目的了解缅甸北部地区的蚊类种群构成及对蚊类物种多样性进行初步观察。方法2008年8-9月分别在靠近中国边境地区的4个居民点用CDC诱蚊灯捕蚊,对所获蚊虫进行分类计数和对数据进行统计学分析。结果人房共捕获蚊虫2亚科8属17亚属45种2268只,牛房共捕获蚊虫2亚科7属12亚属33种1703只,其中发现人房主要优势蚊种和优势度依次为微小按蚊(58.16)、可赫按蚊(46.27)、伪杂鳞库蚊(45.68)、三带喙库蚊(41.97)、杰普尔按蚊(40.18);牛房主要优势蚊种和优势度分别为可赫按蚊(34.37)、三带喙库蚊(34.30)、微小按蚊(29.13)、美彩按蚊(27.68)。人房、牛房蚊虫的多样性指数和均匀性指数分别为2.61、1.58和2.68、0.48。结论主要疟疾媒介微小按蚊是当地人房的优势种,牛房捕获的微小按蚊绝对数量少于人房。
Objective To understand the population structure of mosquitoes in northern Burma and to observe the mosquito species diversity. Methods From August to September in 2008, mosquitoes were caught in four habitats near the Chinese border by CDC mosquito lamp. The mosquitoes were classified and counted and the data were statistically analyzed. Results A total of 2268 mosquitoes belonging to 45 genera, 8 subfamilies, and 17 subfamilies were captured in the human house. A total of 1703 mosquitoes belonging to 33 genera, 7 subfamilies, 12 subfamilies were captured in the cow house. Among them, dominant dominant mosquito species and dominance were found to be Anopheles minimus (58.16), Anopheles schizophyllum (46.27), Culex pseudomeriae (45.68), Culex tritaeniorhynchus (41.97) and Anopheles jepulus (40.18). The dominant dominant mosquito species and dominance (34.37), Culex tritaeniorhynchina (34.30), Anopheles minimus (29.13), Anopheles anthropophagus (27.68), respectively. The diversity and homogeneity index of human house and house breeder mosquito were 2.61,1.58 and 2.68,0.48 respectively. Conclusion The main malaria vector, Anopheles minimus, is the predominant species in the local people’s houses. The absolute number of Anopheles minimus captured in the cattle house is less than that in the human house.
