Mosquitoes (Diptera: Culicidae) are one of the most studied groups of arthropods worldwide due to their high transmission capacity for pathogens, including viruses and parasites. During June to October 2022, the prevalence of mosquito species in 12 intensive pig farms from 12 representative administrative regions in Hunan province of China was investigated using traps with ultraviolet light. All collected mosquitoes were counted and identified to species according to morphological and molecular methods. A total of 4,443 mosquito specimens were collected in the pig farms, and they represented one family, four genera and nine species. Culex pipiens pipiens (24%) was the most common mosquito species, followed by Armigeres subalbatus (23.4%) and Culex tritaeniorhynchus (20.6%). Phylogenetic analyses based on mitochondrial cox1 sequences revealed all mosquito species from present study grouping into distinct monophyletic groups corresponding to nine known mosquito species with strongly supported. The results of the present investigation have implications for the ongoing control of mosquito infestation in pig farms in Hunan province, China. This is the first report of mosquito populations in intensive pig farms in Hunan province, China.
蚊子（双翅目：蚊科）是全世界研究最多的节肢动物之一，因为它们具有很高的病原体传播能力，包括病毒和寄生虫。2022 年 6 月至 10 月，在中国湖南省 12 个具有代表性的行政区域的 12 个集约化养猪场，使用带有紫外线的诱捕器调查了蚊子物种的流行情况。根据形态学和分子方法，对所有收集到的蚊子进行计数和鉴定到种。在养猪场共收集到 4443 只蚊子标本，它们代表一个科、四个属和九个种。致倦库蚊（24%）是最常见的蚊子种类，其次是白纹伊蚊（23.4%）和三带喙库蚊（20.6%）。基于线粒体 cox1 序列的系统发育分析显示，本研究中的所有蚊子种类都分为不同的单系群，与 9 种已知的蚊子种类形成强烈支持的关系。本研究结果对中国湖南省正在进行的养猪场蚊子感染控制具有重要意义。这是中国湖南省集约化养猪场蚊子种群的首次报告。
