Abstract: Objective To analyze the vector surveillance results during the stage of malaria elimination, so as to provide the evidence for assessing the local transmission risk of imported malaria and carrying out the surveillance work after malaria elimination in Jiangsu Province. Methods From 2011 to 2017, the mosquito population was monitored and human biting rates were calculated by the half overnight human baiting trapping method and overnight lamp trapping method in 7 surveillance sites from June to October. The insecticide resistance level was tested by the force contact method recommended by WHO. Results A total of 5 106 Anopheles mosquitoes were captured by the half over?night human baiting trapping method in the 7 sites from 2011 to 2017, and all the mosquitoes were identified as Anopheles sinensis. The annual human biting rates were 1.075, 0.786, 1.057, 0.787, 0.790, 1.797 and 1.185 mosquitoes/(human·hour), respectively. Totally 28 186 Anopheles mosquitoes were caught by the overnight lamp trapping method, and all the mosquitoes were An. sinensis. The densities of Anopheles mosquitoes were 57.950, 50.932, 14.800, 4.405, 58.070, 72.406, and 17.145 mosquitoes/(night·lamp), respectively. In 2012, the resistance indexes of An. sinensis to deltamethrin, DDT and malathion were at R level in Jiangsu Province. Conclusions The major vector is An. sinensis and no An. anthropophagus is found in Jiangsu Province. An. sinensis has a high level of resistance to deltamethrin, DDT and malathion.

摘要: 目的 分析江苏省消除疟疾阶段媒介监测结果,为输入性疟疾在本地传播的风险评估和消除疟疾后监测提供科学依据。方法 2011-2017年每年6-10月,在江苏省媒介按蚊监测点采用半通宵人饵诱捕法、室外全通宵诱蚊灯法诱捕按蚊,进行按蚊种群和密度监测;采用WHO推荐的强迫接触筒法进行杀虫剂抗性监测。结果 2011-2017年,在江苏省7个媒介按蚊监测点采用半通宵人饵诱捕法共捕获中华按蚊5 106只,年均叮人率分别为1.075、0.786、1.057、0.787、0.790、1.797只/(人·h)和1.185只/(人·h);采用室外全通宵诱蚊灯法共捕获中华按蚊28 186只,年均灯诱密度分别为57.950、50.932、14.800、4.405、58.070、72.406只/(灯·夜)和17.145只/(灯·夜)。2012年中华按蚊对溴氰菊酯、DDT和马拉硫磷的敏感性、抗性指数均为R级。结论 江苏省传疟媒介主要为中华按蚊,未发现嗜人按蚊;部分疟疾流行区中华按蚊已对溴氰菊酯、DDT和马拉硫磷产生高度抗性。
