全球变暖有可能增加蚊子传播疾病的传播和流行。某些病原体可由候鸟携带并传播给当地的蚊子种群。在菲律宾北部的鸟类迁徙季节收集了蚊子，以检测禽疟寄生虫，并鉴定潜在的媒介物种和估计当地蚊子种群的感染情况。采用巢式PCR检测禽疟的种类。vishnui库蚊（47.6%）是最丰富的物种；其次是三带喙龙（13.8%）。在8种蚊中检出禽疟原虫，感染率在0.5% ~ 6.2%之间。本研究发现的6个疟原虫遗传谱系包括P.近核疟原虫-GALLUS02、Tacy7 （Donana04）、CXBIT01、新西兰疟原虫LIN2和2个未分类谱系。菲律宾禽疟原虫潜在传播媒介为Cq。凤眼莲,残雪。fuscocephala,残雪。quinquefasciatus,残雪。sitiens,残雪。毗瑟奴和马。均匀化;两个主要的遗传谱系，P.近核和Tacy7。
Global warming threatens to increase the spread and prevalence of mosquito-transmitted diseases. Certain pathogens may be carried by migratory birds and transmitted to local mosquito populations. Mosquitoes were collected in the northern Philippines during bird migration seasons to detect avian malaria parasites as well as for the identification of potential vector species and the estimation of infections among local mosquito populations. We used the nested PCR to detect the avian malaria species. Culex vishnui (47.6%) was the most abundant species collected and Cx. tritaeniorhynchus (13.8%) was the second most abundant. Avian Plasmodium parasites were found in eight mosquito species, for which the infection rates were between 0.5% and 6.2%. The six Plasmodium genetic lineages found in this study included P. juxtanucleare -GALLUS02, Tacy7 (Donana04), CXBIT01, Plasmodium species LIN2 New Zealand, and two unclassified lineages. The potential mosquito vectors for avian Plasmodium parasites in the Philippines were Cq. crassipes, Cx. fuscocephala, Cx. quinquefasciatus, Cx. sitiens, Cx. vishnui, and Ma. Uniformis; two major genetic lineages, P. juxtanucleare and Tacy7, were identified.
