云南中缅边境蚊科昆虫群落的研究

Mosquito Communities in Boarder Areas between China and Burma

为调查和了解云南省瑞丽市中缅边境蚊虫多样性状况，应用灯诱法和采集幼虫法对瑞丽市中缅边境上高丽村和周边方圆4km原始森林内的蚊虫的优势种组成、蚊虫群落结构的集中性指数、多样性指数和均匀度指数进行分析。结果显示，在居民区共采获蚊虫3305只，共5属13种，隶属于蚊科Culicidae中的伊蚊属Aedes、库蚊属Culex、按蚊属Anopheles、曼蚊属Mansonia和阿蚊属Arm函eres。其中优势种蚊虫为三带喙库蚊和中华按蚊。在非居民区共采或蚊虫200只，共5属21种，隶属于蚊科Culicidae中的伊蚊属、库蚊属、按蚊属、巨蚊属Toxorhynchites和蓝带蚊属Uanotaenia。其中优势种蚊虫为白纹伊蚊、拟态库蚊。由于自然环境的破坏，居民区优势集中度过高，群落结构不均匀，非居民区多样性较差，群落内物种的均匀度也偏低。

The mosquito populations were investigated by trap lamps and larva collection in GaoLi village and virgin forests around the village in boarder areas between China and Burma. The results showed that a total of 3305 mosquitoes belonging to 5 genus and 13 species were collected from the populated area, the 5 genus were Aedes, Culex, Anopheles, Mansonia and Armigeres, among these mosquitoes, Cx. tritaeniorhynchus and An. sinensis were the dominant species; While in the virgin forests, a total of 200 mosquitoes belonging to 5 genus and 21 species were sampled, the 5 genus were Aedes, Culex, Anopheles, Toxorhynchites and Uanotaenia, Ae. albopictus and Cx. mimeticus were the dominant species. The population structure was imbalanced at populated areas, and the diversity index of mosquito communities is lower at forests than that is residential area, which might attribute to environmental changes.
