Faucheux, Michel J. (2017). Antennal sensilla of the armoured ground cricket, Eugaster powysi Kirby, 1891 (Orthoptera, Tettigoniidae, Hetrodinae). Bulletin de l’Institut Scientifique, Rabat, Section Sciences de la Vie, 39: 1-17.
Sensilla on the antennae of the adult armoured ground cricket, Eugaster powysi, were studied using scanning electron microscopy to determine the sensilla morphology and their possible chemo- and mechanoreceptive functions for food detection. Twelve types or subtypes occur in males and thirteen in females: aporous sensilla chaetica (62.6 % of total sensilla in males, 63.5% in females) with a tactile mechanoreceptive function; uniporous sensilla chaetica of three subtypes (12.5-12.7%) with a contact chemoreceptive function; multiporous sensilla trichodea (5.6-7.9%); multiporous sensilla basiconica of three subtypes (13.1-13.9%); multiporous sensilla coeloconica (0.8-0.9%), all multiporous sensilla being olfactory receptors; aporous sensilla coeloconica (2.2%) and aporous sensilla coelocapitula (0.1% in female) with a possible thermo- hygroreceptive function; aporous Böhm sensilla (0.4-0.5%) and sensilla campaniformia (0.5-0.6%) which are proprioceptors. These results are related to the behaviour of Eugaster and compared with those obtained in other Orthoptera, Mantodea and Blattodea.
