Fig. 3From: Vector competence of northern European Culex pipiens biotypes and hybrids for West Nile virus is differentially affected by temperatureWNV titers of orally infected Cx. pipiens females with virus-positive bodies and saliva. WNV titers were determined after 14 days of incubation at 18, 23, or 28 °C for biotype pipiens (a), biotype molestus (b) and hybrids (c). Horizontal black lines show median titers at each temperatureBack to article page
