap and HDN methods effectively captured female Ae.albopictus.The proportion of Ae.albopictus captured by the HDN method was higher than that captured by the BG-Trap method(χ^(2)=0.162,P=0.687),with no statistically significant differences in the composition ratio of male/female between the two methods(χ^(2)=0.162,P=0.687).The average density index of Ae.albopictus for the BG-Trap method was 7.85±5.23/h,significantly lower than that of the HDN method at 27.04±13.86/h under the same sampling sites(t=6.73,P<0.001).Conclusion These results suggest that the BG\|Trap method is less effective than the HDN method in Ae.albopictus monitoring.Further research is required to determine the applicability of this method for dengue fever vector monitoring.
