中文摘要： 利用扫描电镜对悬铃木方翅网蝽Corythucha ciliata ( Say)雌、雄成虫触角背面和腹面进行观察。结果表明:悬铃木方翅网蝽触角为棒状，共4 节，分为柄节、梗节和鞭节。触角上共有4 种感器，分别为刺型感器、锥形感器、毛型感器和芽型感器;这些感器不存在性二型现象。其中，刺型感器分为大刺型感器和小刺型感器2 种类型;芽型感器首次在异翅亚目昆虫触角上发现。雄成虫触角感器数量明显多于雌成虫，不同类型的感器在触角各节上的数量与分布各不相同。
英文摘要： 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．
