摘要
目的了解苏州市消除疟疾后传疟媒介种群及密度现状,为消除疟疾后输入性疟疾引起本地继发感染的风险评估提供参考依据。方法选择2019年6-10月苏州市所辖7个县(区),采用全通宵诱蚊灯法和半通宵人诱法进行按蚊种群和密度监测;在水稻田及周边灌溉水体等环境用500 mL勺取20勺水观察按蚊幼虫密度。结果苏州市2019年6-10月全通宵诱蚊灯法室内共捕获中华按蚊40只,密度为0.19只/灯·夜,外捕获中华按蚊44只,密度为0.21只/灯·夜;2019年6-10月半通宵人诱法共捕获中华按蚊89只,平均叮人率为0.21只/人·h;2019年6-10月份水稻田及周边环境中华按蚊幼虫密度为0.37条/勺。结论消除疟疾后,苏州市的传疟媒介主要是中华按蚊,未监测到嗜人按蚊的存在;2019年6-10月中华按蚊的密度低于往年。
OBJECTIVE To understand the status of malaria-borne vector population and density after elimination of malaria in Suzhou,and to provide a reference basis for risk assessment of local secondary infections caused by imported malaria after elimination of malaria. METHODS From June to October 2019,7 counties(districts)under the jurisdiction of Suzhou City were selected to monitor the population and density of Anopheles mosquitoes by the all-night mosquito trapping method and the half-night human trapping method;500 ml was used in the paddy field and surrounding irrigation water bodies and other environments. 20 scoops of water were applied to observe the density of Anopheles larvae. RESULTS A total of 40 Anopheles sinensis were captured indoors in Suzhou from June to October in 2019,with a density of 0.19/(light · night),and 44 Anopheles sinensis were captured outside,with a density of 0.21/(light · night). A total of 89 Anopheles sinensis were captured by semi-overnight human lure in June-October 2019,with an average biting rate of 0.21/(person · h). The density was 0.37 bars/spoon with larvae of Anopheles sinensis in rice fields and surrounding environment in June-October 2019. CONCLUSION After the elimination of malaria,the main vectors of malaria in Suzhou were Anopheles sinensis,and the presence of Anopheles anthropophagus was not detected. The density of Anopheles sinensis in June-October 2019 was lower than previous years.
