摘要：我们评估了几种蚊子的吸血模式，这些蚊子可能是美国东北部疾病媒介的媒介。在 6 年时间里（2002 年 6 月至 2007 年 10 月）从康涅狄格州 91 个不同地点收集了以血液喂养的蚊子，并通过使用基于聚合酶链反应的测定和对线粒体 DNA 细胞色素 b 基因部分的测序来检查代表 6 个属的 23 种蚊子的宿主喂养模式。这项研究是全州监测计划的一部分，对于某些蚊种，检查了有限数量的标本 [例如，伊蚊 (De Geer) (1)、按蚊 (Anopheles barberi Coquillett) (1)、乌拉诺塔尼亚 (Osten Sacken) (5)]。除了从所有四类脊椎动物（鸟类、爬行动物、两栖动物和哺乳动物）获取血粉的土库蚊之外，发现所有伊蚊、按蚊、Coquillettidia、Psorophora 以及较小程度的 Uranotaenia 都主要以哺乳动物宿主为食。十四种哺乳动物被确定为血液来源，但大部分饲料取自白尾鹿（Odocoileus virginianus）。从 23 种蚊子中的 13 种中鉴定出人类血粉。在加拿大伊蚊 (Theobald)、白伊蚊 (Coquillett)、灰纹伊蚊 (Aedes cinereus Meigen)、三列伊蚊 (Coquillett)、三色伊蚊 (Coquillett) 和 Coquillettidia perturbans (Walker) Cx 中检测到了有限的禽源血粉。 territans、Psorophora ferox (von Humboldt) 和 Ur。萨菲丽娜。美洲知更鸟（Tudus migratorius）是最常见的鸟类血液来源，其次是其他一些主要是雀形目鸟类。我们得出的结论是，白尾鹿是美国该地区这些嗜哺乳动物蚊子的主要脊椎动物宿主。这种进食模式支持虫媒病毒的地方性扩增，包括在鹿科动物宿主中永久存在的詹姆斯敦峡谷病毒、卡什谷病毒和波托西病毒。偶尔以鸟类宿主为食表明其中一些蚊子种类，例如 Cq.扰乱者也可能促进西尼罗河和东部马脑炎病毒从病毒血症鸟类传播到哺乳动物宿主。
Abstract We evaluated the blood-feeding patterns in several mosquito species that may serve as vectors of disease agents in the northeastern United States. Blood-fed mosquitoes were collected from 91 different sites throughout Connecticut over a 6-yr period (June–October 2002–2007), and the host-feeding patterns of 23 mosquito species representing six genera were examined by using a polymerase chain reaction-based assay and sequencing portions of the cytochrome b gene of mitochondrial DNA. This study was part of a statewide surveillance program and for some of the mosquito species a limited number of specimens were examined [e.g., Aedes communis (De Geer) (1), Anopheles barberi Coquillett (1), Uranotaenia sapphirina (Osten Sacken) (5)]. With the exception of Culex territans Walker that acquired bloodmeals from all four classes of vertebrates—birds, reptiles, amphibians, and mammals—all species of Aedes, Anopheles, Coquillettidia, Psorophora, and to a lesser degree, Uranotaenia, were found to feed predominately upon mammalian hosts. Fourteen mammalian species were identified as sources of blood, but the majority of feedings were taken from the white-tailed deer, Odocoileus virginianus. Human-derived bloodmeals were identified from 13 of the 23 mosquito species. Limited avian-derived bloodmeals were detected in Aedes canadensis (Theobald), Aedes cantator (Coquillett), Aedes cinereus Meigen, Aedes triseriatus (Coquillett), Aedes trivittatus (Coquillett), Coquillettidia perturbans (Walker) Cx. territans, Psorophora ferox (von Humboldt), and Ur. sapphirina. American robin, Turdus migratorius, was the most common source of avian blood, followed by a few other mostly Passeriformes birds. We conclude that the white-tailed deer serve as the main vertebrate host for these mammalophilic mosquitoes in this region of the United States. This feeding pattern supports enzootic amplification of arboviruses, including Jamestown Canyon, Cache Valley, and Potosi viruses that perpetuate in cervid hosts. Occasional feeding on avian hosts suggests that some of these mosquito species, such as Cq. perturbans, also could facilitate transmission of West Nile and eastern equine encephalitis viruses from viremic birds to mammalian hosts.
