Vector Competence of Aedes vexans (Diptera: Culicidae) for West Nile Virus and Potential as an Enzootic Vector

Vector competence of Aedes vexans (Meigen) and Culex pipiens pipiens L. (Diptera: Culicidae) for West Nile virus (family Flaviviridae, genus Flavivirus, WNV) was compared. Infection rates of both species were similar 14 d after feeding on chickens, with WNV titers ranging from 104.2 to 108.7 plaque-...

Zusammenfassung:Vector competence of Aedes vexans (Meigen) and Culex pipiens pipiens L. (Diptera: Culicidae) for West Nile virus (family Flaviviridae, genus Flavivirus, WNV) was compared. Infection rates of both species were similar 14 d after feeding on chickens, with WNV titers ranging from 104.2 to 108.7 plaque-forming units (PFU)/ml. Median infectious doses and 95% confidence intervals (CI) were 106.0(5.8,6.3) and 105.7(5.4,5.9) PFU for Ae. vexans and Cx. p. pipiens, respectively. WNV transmission was not observed in Ae. vexans that fed on chickens with WNV titers
