Functional Characterization of Two Antenna-Enriched Odorant-Binding Proteins From Bactrocera minax (Diptera: Tephritidae).

Olfaction is of great significance for insect mate-seeking and host-locating behaviors. Insect odorant-binding proteins (OBPs), especially those antenna-enriched OBPs, are thought to discriminate, capture and transport odorant molecules to olfactory receptors, but this has not been fully clarified in Bactrocera minax (Enderlein), an economically important pest of citrus crops. Our previous studies showed that seven OBP genes (BminOBP1-7) were identified from B.
