In the Old World, some mosquitoes in the Culex pipiens complex are excellent enzootic vectors of West Nile virus, circulating the virus among birds, whereas others bite mainly humans and other mammals. Here we show that, in northern Europe, such forms differing in behavior and physiology have unique microsatellite fingerprints with no evidence of gene flow between them, as would be expected from distinct species. In the United States, however, hybrids between these forms are ubiquitous. Such…

The Arrival of the Northern House Mosquito Culex pipiens (Diptera: Culicidae) on Newfoundland's Avalon Peninsula

Abstract Culex pipiens L., the northern house mosquito, is the primary vector of West Nile virus to humans along the east coast of North America and thus the focus of much study. This species is an

Culicids on the move: a genetic characterization of two mosquito disease vector species in eastern insular Newfoundland

Results of this study indicate a level of genetic diversity within the recently discovered Newfoundland population comparable to populations in other regions and a general lack of structure between Canadian populations and those in Europe.

Microsatellite loci from the northern house mosquito ( Culex pipiens ), a principal vector of West Nile virus in North America

Microsatellites were isolated and characterized in the northern house mosquito, Culex pipiens, a widespread pest species and important vector of diseases such as West Nile virus, and will be useful for studies of population structure and intraspecific variation in epidemiological characteristics.

Vector Competence of North American Mosquitoes (Diptera: Culicidae) for West Nile Virus

The potential for several North American mosquito species to transmit the newly introduced West Nile (WN) virus is evaluated, and laboratory vector competence, host-feeding preferences, relative abundance, and season of activity determine the role that these species could play in transmitting WN virus.

Clinicians are advised to consider WNV as a differential diagnosis, especially in patients over 50 years old with a clinical picture of viral encephalitis or aseptic meningitis presenting in the summer months, because of insufficient information on the ecology of the virus, and on mosquito populations, to accurately determine this risk.

It was found that significant differences in biological traits exist between mosquitoes from different habitats, characteristics of the commensal type are not universal in mosquitoes from underground man-made habitats, and allozyme markers do not clearly differentiate ecotypes.
