　　論文摘要：The ultrastructural morphology of the antennae and mouthparts of Dentatissus damnosa (Chou & Lu) (Hemiptera: Issidae) was examined using scanning electron microscopy. Eight types of sensilla were found on antennal segments, including a B?hm bristle on the scape, sensillum trichoideum and plaque organ on the pedicel, sensillum chaeticum and two subtypes of sensilla campaniformia on these two segments; Bourgoin’s organ and sensillum basiconicum were observed on the basal bulb of the flagellum. The mouthparts of D. damnosa conform to the typical piercing-sucking type in Hemiptera. The mandible styles bear 7 protuberances on the distal extremity, including sensilla chaetica, sensilla basiconica and a pair of sub-apical labial sensilla at different positions on the labium. The labial tip forms three sensory fields and each dorsal sensory field consists of 9 uniporous peg-like sensilla, 1 multiporous peg-like sensillum and 7 long sensilla basiconica. The ventral sensory field has two dome-shaped sensilla and two pairs of different sensilla basiconica.
