Abstract Olfactory proteins form the basis of insect olfactory recognition, which is crucial for host identification, mating, and oviposition. Using transcriptome analysis Anoplophora glabripennis antenna, we identified 42 odorant-binding (OBPs), 12 chemosensory (CSPs), 14 pheromone-degrading enzymes (PDEs), 1 odorant-degrading (ODE), 37 odorant receptors (ORs), 11 gustatory (GRs), 2 sensory neuron membrane (SNMPs), 4 ionotropic receptor (IR). All CSPs PBPs were expressed in antennae, confirming authenticity data. CSP expression profiles showed that Agla CSP3, CSP6, CSP12 preferentially maxillary palps CSP7 CSP9 strongly antennae. The vast majority highly multiple tissues, suggesting their participation recognition almost all tissues. Intriguingly, PBP AglaPBP2 was indicating it main protein involved efficient sensitive pheromone recognition. Phylogenetic indicated GR1 may detect CO . This study establishes a foundation determining chemoreception molecular mechanisms A. , would provide new perspective controlling pest populations, especially those borers.
