摘　　要：利用扫描电镜观察了双斑长跗萤叶甲Monolepta hieroglyphica(Motschulsky)成虫触角及其感器的形态与分布。结果表明:双斑长跗萤叶甲成虫触角为线状,由柄节、梗节和鞭节组成,鞭节有9节,其中,雄虫的触角比雌虫长;感器类型有毛形感器(1型、2型和3型)、刺形感器、锥形感器(1型和2型)、腔锥形感器、Bhm氏鬃毛、钟形感器共9种。雌雄成虫触角感器类型无差异,但雄虫触角上的感器分布要比雌虫的稠密。Antennal morphology and sensilla on the antennae of Monolepta hieroglyphica（Motschulsky）, were observed using scanning electron microscopy. The results show that the linear antenna is comprised of a scape, pedicel and a nine- segmented flagellum. The antennae of males are longer than those of females. Nine different sensilla types were distinguished. There were three types of sensilla tfichodea, sensilla chaetica, two types of sensilla basiconica, sensilla coeloclnica, sensillla campaniformia, and Bcihm bristles. No differences in the types of sensilla were observed between female and male adults. The density of sensilla on the antennae of male adults was higher than in females.
