摘　　要：目的评价BG-Sentinel mosquito trap（BGS-trap）与网格化管理联合应用在登革热疫情防控中的可行性和有效性。方法 2015年中山市G镇A、G社区在研究开始前进行1次杀灭成蚊活动,有登革热疫情的A社区应用BGS-trap进行伊蚊成蚊监测和网格化管理,无疫情的G社区进行常规消杀处理和BGS-trap监测,比较两种模式对伊蚊成蚊密度的控制结果。结果 A社区累计监测20 d,放置BGS-trap 23个,捕获伊蚊278只,G社区累计监测13 d,放置BGS-trap 8～9个,捕获伊蚊531只,G社区伊蚊成蚊密度高于A社区,且差异有统计学意义（Z=2.667,P=0.000）。结论在登革热疫情中,BGS-trap与网格化管理联合应用能客观、及时地评估并指导灭蚊工作,从而降低疫情扩散的风险,值得推广应用。ObjectiveTo evaluate the feasibility and effectiveness of the combined application of BG- Sentinel mosquitotrap（BGS-trap） and grid management for dengue vector surveillance in dengue fever outbreak.MethodsIn 2015, in earlystage of the study, two different adult mosquito elimination operations were launched in community A and community G ofG town in Zhongshan city, community A received the combination of BGS- trap for dengue vector surveillance and gridmanagement, while community G used the routine disinfection treatment and surveillance of BGS-trap, the results of thesetwo models were compared at the end of the study.ResultsCommunity A was continuously monitored for 20 d, duringwhich 278 Aedes mosquitoes were caught from 23 BGS-traps. The community G was continuously monitored for 13 d, 531 Aedes mosquitoes were collected from 8-9 BGS-traps. The results of wilcoxon rank-sum test showed that Aedes mosquitodensity of community G was higher than that of community A（Z=2.667, P=0.000）.ConclusionThe combinedapplication of BGS- trap and grid management offered objective and timely assessment, which effectively supported theguidance of mosquito control and reduced the risk of dengue＇s spread. It is worthy of further promotion and application.
