摘要: 目的 了解江苏省传疟媒介按蚊种群数量及其密度发展变化趋势。方法 于2015年7-9月在江苏省苏南、苏北和苏中部分县(市、区),采用半通宵人饵诱捕法和全通宵诱蚊灯捕蚊法进行传疟媒介按蚊调查,计算按蚊叮人率和灯诱密度。结果 2015年7-9月,11个监测点半通宵帐内人饵法共捕获按蚊1 942只,均为中华按蚊;7-9月各月上、下旬的中华按蚊叮人率分别为3.93、4.79、3.22、2.31、1.23和0.71只/(人·h);19:00-24:00中华按蚊叮人率分别为2.73、3.15、2.81、2.65和2.16只/(人·h)。全通宵室内外灯诱共捕获按蚊3 602只,均为中华按蚊;7-9月各月上、下旬的室内灯诱蚊密度分别为5.61、7.45、8.10、3.88、1.85和0.94只/(灯·夜),室外灯诱分别为16.30、18.10、25.03、15.94、5.76和4.09只/(灯·夜)。结论 江苏省传疟媒介为中华按蚊;中华按蚊活动高峰在7月下旬至8月上旬之间;在前半夜均能保持较高的活动频率,20:00-21:00为活动高峰期,在室外活动时间多于室内。应对居民加强防蚊意识教育,降低各种蚊媒传染病在人群中发生。

Abstract: Objective To analyze the trend of population and density of Anopheles mosquitoes, the malaria vectors, in Jiangsu province. Methods Anopheles mosquitoes were collected by half night human baiting and overnight light trapping from July to September in 2015 in south, north and part of middle Jiangsu counties and districts. The biting rates and the density of light trapping were analyzed. Results A total of 1 942 Anopheles mosquitoes were collected on 11 surveillance sites from July to September in 2015 by half night human baiting. All collected Anopheles mosquitoes were identified as An. sinensis. The biting rates of An. sinensis for the first ten days and last ten days each month during July to September were 3.93, 4.79, 3.22, 2.31, 1.23, and 0.71 mosquitoes/person·hour, among which the rates during 19:00 to 24:00 were 2.73, 3.15, 2.81, 2.65, and 2.16 mosquitoes/person·hour. Using overnight light trapping, 3 602 Anopheles mosquitoes were collected and identified as An. sinensis. The indoor density of An. sinensis for the first ten days and last ten days each month during July to September were 5.61, 7.45, 8.10, 3.88, 1.85, and 0.94 mosquitoes/night·light, while the outdoor density were 16.30, 18.10, 25.03, 15.94, 5.76, and 4.09 mosquitoes/night·light. Conclusion The malaria vector in Jiangsu province is An. sinenesis. The peak of activity for An. sinensis is from late July to early August. The activity frequency of An. sinensis is higher in the first half night, especially during 20:00-21:00. Anopheles sinensis stays outdoor longer than indoor. To reduce the mosquito-borne diseases among residents, the health education on mosquito prevention is needed to be strengthened.
