目的 调查浙江省义乌市2017年不同月份白纹伊蚊密度,并分析其影响因素,为义乌市蚊媒传染病防控提供科学依据。方法 2017年4-11月在义乌市按不同地理方位选择4个街道的村或社区作为监测点,每月中旬监测1次,每次监测100户,计算布雷图指数(BI)、容器指数(CI)和房屋指数(HI),分析不同生境、不同容器对白纹伊蚊密度的影响。采用SPSS 24.0软件对不同容器白纹伊蚊孳生情况进行χ2检验。结果 义乌市2017年4-11月平均BI为13.75,7和10月BI较高,分别为18.00和23.00,除4月外其他月份BI均>5。白纹伊蚊的阳性容器主要有贮水池、缸、盆类、闲置容器类积水、轮胎以及盆景与水生植物类等,其中盆景与水生植物的CI最高,达20.00%,但不同类型积水容器阳性率差异无统计学意义(χ2=6.373,P=0.383);所有生境的平均BI均>5,其中住宅周边商用房和高档类别墅住宅的BI较高,分别为44.00和26.37。结论 2017年义乌市白纹伊蚊密度较高,需要采取综合措施清理白纹伊蚊孳生地,降低蚊媒传染病本地暴发风险。
Objective To investigate the population density of Aedes albopictus in different months in Yiwu, Zhejiang province, China, and analyze its influencing factors, and to provide a scientific basis for the prevention and control of mosquito-borne diseases in Yiwu. Methods The villages or communities in four streets in Yiwu were selected in different geographical locations as surveillance sites. Mosquito surveillance was carried out once a month in the middle of the month from April to November in 2017, with 100 households being surveyed each time. Breteau index (BI), container index (CI) and house index (HI), were calculated to analyze the population densities of Ae. albopictus in different habitats and containers. SPSS 24.0 software was used to conduct chi-square test to analyze the breeding status in different containers. Results Mean BI was 13.75 in Yiwu from April to November, 2017. The BI in July and October was high (18.00 and 23.00, respectively), and the BI in all months was greater than 5 except for that in April. The containers with Ae. albopictus were mainly cisterns, tanks, basins, and unused containers with water, tires, miniascape, and aquatic plants, among which, the CI of miniascape and aquatic plants was highest and up to 20.00%. However, there was no significant difference in the positive rate between different types of containers with water (χ2=6.373, P=0.383). The mean BI in all habitats was greater than 5, of which, the commercial houses around residential buildings and high-end villas had the highest BI (44.00 and 26.37, respectively). Conclusion The population density of Ae. albopictus was high in Yiwu in 2017. Comprehensive measures should be adopted to clean up the breeding sites of Ae. albopictus to reduce the risk of local outbreaks of mosquito-borne diseases.
