Neighbor-joining tree showing the relationships among the human mtDNA haplotypes amplified from mosquitoes.

Each symbol represents one DNA sequence amplified from one mosquito. Different shapes represent different Anopheles species (squares-An. punctulatus s.s., triangles-An. farauti 4) and is colored according to the collection site (green-Dimer, blue-Wasab, purple-Kokofine). Mixed blood meals are highlighted by boxes of the same color: for example, the two red boxes show two human mtDNA haplotypes amplified from a single An. farauti 4 mosquito collected in Kokofine.
