Research Abstract	We report here the molecular characterization and possible function of the odorant receptor(termed HlOr) identified in the haller's organ of the hard tick Haemaphysalis longicornis. The HlOr was found to be expressed at highest levels in haller's organ, chelicera, midgut and salivary grand of H. longicornis. Immunolocalization studies detected the endogenous HlOr in the haller's organ of an adult tick. Furthermore, the new candidate gene associated with olfaction was identified by the next generation sequencing approaches.
