Fig. 1From: Vector competence of northern European Culex pipiens biotypes and hybrids for West Nile virus is differentially affected by temperatureVector competence and titers of WNV injected Cx. pipiens biotype pipiens females over 35 days. Infection (squares) and transmission (triangles) rates of biotype pipiens females incubated at 23 °C from day 0 to 35 post-injection (a). Each data point represents 16–24 mosquitoes. WNV titers of five selected female mosquitoes at each time point from day 0 to 35 post-infection (b)Back to article page
