Abstract:		"The oriental fruit moth, Grapholita molesta, is a worldwide pest that damages Rosaceae fruit trees. Sex pheromones play an important role in controlling this pest; however, the corresponding chemosensation mechanism is currently unknown. In this study, 60 candidate odorant receptors, including eight pheromone receptors (PRs), were identified by antennal transcriptome analysis. Expression profiles indicated that most PRs were highly expressed in the males, except GmolOR21 and GmolOR22, which were specifically expressed in the females. Among them, GmolOR2 was identified in response to the main sex pheromone Z8-12:OAc and E8-12:OAc, and its in vivo function was confirmed by RNA interference analysis. Electrophysiological analysis showed that the males had a significantly reduced sensitivity to the main pheromones after the knockdown of GmolOR2. Our research makes a better understanding of pheromone chemoreception and provides a theoretical basis to developing novel, efficient, and environmentally friendly insect attractants"
