本研究的目的是调查吸血来源的蚊子捕获在城市的圣保罗，巴西的市政公园，并确定蚊子的物种和他们的食物偏好之间可能的关联。利用PCR方法对510只饱血的成年雌蚊的14种血液宿主进行了鉴定，所用引物为基于细胞色素B线粒体DNA的脊椎动物特异性引物组，包括鸟、狗、猫、啮齿类动物、人类和其他灵长类动物。使用手动抽吸器、树冠中的CDC诱捕器、地面水平的CDC诱捕器和香农诱捕器捕获蚊子。除了猫之外，所有其他脊椎动物都被公园里的蚊子用作宿主。统计分析未能显示任何趋势之间的关联大多数culicid捕获的物种和血餐的来源。相反，他们揭示了随机模式，表明蚊子以最丰富或最方便的血餐来源为食。虽然在两个物种（鸟类的情况下，Cx。在Cx的情况下，nigripalpus和狗。quinquefasciatus），我们的研究结果突出了本研究中雌性蚊子的机会性摄食习性。
The aim of this study was to investigate blood meal sources of mosquitoes captured in municipal parks in the city of Sao Paulo, Brazil, and to identify possible associations between mosquito species and their food preferences. Fourteen species of blood hosts of 510 engorged adult female mosquitoes were identified using PCR assays with a vertebrate-specific primer set based on cytochrome b mitochondrial DNA of the following vertebrates: birds, dogs, cats, rodents, humans, and other primates. Mosquitoes were captured using a manual aspirator, CDC traps in the canopy, CDC traps at ground level, and Shannon traps. With the exception of cats, all other vertebrates were used as hosts by mosquitoes in the parks. Statistical analysis failed to show any trend toward association between most culicid species captured and the sources of blood meals. Instead, they revealed random patterns, indicating that the mosquitoes fed on the most abundant or convenient blood meal sources. Although feeding preferences were observed in two species (birds in the case of Cx. nigripalpus and dogs in the case of Cx. quinquefasciatus), our results highlight the opportunistic feeding habits of the female mosquitoes in this study.
