An odorant-binding protein of Asian citrus psyllid, Diaphorina citri, participates in the response of host plant volatiles.

These results show that DcitOBP7 plays an important role in the olfactory response. This finding may provide new insight into the functions of OBP families in D. citri and aid in the development of safe strategies for managing D. citri populations. © 2021 Society of Chemical Industry.
