[en] The ultrastructure of sensilla on the antennae and mouthparts of adult Sitophilus oryzae L. and S. granarius L. (Coleoptera: Curculionidae) were examined using scanning electron microscopy. Two types of sensilla trichoidea (ST1 and ST2), two types of sensilla basiconica (SB1 and SB2) and one type of sensilla chaetica (SC) were observed on the antennae of the two weevils species. Mouthparts in both species have two sub-types of sensilla basiconica (SB1 and SB2) and one type of sensilla chaetica (SC).
