The numbers of GR (gustatory receptor), OR (olfactory receptor), IR (ionotropic receptor), OBP (olfactory binding protein), and CSP (chemosensory protein) genes in T. mercedesae and nine arthropod species including Bombyx mori and Acyrthosiphon pisum are shown. Data refer to references [35, 102, 21] and this study.
