Abstract: Objective:To study on the mosquito communities and the geographical niche of border area inYunnan province.Methods:Alluring by man body in day time and traping by trapper at night.Results:The mosquito communities were investigated in 15 border counties in Yunnan.The results showed that there were 6 dominant species of night-actived mosquitoes around domestic animal and human house in the rural area and 5 dominant species of day-actived mosquitoes in the groves of bamboo and woods.They were:Culex tritaeniorhynchus,Culex pseudovishnui,Culex fuscocephala,Culex whitmorei,Anopheles sinensis,Anopheles vagus,Aedes albopictus,Aedes pseudabopictus,Aedes annandale,Aedes vexans and Armigeres subalbatus.The diversity indexof night-actived mosquito communities were:Cangyuan(2.092 0),Ruili(2.035 5),Yingjiang(1.9521),Jinghong(1.8193),Maguan(1.7234),Genma(1.6857),Mengla(1.6717),Jingping(1.6709),Shuangjiang(1.6488),Menglian(1.6444),Menghai(1.568 8),Wangding(1.4616),Hekou(1.427 1),Luxi(1.2940) and Baoshang(1.2364).The diversity indexof day-actived mosquito communities were:Hekou(2.1630),Jinghong(1.9355),Mengla(1.7447),Cangyuan(1.6756),Genma(1.6734),Yingjiang(1.625 8),Luxi(1.601 5),Wangding(1.594 8),Ruili(1.531 8),Menglian(1.161 9) and Menghai(1.056 1).Conclusion:Thebiggest geographical niche breadth to night-actived mosquitoes wasCulex pipiengsquinquefasciatus(0.858 6),Culex tritaeniorhchus(0.838 2),Culex pseudovishnui (0.8015) and the biggest geographical niche breadth to day-actived mosquitoes wasAedes albopictus(0.895 5).
