The grape weevil, Naupactus xanthographus Germar (Coleoptera: Curculionidae), is a polyphagous insect native to southern South America that causes considerable damage in grape and other fruit species. In this study, the morphology and ultrastructure of the antennae and the antennal sensilla of N. xanthographus were investigated using scanning electron microscopy and transmission electron microscopy. The antennae consist of a scape, a pedicel, a funicle, and a zone called the "club," which are all formed by a total of 12 antennomers. Different types of sensilla were observed: sensilla trichoidea, sensilla chaetica type 1 and 2, sensilla basiconica, and sensilla rod-like. No sexual dimorphism was observed. The possible functions of the sensilla are discussed in relation to their morphology and ultrastructure.
葡萄象甲,Naupactus xanthographus Germar(鞘翅目:象甲科),是一种原产于南美洲南部的多食性昆虫,对葡萄和其他水果品种造成相当大的损害。在本研究中,利用扫描电子显微镜和透射电子显微镜研究了葡萄象甲触角及其感觉器的形态和超微结构。触角由柄节、梗节、鞭节和一个称为“棒”的区域组成,它们均由总共12节触角节构成。观察到了不同类型的感觉器:毛形感觉器、1型和2型刺形感觉器、锥形感觉器和棒状感觉器。未观察到两性异形。根据感觉器的形态和超微结构对其可能的功能进行了讨论。
