充血的 Coquillettidia perturbans、Psorophora ferox、Culex、Culiseta 和 Aedes 蚊子主要通过扫网从美国康涅狄格州的盐沼和林地栖息地收集。在测试的 570 只蚊子中，沉淀素测试确定了 517 种血粉的来源，并揭示了不同的宿主进食模式。伊蚊主要以哺乳动物为食； A. abserratus、A. cantator 和 A. vexans 对牛和/或马表现出选择性。 A. cantator 还从鸟类宿主中获取血液，并且在某些情况下，显示出雀形目动物和哺乳动物的混合血粉。这些发现增加了这种盐沼蚊子传播东部马脑脊髓炎病毒的媒介潜力。黑蚊以鹿为食表明这种蚊子可能参与加州脑炎某些亚型的传播。淡色库蚊、雷氏库蚊、黑库蚊和库蚊。 morsitans dyari 几乎完全从雀形目鸟类获取血液。
Blood-engorged Coquillettidia perturbans, Psorophora ferox, Culex, Culiseta and Aedes mosquitoes were collected principally by sweep net from salt marsh and woodland habitats in Connecticut, USA. Of the 570 mosquitoes tested, precipitin tests identified the origins of 517 blood meals and revealed distinct host feeding patterns. Aedes mosquitoes fed chiefly on mammals; A. abserratus, A. cantator and A. vexans showed selectivity for cattle and/or horses. A. cantator also obtained blood from avian hosts and, in some instances, showed mixed passerine-mammal blood meals. These findings increase the vector potential of this salt marsh mosquito for eastern equine encephalomyelitis virus. Feedings on deer by A. abserratus suggest potential involvement of this mosquito in the transmission of certain subtypes of California encephalitis. Culex pipiens, C. restuans, Culiseta melanura, and Cs. morsitans dyari acquired blood almost exclusively from passeriform birds.
