摘　　要：目的了解输入性蚊类与入境船舶上栖息场所微小气候因素的相关关系。方法在秦皇岛港检疫锚地对入境国际航行船舶存在输入性蚊类的场所进行调查登记,对微小气候因素包括温度、湿度、风速等进行测定并对监测结果进行分析。结果2005年4-10月共调查168艘次入境国际航行船舶,输入性蚊类阳性率为64.28%(108/168)。输入性蚊类自5月初气温高于15℃时开始出现,至10月中旬气温低于15℃时基本消失。其密度与栖息场所的温度、湿度呈正相关关系,风速大于3m/s时蚊虫基本不再飞翔。结论输入性蚊类在入境船舶上与栖息场所的微小气候因素特别是温、湿度有着极为密切的关系。Objective To find out the distribution and the correlation of introduced mosquitoes and micrcclimate factors on entry international ships, and provide technical supports for the surveillance and control of the introduced mosquitoes at seaports. Methods The places where the mosquitoes dwelled in the ships were investigated, and the microclimate factors including temperatures, relative humidity and wind speeds were measured at quarantine anchorage of Qinhuangdao port, and the data was analyzed. Results 168 entry ships were checked from April to October 2005. The positive rate of entry ships carried the introduced mosquitoes was 64.28 % （108/168）. The introduced mosquitoes appeared when the temperature exceeded 15 ℃ at the early of May, and it basically disappeared when the temperature was under 15℃ at the mid-ten days of October. There was the positive correlation between the densities of introduced mosquitoes and the temperature and the relative humidity. Mosquito could not fly when the wind speed was higher than 3 m/s. Conclusion It showed that the introduced mosquitoes population on entry ships was close relationship with the microclimate factors especially temperature and humidity. So it was advised the surveillance and control of the introduced mosquitoes carried by entry ships from abroad should be carried out properly.
