摘要: 目的 调查江苏省徐州市重要媒介蚊虫白纹伊蚊的分布及种群密度,评估登革热在徐州市暴发流行的风险。方法 于2018年1-12月,采用诱蚊诱卵器法对白纹伊蚊进行持续监测,采用χ2检验分析不同月份、不同生境和不同地区的白纹伊蚊诱蚊诱卵指数(MOI)之间的差异,观察徐州市白纹伊蚊的季节消长趋势及各生境和地区的白纹伊蚊分布差异。结果 据2018年监测数据显示,不同月份、不同生境和不同地区的白纹伊蚊分布不同。白纹伊蚊自5月开始出现,随后蚊虫密度逐渐增高,8月达到高峰(MOI为64.24),其后逐渐降低。在蚊虫盛行的季节,居民区的白纹伊蚊MOI最高为36.33,公园(MOI为28.19)和学校(MOI为24.62)白纹伊蚊MOI差异无统计学意义(χ2=1.722,P=0.107);居民区和非居民区白纹伊蚊MOI在6月(χ2=4.591,P=0.038)、9月(χ2=18.100,P=0.001)、10月(χ2=3.734,P=0.035)差异有统计学意义。另外,对比分析2018年徐州市云龙、铜山、开发和鼓楼区白纹伊蚊MOI,其中云龙区和开发区(χ2=21.010,P<0.01)、开发区和鼓楼区(χ2=19.700,P<0.01)、开发区和铜山区(χ2=12.500,P<0.01)的白纹伊蚊MOI差异有统计学意义,且开发区白纹伊蚊的MOI最高,达41.08。结论 徐州地区应提高对伊蚊的监测力度,监测重心应偏向居民区。采用敏感、科学、客观的监测方法,及时发现伊蚊密度升高并进行防控,可有效降低蚊媒传染病在徐州市暴发流行的风险。

Abstract: Objective To investigate the distribution and population density of Aedes albopictus in Xuzhou, Jiangsu province, China, and to evaluate the risk of outbreak of dengue fever in Xuzhou. Methods From January to December 2018, Ae. albopictus mosquitos were continuously surveyed by mosquito ovitraps. The differences in mosquito ovitrap index (MOI) between Ae. albopictus in different months, habitats, and regions were analyzed by the χ2 test to observe their seasonal fluctuation in Xuzhou and the variation of their distribution in different habitats and regions. Results According to the surveillance data in 2018, the distribution of Ae. albopictus varied between different months, habitats, and regions. Aedes albopictus began to appear in May, and their density mounted to the peak in August (MOI=64.24), followed by a gradual decline. During mosquito seasons, their density was the highest in the residential areas (MOI=36.33) and showed no significant difference between parks and schools (MOI:28.19 vs 24.62, χ2=1.722, P=0.107). Aedes albopictus MOI showed significant differences between residential and non-residential areas in June (χ2=4.591, P=0.038), September (χ2=18.100, P=0.001) and October (χ2=3.734, P=0.035). Comparison of MOI of Ae. albopictus in Yunlong, Tongshan, Kaifa, and Gulou districts of Xuzhou in 2018 found significant differences between Yunlong and Kaifa districts (χ2=21.010, P<0.01), Kaifa and Gulou districts (χ2=19.700, P<0.01), and Kaifa and Tongshan districts (χ2=12.500, P<0.01). The MOI in Kaifa district (MOI=41.08) was the highest. Conclusion The monitoring of Ae. albopictus should be strengthened in Xuzhou, particularly in residential areas. Sensitive, scientific, and objective surveillance methods should be adopted for timely detection, and prevention and control of increase in Ae. albopictus density can effectively reduce the risk of the mosquito-borne disease outbreak in Xuzhou.
