The maximum-likelihood phylogeny of insect CO2 receptor proteins. Three CO2 receptor proteins identified from D. v. virgifera (Dvv) were compared against orthologous proteins from T. castaneum (Tcas), D. melanogaster (Dmel), and A. gambiae (Agam). For the T. castaneum proteins, the naming convention proposed by Robertson and Kent [11] is used. The phylogeny is the consensus tree based on bootstrap analysis with 1000 pseudoreplicates. The numbers at nodes show the bootstrap supporting values (%)
