2005年和2006年7 ~ 9月，在云南省西北部北纬24 ° 00 ′ ~ 29 ° 00 ′之间海拔900-3280 m范围内，对蚊媒昆虫种类和蚊媒病毒进行了调查。采用紫外灯诱捕法在59个点共采集到蚊虫45属15种54,879只。三带喙库蚊和中华按蚊数量最多。蚊虫密度和物种多样性随海拔升高而降低。使用细胞培养物对代表所有15个物种的281个池中的总共21 008只蚊子进行了病毒检测。鉴定的病毒包括日本脑炎病毒（13个分离株）、Getah病毒（5个分离株）、Banna病毒（3个分离株）、Kadipiro病毒（5个分离株）和浓核病毒（7个分离株）。这些分离株来自三带喙库蚊（20个分离株）、中华按蚊（3个分离株）、近白阿蚊（6个分离株）、致倦库蚊（2个分离株）和未鉴定的混合蚊（2个分离株）。大多数分离物来自海拔2,500米以下的采集。
From July to September in 2005 and 2006, a survey was conducted to identify mosquito species and mosquitoborne arboviruses at elevations ranging from 900-3280 m between 24 degrees 00' N and 29 degrees 00' N latitude in the northwestern part of Yunnan Province, China. A total of 54,879 mosquitoes representing 15 species and 4 genera was collected using UV light traps at 59 sites. Culex tritaeniorhynchus and Anopheles sinensis were the most abundant species. The density of mosquitoes as well as the diversity of species decreased with increasing altitude. A total of 21,008 mosquitoes in 281 pools representing all of the 15 species was tested for the presence of viruses using cell culture. Viruses identified included Japanese encephalitis virus (13 isolates), Getah virus (five isolates), Banna virus (three isolates), Kadipiro virus (five isolates), and Densovirus ( seven isolates). These isolates were obtained from Culex tritaeniorhynchus (20 isolates), Anopheles sinensis (three isolates), Armigeres subalbatus (six isolates), Culex pipiens quinquefasciatus (two isolates), and from unidentified, mixed mosquitoes (two isolates). Most of the isolates were from collections made at elevations below 2,500 m.
