Host-feeding patterns of suspected West Nile virus mosquito vectors in Delaware, 2001-2002
TLDR
Paucity of data on host-feeding patterns and behavior of 43 mosquito species that are reported as suspected West Nile virus (WN) vectors has limited full evaluation of their vectorial capacity, and Culex salinarius appear to be the most likely bridge vectors.Abstract:
Paucity of data on host-feeding patterns and behavior of 43 mosquito species that are reported as suspected West Nile virus (WN) vectors has limited full evaluation of their vectorial capacity. Recent studies addressing this issue need additional confirmation and should also be expanded to include collections of species or subpopulations attracted to humans. We used 4 types of collection methods to collect mosquitoes, including omnidirectional Fay–Prince traps, Centers for Disease Control–type light traps, gravid traps, and human-landing collections. Mosquitoes were collected during 2 full WN transmission seasons in 2001 and 2002, at 9 different sites across Delaware. We collected from various habitats, including salt marshes, brackish water areas, woodlands, a tire dump, a racetrack, and a mushroom farm. Blood-meal analyses were performed on parous mosquitoes by using a sandwich-type enzyme-linked immunosorbent assay. We tested primarily for 5 common host species, including rabbits, dogs, deer, ...read more

TL;DR: A temporal analysis of the feeding patterns of the dominant Culex species did not support a shift in feeding behavior away from robins to mammals late in the summer, but a significant degree of temporal variation was noted in the proportion of robin-derived bloodmeals when the data were analyzed by semi-monthly periods, consistent with the hypothesis that the mosquitoes were preferentially feeding upon nesting birds.

Host-Feeding Patterns of Potential Mosquito Vectors in Connecticut, USA: Molecular Analysis of Bloodmeals from 23 Species of Aedes, Anopheles, Culex, Coquillettidia, Psorophora, and Uranotaenia
TL;DR: The white-tailed deer serves as the main vertebrate host for these mammalophilic mosquitoes in this region of the United States, and this feeding pattern supports enzootic amplification of arboviruses, including Jamestown Canyon, Cache Valley, and Potosi viruses that perpetuate in cervid hosts.

TL;DR: Mosquitoes within the Culex pipiens complex have been implicated as major vectors of West Nile virus in North America due to their seasonal abundance, vector competence and high field infection rates, but the role of Cx.

TL;DR: In determining the potential for a mosquito species to become involved in transmitting WNV, it is necessary to consider not only its laboratory vector competence but also its abundance, host-feeding preference, involvement with other viruses with similar transmission cycles, and whether WNV has been isolated from this species under natural conditions.
