“…The main olfactory appendage responsible for the detection of such chemical signals are the antennae. Our morphological analyses verified that the antennae of T. licus are similar to the antennae of other moths in Castniidae and Sesiidae [12,13,[30][31][32][33], as well as to those of butterflies in Hesperiidae and Papilionidae [34,35]. The external features of the antennae are believed to have two functions: provide a protective barrier for the sensilla [36], and to trap odorant molecules [37].…”

The giant sugarcane borer Telchin licus (Drury, 1773) (Lepidoptera: Castniidae) is a day-flying moth pest of sugarcane, pineapples and bananas. To better understand the chemical communication in this species, we examined the morphology of its olfactory system and the chemical composition of its body parts. The ventral surface of the clubbed antennae of T. licus has six morphological types of sensilla: sensilla trichodea, basiconica, chaetica, squamiforma, coeloconica, and auricillica. The telescopic ovipositor shows no evidence of a sexual gland, or female-specific compounds. On the other hand, the midleg basitarsus of males releases (E,Z)-2,13-octadecadienol and (Z,E)-2,13-octadecadienol, which are electroantennographically active in both sexes. These compounds are known female sex pheromones in the Sesiidae family and are male-specific compounds in another castniid moth, although further investigations are necessary to elucidate their ecological role in the Castniidae family.

“…For example, three subtypes of sensilla trichodea were found on Synanthedon scitula and Ostrinia nubilalis (Hu¨bner) (Frank et al, 2010;Hallberg et al, 1994). However, Xiangqun et al (2014) found only one type of sensilla trichodea at the antennae of Parnara and Pelopidas species (Lepidoptera, Hesperiidae).…”

“…The sensilla squamiformia of female S. littoralis are similar in shape and distribution to those reported in different moth species, S. scitula (Harris), Coleophora sp. and Z. dixolophella Dyar (Gomez et al, 2003;Frank et al, 2010;Faucheux, 2011) and different from Coleoptera (Gao et al, 2013;Xiangqun et al, 2014).…”

Female cotton leaf worm Spodoptera littoralis (Biosduval) is highly dependent on its antennal sensory structures for host location for feeding or oviposition. The external structure, number, and distribution of the antennal sensilla of female S. littoralis were examined with light and scanning electron microscopy. The antenna of adult female is filiform, composed of a scape, a pedicel and a flagellum. The flagellum has 65-80 segments densely packed with sensilla distributed on the ventral surface and lateral edges of the flagellum except the dorsal surface which is packed with scales. Eight types of sensilla; trichodea, basiconica, auricillica, coeloconica, uniporous peg, chaetica, styloconica, and squamiformia were detected. Total number of antennal sensilla varied among different antennal portions. Proximal segments showed significantly more short trichoid and basiconic sensilla than distal ones, while distal segments have the longest sensilla chaetica. Last antennal segment carries the higher number of sensilla chaetica than other segments and ends with an apical crown which has 1-3 branches, each is endowed with 4-6 apical aporous sensilla styloconica. The possible function of the antennal sensilla is discussed in relation to their morphology. ª 2015 The Egyptian German Society for Zoology. Production and hosting by Elsevier B.V.

“…A summary of the sensilla types found on the antennae of different species of Lepidoptera follows. For Synanthedon scitula , the antennae have sensilla auricillica, basiconica, chaetica, coeloconica, squamiformia, styloconica, and trichodea (three subtypes) (Frank, Leskey, & Bergh, ). For Talponia batesi , sensilla trichodea, chaetica, styloconica, coeloconica, and auricillica are found on the antennae (Gomez & Carrasco, ).…”

Eogystia hippophaecolus (Hua et al.) is an important boring pest that primarily damages sea buckthorn, causing large ecological and economic damages in China. In this study, we used scanning electron microscopy to investigate the sensilla on six olfactory tissues of male E. hippophaecolus: antennae, labial palps, external genitals, propodeum, mesopodium, and metapedes. On the antennae, two types of sensillum trichodea, two types of sensillum basiconica, a type of sensillum coeloconica, and Böhm's bristles were found. The labial palps had sensilla trichodea and chaetica. On the external genitals, three types of sensilla trichodea were the only sensilla. Böhm bristles were found on the base of the tibia and at the terminus of the tarsus. Most sensilla were distributed on the tarsus of the three pairs of legs, and notably, a majority of which were sensilla trichodea and sensilla chaetica, were on the pretarsus and telotarsus of the three pairs of legs. In this study, the distribution, number, type, and morphology of the sensilla on six olfactory organs of E. hippophaecolus were determined, which established the foundation for a future immunohistochemical search of olfactory proteins. Research highlights Eogystia hippophaecolus is a serious pest of seabuckthorn. The distribution, number, type, and morphology of olfactory sensilla of E. hippophaecolus are determined. The function and distribution of sensilla are compared with those of other insects.
