目的了解菲律宾塔克洛班市海啸后蚊虫种群构成、密度及吸血情况,为灾区开展蚊虫防制工作提供依据和经验。方法采用二氧化碳诱蚊灯诱捕法、人帐诱捕法、勺捕法和容器检查法开展调查,对吸血蚊虫进行PCR血源分析。结果共捕获成蚊1925只,分为3属5种,其中三带喙库蚊占98.76%为当地优势种、常形曼蚊占0.26%、棕头库蚊占0.26%、带足按蚊占0.36%、嗜人按蚊占0.36%。在捕获的成蚊中吸血蚊虫为10只占0.65%,PCR检测1只吸血蚊体内猪血阳性,1只体内猪、人血均阳性。结论当地具备乙脑传播流行的条件,应关注乙脑的发生流行。
Objective To understand the population structure, density and blood-sucking of mosquitoes after the tsunami in Tacloban, Philippines, to provide basis and experience for mosquito control in disaster-stricken areas. Methods Carbon dioxide mosquito trap method, human trap method, scoop method and container inspection method were used to investigate the blood samples of blood-sucking mosquitoes. Results A total of 1925 adult mosquitoes were captured and divided into 3 genera and 5 species. Among them, 98.76% were Culex tritaeniorhynchus, dominant species, 0.26% 0.36%, Anopheles anthropophagus 0.36%. Among the captured mosquitoes, 10 were mosquitoes, accounting for 0.65%. One swine blood test was positive for swine blood by PCR and one pig was positive for human blood. Conclusion The local conditions for the spread of Japanese encephalitis should pay attention to the prevalence of Japanese encephalitis.
