Vector 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)
