Association between Wolbachia prevalence and mtDNA haplotype of the G. f. fuscipes host. Association of groELfrom Wolbachia in G. f. fuscipes (wGff) groups with mtDNA haplotype and tsetse infection status from Ugandan populations. The Y-axis shows the number of infected and uninfected flies (black and gray bars, respectively). The X-axis shows the host mtDNA haplotypes (numbers) and haplogropus (white and black bars for the southern and northern mtDNA haplogroups, respectively). An asterisk next to the haplotype number indicates an mtDNA haplotype associated with wGff groEL sequence. Gray shaded mtDNA haplotype numbers indicate those haplotypes found in, but not limited to, collection sites where both northern and southern haplotypes co-occur. A number above the bars identifies the wGff group (1 and 2). P-values above haplotypes indicate whether there are more individuals infected than uninfected for a given haplotype (Binomial test).
