Candidate Chemosensory Genes Identified in the Adult Antennae of and Binding Property of Odorant-Binding Protein 15.

Chemosensory genes play important roles in insect behaviors and have thus become potential molecular targets for pest control based on the manipulation of chemoreception-driven behaviors. The great gray weevil (Chevrolat) (Coleoptera: Curculionidae) is an important agricultural pest that causes serious economic losses to many crops in China, but its chemosensory genes have not been reported. Here we assembled the antennal transcriptomes of female and male adult and revealed the major chemosensory genes necessary for olfaction.
