Maximum likelihood tree of candidate odorant receptor (OR) proteins from R. ferrugineus highlighting sex pheromone receptors and aggregation pheromone receptors. ML analysis was computed using MEGA (v.6.0) [42] (JTT model for ML heuristic searches methods was Nearest-Neighbor-Interchange). Insect ORs: T. castaneum, M. caryae, D. ponderosae and I. typographus were used for the construction of the tree. Functionally characterized moth pheromone receptors (B. mori, O. scapulalis, M. sexta, S. exigua, Cydia pomonella, P. xylostella and H. virescens) were included in the tree construction and PR clade is highlighted. R. ferrugineus ORs transcripts and nodes are marked with red color. M. caryae aggregation pheromone receptors and nodes are marked with blue color. The branch containing D. melanogaster Orco was used as outgroup to root the tree. The M. caryae aggregation PR [24] is highlighted with yellow and moth PR with green color. GenBank accession nos are indicated. Scale 0.5 amino acid substitutions per site
