目的掌握义乌地区在登革热暴发流行后存在哪些蚊媒传染病主要传播媒介及其地理分布,为科学防控蚊媒传染病主要病媒生物提供理论依据。方法随机抽样调查,蚊幼主要采用勺捕法(Dipper),成蚊使用诱蚊灯法。结果本次蚊虫孳生地调查与成蚊监测,共发现2亚科4属8种。根据光诱捕器监测结果,淡色库蚊是该地区主要优势种,覆盖13个镇(街)234个村。而蚊幼孳生地调查结果显示,白纹伊蚊是该地区唯一的登革热主要传播媒介,主要分布于10个镇(街)18个村,是本次义乌地区登革热大面积暴发流行的助燃剂,占蚊幼采集量的51.7%;其次是三带喙库蚊,而新发现的小拟态库蚊等捕获量有限。结论一些蚊媒传染病主要传播媒介在义乌地区广为分布,部分区域种群密度较高,今后应加强该地区蚊虫孳生地清理工作,从源头上有效切断蚊媒传染病主要传播途径,从而为当地蚊媒传染病传播媒介预防控制工作奠定坚实的理论基础。
Objective To know which mosquito-borne infectious diseases exist in Yiwu after the outbreak of dengue outbreak and its geographical distribution, so as to provide a theoretical basis for the prevention and control of mosquito-borne infectious diseases. Methods A random sample of mosquito larvae was collected by using Dipper and mosquito lamp. Results The survey of mosquito breeding sites and adult mosquitoes showed that there were 8 species of 4 genera in 2 subfamilies. According to light traps monitoring results, Culex pipiens pallens is the dominant species in the area, covering 234 villages in 13 towns (streets). The survey of mosquito breeding sites showed that Aedes albopictus was the only major transmission medium for dengue fever in the area, mainly distributed in 18 villages in 10 towns (streets) Accounting for 51.7% of juvenile mosquito larvae; followed by Culex tritaeniorhynchus, while newly caught Culex pipiens pallens and other trapped species were limited. Conclusion Some major vectors of mosquito-borne infectious diseases are widely distributed in Yiwu, with higher population density in some areas. In the future, it is necessary to strengthen the clean-up of mosquito breeding sites in the area and effectively cut off the main routes of transmission of mosquito-borne infectious diseases from the source, Mosquito-borne infectious disease prevention and control media to lay a solid theoretical foundation.
