Popis: The onion fly, Delia antiqua (Meigen), is a pest specialized to the onion, Allium cepa L., and some other Allium plants. Host odorants play an important role in the attraction of D. antiqua adults and stimulation of oviposition in females. Odorant-binding proteins (OBPs) may serve as a first step in the perception of these chemical cues. In this study, to identify all OBP genes expressed in the chemosensory tissues in D. antiqua, RNA-seq analysis was carried out. In addition to the seven OBP genes previously identified, we found eight novel OBPs. Comparisons with Drosophila melanogaster Meigen OBP genes revealed that these 15 D. antiqua OBPs cover the structural variety observed in D. melanogaster OBPs, including Plus C and Minus C OBPs. These results suggest that a relatively large repertoire of chemosensory genes is maintained even in a specialist feeder.
