西双版纳澜沧江河谷竹林蚊类群落学特征的初步研究

为了解热带竹林的蚊类群落学特征和继续探讨蚊类群落学的调查和分析方法，采用随意全捕积水较久树桩内蚊幼，并对调查资料进行群落学特征分析的方法开展研究，共发现库蚊亚科和巨蚊亚科的8属，14亚属，23种蚊虫；分析显示各蚊各上的优势度均较低；优势种侧白伊蚊、圆斑伊蚊和幼小库蚊的优热度仅分别是26.22、25.26和23.74；群薄的Shannon-Wiener多样性指数和均匀性指数分别为2.45和0.78。结论为此群薄蚊种丰富，但无任何蚊种占绝对优势，群落稳定性差。

THE STUDY ON MOSQUITO COMMUNITY CHARACTERISTICS IN BAMBOO FORESTS OF LANCANGJIANG RIVER VALLY,XISHUANGBANNA

In order to understand mosquito community characteristics in tropical bamboo forests and to continuously explore investigatory and analytic methods of mosquito community,the study was undertaken by collecting all mosquito larvae in stumps with long caught water,and analyzing the data for the indices of community characteristics.In the community,we found 23 species,14 subgenera,8 genera of subfamilies Culicinae and Toxorhynchitinae.The results of analysis showed that the dominance of each species was relatively low.The dominance of Aedes albolateralis,A.annandalei and Culex infantulus, which were dominant species,were only 26.22,25.26 and 23.74 respectively.The Shannon Wiener diversity and homogeneity indexes were respectively 2.45 and 0.78.The conclusion was that the community had abundant species,however none was absolutely dominant,and the stability of the community was poor.
