Figure 3From: Understanding West Nile virus ecology in Europe: Culex pipiens host feeding preference in a hotspot of virus emergence Culex pipiens feeding preferences for most abundant bird species. Feeding preference indexes (P i ) of Cx. pipiens mosquitoes and 95% confidence interval for the eight most abundant bird species in the Veneto region. Positive values are preferences; negative values designate avoidance and are calculated as (-1/P i ). Species marked ‘#’ are calculated as conservative estimates (see text).Back to article page
