摘　　要：目的了解江苏省不同地区中华按蚊季节消长与夜间活动规律,为消除疟疾提供科学依据。方法2011年,选择江苏省13个直辖市各1个乡(镇)作为疟疾媒介监测点,采用通宵室外帐内人饵诱捕法,观察各监测点中华按蚊的季节消长和夜间活动规律。并按照监测点的地理位置,划分为苏南、苏中、苏北并对数据进行统计分析。结果 2011年,江苏省13个疟疾媒介监测点共捕获2044只按蚊,经鉴定全部为中华按蚊,未发现嗜人按蚊。江苏省中华按蚊季节消长密度高峰为7月下半月,对苏北地区、苏中地区和苏南地区的中华按蚊数量进行统计学分析,差异无统计学意义(F=1.769,P=0.19)。江苏省中华按蚊夜间活动高峰出现在19:00至22:00间的3h,共捕获中华按蚊1388只,占全部12个时间段所捕获中华按蚊数的的67.91%;中华按蚊在清晨时分又出现一个小高峰,5:00至6:00时间段共捕获中华按蚊184只,占全部12个时间段的9.00%。对苏北地区、苏中地区和苏南地区的中华按蚊数量进行统计学分析,差异有统计学意义(F=291.88,P=0.000)。结论应做好傍晚和清晨的个人防护措施,避免蚊虫叮咬,降低疟疾的传播机会。仍应继续加强媒介的监测与控制,为消除疟疾起到以点带面的作用。Objective To make a clear understanding of seasonal fluctuation and nocturnal activity patterns of Anopheles sinensis in different areas of Jiangsu province.Methods In 2011,13 townships were selected from each of the 13 cities in Jiangsu province as malaria vector monitoring sites,and indoor overnight capture of malaria vectors with human bait in the bed nets was used to survey the seasonal fluctuation and nocturnal activity patterns of Anopheles sinensis in each monitoring site.Results Totally 2 044 mosquitoes were captured from 13 monitoring sites,all the mosquitoes identified were Anopheles sinensis and no Anopheles anthropophagus was detected.The density peak of seasonal fluctuation of Anopheles sinensis was at second half of July,and there were no significant differences in number in the southern,middle and northern parts of this province（F=1.769,P=0.19）.The nocturnal activity peak of Anopheles sinensis was 3 hours from 19：00 to 22：00,and 67.91% of the 1 388 Anopheles sinensis were captured in the 12 time intervals.Another small peak appeared from 5：00 to 6：00 and 184 Anopheles sinensis were captured,accounted for 9.00% of the mosquitoes captured in 12 time intervals,showing significant differences in number in three parts of the province（F=291.88,P=0.000）.Conclusions Individual protection and monitoring be strengthened to avoid mosquito bite and reduce the transmission of malaria.
