Genealogical relationships of Ae. aegypti based on the median-joining haplotype network of 3 mitochondrial fragments: cox1 (a); nad4 (b) and nad5 (c). Each line in the network represents a single nucleotide mutation. The size of the nodes corresponds to the frequency of the haplotypes. Colours indicate the collection regions: Group 1 (red), Group 2 (blue), and Group 3 (purple)
