Abstract:
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.
摘要:
蚊子(双翅目:Culicidae)是世界上研究最多的节肢动物群体之一,因为它们对病原体的传播能力很高,包括病毒和寄生虫.在2022年6月至10月期间,使用带有紫外线的诱捕器调查了来自中国湖南省12个代表性行政区的12个集约型猪场中蚊子的流行情况。对所有收集的蚊子进行计数并根据形态学和分子方法鉴定物种。猪场共收集了4443个蚊子样本,他们代表一个家庭,四属九种。淡色库蚊(24%)是最常见的蚊类,其次是阿尔米格雷斯(23.4%)和三带囊库蚊(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都分为不同的单系组,对应于9种已知的蚊子,并得到了强有力的支持。本调查结果对湖南省养猪场蚊虫感染的持续控制具有重要意义。中国。这是湖南省集约化养猪场蚊子种群的首次报道,中国。
