“…In addition to the sensillar structures, we observed cuticular pores on the surface of the club zone. Pores are also reported in other weevil species, such as Hypera meles (Smith et al, ), P. nitidus (Yan et al, ), E. chinensis and E. brandti (Yu et al, ), and Rhyssomatus nigerrimus (Delgado‐García et al, ). The function of these pores remains unclear; they may be openings of epicuticular glands, although a role in chemosensory processes has also been suggested (Yu et al, ).…”

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.
