Abstract: Objective To investigate the malaria vector species in the historical distribution areas of Anopheles lesteri in Fujian province, China, and to provide a basis for developing the measures of the prevention and control of malaria vectors for consolidating local malaria elimination. Methods The malaria vector species were investigated by the trapping method and the full search method during the season of mosquito activities (from May to October) in 2011-2017 in Nanping and Sanming, which were the historical distribution areas of An. lesteri in northwestern Fujian. Population density was monitored by the night trapping method with outdoor human-baited net at the monitoring sites of malaria vector in Nanping from June to October in 2014-2017. Results In 2011-2017, 3 006 An. sinensis mosquitoes were captured at 68 sites in 10 counties in Nanping and Sanming, but no An. lesteri was found. In 2014-2017, the mean biting rate was 4.33 mosquitoes/person·night at the monitoring sites in Nanping. Conclusion Anopheles sinensis is the only malaria vector found in the historical distribution areas of An. lesteri in northwestern Fujian. But its biting rate is still high. The malaria vector surveillance should be strengthened by the local health authority.

摘要: 目的 了解福建省雷氏按蚊历史分布区传播疟疾媒介种类情况,为巩固当地消除疟疾成果制定媒介防治措施提供依据。方法 2011-2017年每年5-10月蚊媒活动季节,采用诱捕法和全搜捕法在福建省雷氏按蚊历史分布区闽西北的南平和三明市开展疟疾媒介种类调查, 2014-2017年每年6-10月,在南平市疟疾媒介监测点采用夜间通宵室外人帐诱捕法开展媒介按蚊种群密度监测。结果 2011-2017年在南平和三明市共调查10个县、68个调查点,仅捕获3 006只中华按蚊,未发现雷氏按蚊。2014-2017年南平市监测点中华按蚊平均叮人率为4.33只/(人·夜)。结论福建省雷氏按蚊闽西北历史分布区目前疟疾媒介有中华按蚊,其叮人率仍然较高,提示当地卫生部门仍需进一步加强疟疾媒介监测工作。
