Abstract: Objective To investigate the species composition and population density of mosquitoes before impoundment and after recession in the fluctuating zones of the Three Gorges Reservoir region and to provide a basis for surveillance of mosquito vector and mosquito-borne diseases. Methods Four surveillance sites were established in the typical fluctuating zones at upper, middle, and lower streams of the Three Gorges Reservoir region. For each surveillance site, 3 lamp trapping cages were placed at each of the three different altitudes (10 m altitude difference). The surveillance was carried out before impoundment and after recession in 2010. Results In 2010, a total of 101 mosquitoes were captured with 90 lamp-times, which belonged to 4 species: Culex tritaeniorhynchus, which accounted for 21.78% (n=22); Anopheles sinensis, which accounted for 16.83% (n=17); Cx. pipiens, which accounted for 16.83% (n=17); Armigeres subalbatus, which accounted for 6.93% (n=7); other species, which accounted for 37.63% (n=38). Conclusion The fluctuating zones of the Three Gorges Reservoir region provide breeding sites for mosquitoes. Mosquito density is low in these areas, and shows a decreasing trend with increasing altitude. Vector of Japanese encephalitis, Cx. tritaeniorhynchus, and malaria vector, An. sinensis, exist in these areas.

摘要: 目的 了解2010年长江三峡水库消落区内退水后、蓄水前的蚊虫种类构成和密度情况,为蚊媒后续监测及蚊媒病的防制提供基础依据。方法 在三峡库区上、中、下游选择4个典型消落区作为监测点,于2010年分别在库区退水后和蓄水前进行蚊媒监测。每个监测点按10 m海拔高程差设置3个梯度,每个梯度每次设3盏诱蚊灯。结果 2010年消落区成蚊监测共布放90灯次,捕获蚊虫101只,其中三带喙库蚊22只,占捕获总数的21.78%;中华按蚊和致倦库蚊各占16.83%;骚扰阿蚊占6.93%,其他蚊种占37.63%。结论 三峡水库消落区提供了蚊类孳生环境,蚊密度处于低水平,表现了低海拔向高海拔的递减趋势;消落区存在流行性乙型脑炎传播媒介三带喙库蚊和疟疾传播媒介中华按蚊。
