Phylogenetic analysis of ORs. Species abbreviations: Cfor, Cylas formicarius; Tcas, Tribolium castaneum; Mcar, Megacyllene caryae; Ityp, Ips typographus; Dpon, Dendroctonus ponderosae; Cbow, Colaphellus bowringi. Branch support (circles at the branch nodes) was estimated using an approximate likelihood ratio test based on the scale indicated at the top left. Bars indicate branch lengths in proportion to amino acid substitutions per site.
