Figure 5From: Population structure of Bactrocera dorsalis s.s., B. papayae and B. philippinensis (Diptera: Tephritidae) in southeast Asia: evidence for a single species hypothesis using mitochondrial DNA and wing-shape dataHaplotype network of B. dorsalis s.l. collected in southeast Asia. COI haplotype network shaded by site, representing 83 haplotypes for Bactrocera dorsalis complex flies sampled through southeast Asia. Sizes of nodes and pie segments are proportional to haplotype frequency. Small unshaded circles represent median vectors (roughly equivalent to hypothetical unsampled haplotypes). Length of branches is proportional to number of mutational changes between haplotypes.Back to article page
