Geographic distribution of w Pip groups in the World (A) and in Europe (B). Numbers in the maps correspond to locality numbers in Additional file 1: Table S1. Bars and dots represent natural populations and laboratory strains, respectively. The bars show the prevalence of wPip group: blue, wPip-I infection; green, wPip-II; yellow, wPip-III; pink, wPip-IV; orange, wPip-V; black, undetermined group. On Figure 2A, Culex pipiens pipiens form pipiens and Culex pipiens pipiens form molestus = light blue; Cx. p. pallens = light green and Cx. quinquefasciatus = light pink (modified after Farajollahi et al. 2011). On Figure 2B, both Cx. p. pipiens form pipiens and Cx. p. pipiens form molestus are widespread in Europe. Details on sample size, prevalence and Cx. pipiens complex taxa are given in Additional file 1: Table S1.
