Wild birds have been identified as reservoirs of many pathogens transmissible to humans through bird-biting mosquitoes. Understanding the diversity of vector fauna in bird-conservation areas, is a cornerstone to later develop early detection systems and reduce the risk of emerging disease incidence. Prek Toal is a bird Sanctuary in the Tonle-Sap area in Cambodia hosting the largest migratory bird colony of southeast Asia. The Culicidae fauna was investigated during both dry and rainy seasons. In total, 8,224 mosquitoes from 6 genera and 25 species were collected. The two most represented genera were Anopheles (8 species) and Culex (11 species), while the dominant species was Culex vishnui (58.8%). During the rainy season, 1.6 fold more mosquitoes were caught and the number of species doubled. One of the most notable feature is the absence of any Aedinii mosquito which could be attributed to the low human density around the area, and the large populations of migratory birds. A total of 13 species from 3 genera are reported to be of medical importance. 6 medically-important species were collected in all 3 sites, and are known to bite both wild birds and humans: An. barbirostris, An. campestris, Cx. bitaeniorhynchus, Cx. vishnui, Ma. indiana and Ma. uniformis. One of the most important feature is the over-abundance of Culex vishnui, largely dominant in Prek Toal throughout the seasons and the sites, and being present everywhere in Cambodia. This finding stresses its potentiality to act as bridge vectors in the case of new disease emergence.

野生鸟类已被确定为许多病原体的宿主，这些病原体可通过咬鸟的蚊子传播给人类。了解鸟类保护区内病媒动物群的多样性，是日后开发早期检测系统和降低新发疾病发病风险的基石。Prek Toal 是柬埔寨洞里萨湖地区的一个鸟类保护区，拥有东南亚最大的候鸟群。在旱季和雨季都对库利科动物群进行了调查。共收集到 6 属 25 种 8,224 只蚊子。最具代表性的两个属是按蚊（8种）和库蚊（11种），而优势种是库蚊（Culex vishnui）(58.8%)。在雨季，蚊子数量增加了 1.6 倍，物种数量增加了一倍。最显着的特征之一是没有任何Aedinii蚊子，这可能是由于该地区人口密度低，以及候鸟数量众多。据报道，共有 3 个属的 13 个物种具有医学重要性。在所有 3 个地点都收集了 6 种医学上重要的物种，已知它们会咬野生鸟类和人类：An. barbirostris，一种。油菜，CX。bitaeniorhynchus，CX。维什努伊，马。印第安纳州和马。制服。最重要的特征之一是过度丰富Culex vishnui，在整个季节和地点主要在 Prek Toal 占主导地位，并且在柬埔寨随处可见。这一发现强调了它在新疾病出现的情况下作为桥梁载体的潜力。
