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.
