Abstract: Objective To investigate the current status of vectors infestation in the urban area of Wuhan, China, in 2017, and to provide a scientific basis for vector control and National Hygienic City construction. Methods From June to September, 2017, a field investigation was performed to evaluate the current status of the vectors infestation in different types of units (places). The rodent trace method was used for the survey of rodents; the path method and the larva dip method were used for the survey of mosquitoes; visual observation was used for the survey of flies and cockroaches, and of the investigation of facilities for the prevention of rodents and flies. Results The total positive rate of indoor rodent density was 10.1%, the total failure rate of rodent-poof facilities was 17.2%, and the total path index of outdoor rodent density was 3.4. The total path index of water in small containers was 4.3, and the total dip index of large and medium waters was 5.8%. The density of mosquito larvae per positive dip was 5.5. The total positive rate of indoor adult flies was 7.3%; the total failure rate of fly-poof facilities was 14.0%; the total positive rate of fly breeding sites was 3.0%. The total invasion rate of indoor adult nymphae was 4.1%; the total positive rate of oothecae was 1.2%; the total positive rate of cockroach trace was 4.6%. Conclusion The current status of the vectors infestation in different types of units (places) of Wuhan obtained in this investigation provides background data for effective vector control and the consolidation of National Hygienic City in the future.

摘要: 目的 调查2017年武汉市城区范围内重要病媒生物侵害情况,为今后病媒生物防制和创建国家卫生城市工作提供科学依据。方法 于2017年6-9月对武汉市建成区范围内29种不同类型单位(场所)的重要病媒生物侵害情况进行现场调查。鼠类调查采用鼠迹法,蚊类采用路径法和幼虫勺捕法,蝇类、蜚蠊采用目测法,防鼠设施和防蝇设施均采用目测法。结果 室内鼠密度的总体阳性率为10.1%;防鼠设施总体不合格率为17.2%,外环境鼠密度总体路径指数为3.4。小型容器积水总体路径指数为4.3,大中型水体总体采样勺指数为5.8%,每阳性勺蚊幼虫密度为5.5只/勺。室内成蝇总体阳性率为7.3%,防蝇设施总体不合格率为14.0%,蝇类孳生地总体阳性率为3.0%。室内蜚蠊成若虫总体侵害率为4.1%,卵鞘总体查获率为1.2%,蜚蠊迹总体阳性率为4.6%。结论 初步掌握了武汉市各类型单位(场所)重要病媒生物侵害情况,为今后有效开展病媒生物防制和巩固国家卫生城市工作提供了本底资料。
