摘要:

目的 了解河南省永城市准备越冬蚊虫种类、数量及其在居民区分布的高度梯度,为制定适宜防制措施提供科学依据。方法 永城市市区近郊和市内分别选择2个小区,用目测法进行现场蚊虫数量估计,同时对其中数个单元楼道内的蚊虫用人工小时法进行蚊虫数量的校准。结果 2010年11月在永城市4个居民小区均发现有蚊虫停落栖息,捕获蚊种全部为淡色库蚊,分布在不同楼层间,1层蚊虫数量最多,在高度分布上从1层向高层呈现依次递减,6层以上数量很少;目测法与人工小时法获得类似的结论;不同小区的蚊虫密度差异与小区的外围环境以及小区的具体防蚊措施具有密切关系。结论 居民区的蚊虫来源于外围环境,居民区采取适当的隔离措施对降低蚊虫密度具有良好作用;化学防蚊措施的实施应该以居民区楼层的1层为主。

Abstract:

Objective To identify the species, number and landing height of wintering mosquitoes in Yongcheng city, Henan province, China, so as to provide evidence for the development of vector control strategies. Methods Two residential blocks in urban and suburb areas were selected as surveillance sites. The number of mosquitoes was determined through visual observation, which was then adjusted with data from indoor settings using the labor hour method. Results All landing mosquitoes from the surveillance sites mentioned above were Culex pipiens pallens. The mosquito number differed across floors. Most of mosquitoes were on the first floor, and the number declined with the increasing of height. Conclusion Mosquitoes in residential areas of Yongcheng might come from the external environment. Physical isolation might have a good effect in avoiding mosquito bites. Chemical method should be used as the primary option for mosquito control on the first floor.

Key words: Culex pipiens pallens, Overwintering, Landing height gradient
