Abstract:   The antennal morphology and sensilla of Corythucha ciliata ( Say ) were studied using scanning electron
microscopy. The results show that the clavate antenna of both adult males and females consisted ofscape,pedicel and two  flagellomeres. Four types of sensillumwereobservedontheantennaofadultmalesandfemales,including the first  observation of sensillum gemmiformia in a heteropteran insect.Theseweresensillachaetica,sensilla basiconca,sensilla  trichodea and sensilla gemmiformia. No sexual dimorphism in adult sensilla was apparent. The sensilla chaetica could be   divided into big and small types. Females had significantly more sensilla than males. The quantity and distribution of eachkind of sensillum differed indifferent segments of the antenna.
