Human activities and land use changes have a major impact on the distribution and diversity of mosquito vectors and their associated viruses. This study describes the diversity and differential abundance of viruses associated with mosquito species from four habitats of the Yucatan Peninsula, Mexico. Using next-generation sequencing (NGS), we analyzed 61 genomic libraries belonging to 20 mosquito species to characterize the viral community. A total of 16 viral species were identified, representing 14 different viral families. Most identified viruses were associated with insects, plants, and fungi. Additionally, vertebrate associated viral families, including , , , and , were detected in mosquitoes from urban habitats. Notably, insect-associated viruses like and were identified, along with the first report of in Mexico. Variations in viral community composition were primarily driven by mosquito species, with species of the same genus maintaining similar viromes despite occupying different habitats. These findings reinforce that intrinsic traits of mosquito species play a key role in shaping viral community composition. To our knowledge, this is the first study that describes the viral community in mosquitoes in Yucatan Peninsula, Mexico. This study provides essential baseline data for the surveillance of mosquitoes and associated viruses from a biodiverse tropical region that faces strong land use modifications.
人类活动和土地利用变化对蚊媒及其相关病毒的分布和多样性有重大影响。本研究描述了来自墨西哥尤卡坦半岛四个栖息地的蚊种相关病毒的多样性和差异丰度。利用下一代测序（NGS）技术，我们分析了属于20种蚊种的61个基因组文库，以表征病毒群落。共鉴定出16种病毒，分属于14个不同的病毒科。大多数鉴定出的病毒与昆虫、植物和真菌有关。此外，在城市栖息地的蚊子中检测到了与脊椎动物相关的病毒科，包括 、 、 和 。值得注意的是，鉴定出了如 和 等与昆虫相关的病毒，以及墨西哥首次报道的 。病毒群落组成的变化主要由蚊种驱动，同一属的蚊种尽管栖息在不同的栖息地，但仍保持相似的病毒组。这些发现强化了蚊种的内在特征在塑造病毒群落组成中起关键作用这一观点。据我们所知，这是第一项描述墨西哥尤卡坦半岛蚊子病毒群落的研究。本研究为来自面临强烈土地利用变化的生物多样热带地区的蚊子及相关病毒监测提供了重要的基线数据。
