Abstract: Objective To study on the mosquito community characters of in-village and field in Xishuangbanna,Yunnan.Methods A series of ecological methods are involved in this paper about community characters,diversity and similarity.To collect mosquito with human-bait,and cattle-bait in 8 m× 8 m× 2 m mosquito net.Results 36 species,11 subgenus,6 genus,2 subfamillies in-village,38 species,10 subgenus,4 genus,2 subfamillies in field were collected.The dominant species included Cx.tritaeniorhynchus,Cx.fuscocephala,Cx.psedoviishnui,An.sinensis,An.philipinensis,An.crawfordi,An.aconitus and An.kochi.In village,their dominance were 70.73,31.37,29.92,36.11,25.67,27.80,21.60,15.58,and in-field their dominance were 58.18,31.86,29.13,34.91,16.55,26.77,24.06,21.45.In-village,the index of Shannon-Winner diversity was 1.78,the homogenous index was 0.45 and concentrating index of dominance was 0.83,in the field the index of Shannon-Winner diversity was 2.09,the homogenous index was 0.58,and concentrating index of dominance was 0.81.Conclusion The field community was more abundant than in-village community,and its structure and component were very complicated,the distribution of dominant species was relatively stable.
