目的 掌握海南省城区蚊虫种群分布、密度及季节消长规律,为蚊媒相关治理提供科学依据。方法 于2012年1－12月采用夜间灯诱法在海南省18个市(县)城区开展逐月监测。结果 海南省城区蚊虫种类较为丰富,共捕获40 448只,隶属4属10种,以致倦库蚊(46.88%)为优势蚊种,全年监测成蚊密度为1.17～4.86只/(h栏目:灯),平均密度为2.82只/(h栏目:灯),蚊虫的季节消长曲线呈单峰型,高峰出现在4－5月。结论 初步掌握了海南省城区蚊虫种群分布、密度、季节消长等情况,为进一步开展系统监测、蚊虫防治和蚊媒疾病预防提供了科学参考。

Objective To determine the species and density of mosquitoes and their seasonality in the urban areas of Hainan province, China and to provide a technical foundation for controlling mosquito vectors. Methods From January to December 2012, mosquitoes were captured by light-traps at night in the urban areas of 18 cities or counties of Hainan province to determine the species composition and their density. Results A total of 40 448 mosquitoes (10 species, 4 genera) were collected in the urban areas of Hainan; Culex quinquefasciatus Say was the dominant species, accounting for 46.88% of all mosquitoes. The density index of mosquitoes was 1.17-4.86 mosquitoes per light trap per hour, and the mean value was 2.82 mosquitoes per light trap per hour. The seasonalityof mosquitoes was unimodal, and the peakoccurred from April to May. Conclusion The species and density of mosquitoes and their seasonalityin the urban areas of Hainan province were well documented in this stusy, which provides a technical foundation for further systematic monitoring of mosquitoes, control operations, and prevention of mosquito?borne diseases.
