Fig. 8From: Antennal transcriptome analysis of olfactory genes and characterizations of odorant binding proteins in two woodwasps, Sirex noctilio and Sirex nitobei (Hymenoptera: Siricidae)Candidate ionotropic receptors (IRs) of Hymenoptera (purple), Diptera (green), Lepidoptera (orange), Coleoptera (blue), Blattaria (pink) and Orthoptera (black) are displayed in a neighbor-joining phylogenetic tree. The IR8a lineage, IR25a lineage, and NMDA lineages have been labelled. SnocIRs and SnitIRs are marked with red and blue arrows, respectivelyBack to article page
