Abstract

Ulomoides dermestoides (Chevrolat) (Coleoptera, Tenebrionidae) is a storage pest and an insect of medical importance. Since this insect lives in the dark and does not emit sounds, its sensation of the external environment is based primarily on sensilla, so it could serve as an ideal model for the study of these structures. Scanning electron microscopy was used to identify the types of antennal sensilla of male and female U. dermestoides and to characterize the function of different types of sensilla observed. The bead-like antenna of U. dermestoides is composed of a scape (one segment), a pedicel (one segment), and a flagellum (nine segments). Six types of sensilla were observed on the antennae of both females and males: the sensilla trichoidea (subtypes I, II, and III), sensilla chaetica (subtypes I, II, and III), sensilla basiconica, basiconic mastoid sensillum, sensilla styloconica (subtypes I and II), and the Böhm bristle. The Student's t test was used to compare the distribution of these sensilla.
