The gustatory sense organs in the mouthparts of th adult Green Leafhopper (Cicadella viridis L.) were observed by scanning electron microscope. The gustatory sensilla were composed of ten D-sensilla on the precibarim, eight P-sensilla on the wall of both side of eipharyngeal basin, and two H-sensilla in the food canal of the hypopharynx. D- and P-sensilla were again subdivided into 2 subtypes as two types by their morphology. Beneath the cuticle of epipharynx, two paris of nerve bundles were seen originating from D- and P-sensilla, respectively. And a pair of nerve bundles from H-sensilla, beneath the cuticle of hypoharynx, was observed.
