Antennal morphology of the soybean stemborer Dectes texanus texanus LeConte (Coleoptera: Cerambycidae)
Journal of the Kansas Entomological Society 76 (3), 397-405
Abstract: The antennal receptors of the soybean stemborer, Dectes texanus texanus LeConte, were examined with a scanning electron microscope. Male and female antennae have nine segments, and have a dense covering of sensilla chaetica. Structurally, there are three types of sensilla chaetica: I, II and III. Types I and II protect the underlying sensilla basiconica located on the distal eight segments, while type III appears to limit antennal movement at the junctions of flagellomeres. Blunt, curved basiconic pegs are found on both sexes and are the main olfactory sensilla. Morphologically distinct contact chemosensilla are also located on the tips of male and female antennae. The putative function of these sensilla is discussed.
