Detection And Characterization of Insecticide Resistance Mechanisms in Culex Tarsalis
… and West Nile virus. Anopheles gambiae and Culex quinquefasciatus are just two examples of mosquito vectors that possess genetic mutations (denoted kdr and ace-1 ) and/or enhanced detoxifying enzymes (oxidases, esterases, and glutathione-s-transferases) that confer insecticide resistance. …

A cytogenetic map for the genomic studies of the West Nile Virus vector Culex tarsalis
Culex tarsalis is a major vector of West Nile Virus (WNV) in North America. Although the genome for this species was recently sequenced, the physical genome map has not developed. Unlike other Culex species, that have sex-determination locus on chromosome 1, the sex locus in Cx. tarsalis is located …

Modeling Culex tarsalis Coquillett abundance on the northern Colorado Front Range using a landscape-level approach
… Weld and Larimer counties during 2003-2011. Culex tarsalis Coquillett is recognized as the primary species of concern in the transmission of WNV to humans along the northern Colorado Front Range. Before implementing the tools needed to control the spread of a vector-borne disease, public …

Filarial infection in mosquitoes of Northern California
… Anopheles franciscanus, Anopheles freeborni, Culex stigmatosoma, and Culex tarsalis mosquito pools. Due to the presence of D. immitis, which can lead to chronic illness and death in domestic dogs, in Lake County it is important to evaluate vector competency of D. immitis in mosquito species. …

Linking mosquito midgut and virus population biology at the molecular and cellular level
… virus infection dynamics are scarce, and in Culex tarsalis - the primary vector of West Nile virus (WNV) in the contiguous United States - nonexistent. We performed single-cell RNA sequencing on dissociated, WNV-infected Cx. tarsalis midguts. We identified populations of distinct midgut …

Evolutionary influences on the reduction in enzootic circulation and human incidence of western equine encephalitis
… mutations have a competitive advantage in Culex tarsalis and possibly house sparrows. Additionally, these mutations have no effect on virulence in the Syrian golden hamster. Given this data I propose that the mutations WEEV has accumulated by positive selection only enhance this ability to …

Transmission of western equine encephalitis virus by Saskatchewan mosquitoes and behavior of the virus in selected laboratory vertebrates in relation to epidemiological studies
… for their ability to transmit WEE virus by bite. Culex tarsalis was a very efficient transmitter at 69 and 75°F. This mosquito transmitted from four days after infection and remained infective for up to 44 days, which was the longest period of observation. Throughout this period, infection rates …
