Chemosensory control of pollen ingestion in the hoverfly Eristalis tenax by labellar taste hairs


The labellar gustatory system of the dronefly Eristalis tenax L. (Syrphidae; Diptera) that enables the fly to discriminate between pollen and nectar is investigated, and the triggering of pollen ingestion is examined.
