Phylogenetic analysis of olfactory receptor (OR) proteins of nine parasitoid wasps. (a) Maximum likelihood OR protein tree with branches coloured by nine parasitoid wasp species. Scale bar represents 0.5 mean substitutions per site. (b) To the left is a cladogram of nine parasitoid wasps showing estimated number of OR gene gain and loss events along branches and estimated size of ancestral and extant species OR repertoires highlighted in grey. To the right is a bar chart showing the number of each OR subfamilies.
