目的:开展台风水灾之后农村蚊蝇等虫媒密度监测及防制效果评价,为提高救灾防病水平提供依据。方法:在遭受水灾的村庄采取环境治理、化学杀灭等干预措施前和干预措施后,分别设立农贸市场、五小行业、公厕、垃圾站等场所为监测点,开展蚊蝇密度测定,蝇类密度监测:室内采用粘捕法,室外采用笼诱法。蚊密度监测:采用诱蚊灯法监测成蚊密度,采样容器指数法,记录村民庭院内容器数量、积水容器数量、容器蚊幼虫阳性数量。结果:干预后监测捕蝇数分别为98只和481只,种类均为家蝇;阳性率分别降低为55.56%和65.08%,与治理前阳性率比较,差异有统计学意义(χ2=7.62,P<0.05;χ2=8.45,P<0.05);2个村庄调查50户家庭庭院结果显示,蚊幼阳性率为15%,与治理前阳性率比较,差异有统计学意义(χ2=9.48,P<0.05)。结论:水灾过后应积极采取以清理蚊蝇孳生地为主的综合防制措施,降低蚊蝇密度,同时评价病媒生物防制效果和虫媒疾病发生风险,对救灾防病有积极意义。 OBJECTIVE: To monitor the density of insects and mosquitoes in rural areas after typhoon floods and evaluate their control effects, so as to provide basis for improving the level of disaster prevention and disease prevention. Methods: In the villages affected by floods, environmental monitoring, chemical killing and other interventions were taken before and after the interventions. Farmers’ markets, five small trades, public toilets and garbage dumps were set up as monitoring points respectively. Density of mosquitoes and flies Density monitoring: indoor sticky catch method, the outdoor cage method. Mosquito density monitoring: mosquito lamp method to monitor the density of adult mosquitoes, sample container index method, record the number of containers in the village courtyard, the number of water containers, container mosquito larvae positive number. Results: After the intervention, the number of traps caught was 98 and 481, respectively, and the species was housefly. The positive rates were reduced to 55.56% and 65.08%, respectively, which were significantly different from those before treatment (χ2 = 7.62, P <0.05; χ2 = 8.45, P <0.05). The survey results of 50 families in two villages showed that the positive rate of mosquito was 15%, which was significantly different from the positive rate before treatment (χ2 = 9.48, P <0.05). Conclusion: After the floods, we should take active measures to reduce mosquitoes and flies breeding density, reduce the density of mosquitoes and flies, evaluate the effectiveness of vector control and the risk of insect-borne diseases, which is of positive significance to disaster prevention and disease prevention.
