“…The tarsus is prolonged by the pretarsus, which bears two simple claws (C), a median arolium (A), and two lateral pulvilli (P) covered by cuticular ornamental ‘microtrichia’ (Figure 1a). Two types of sensilla chaetica could be recognized on the basis of the description made by Cuperus (1985) and Faucheux (1999): sensilla chaetica type I, having a stout hair‐shaft inserted into a cuticular articulating socket and a blunt tip with a terminal pore; and sensilla chaetica type II, with a sharp ending aporous hair‐shaft inserted into a tighter socket.…”

“…Six sensilla chaetica type I evenly ring the tip of the terminal antennal segment, whereas ventral half‐rings are present on the proximal segments (Figure 7b). Comparable sensilla are distributed on the antennal segments of C. fumiferana , E. kuehniella , and H. nebulella (Albert & Seabrook, 1973; Anderson & Hallberg, 1990; Faucheux, 1991), and have been shown by staining and tip‐recording techniques to have a bimodal contact chemo‐mechanosensory function (Cuperus, 1985; Faucheux, 1991). In P. xylostella , Justus & Mitchell (1996) suggested that such uniporous sensilla could be used to taste an oviposition substrate through antennation movements.…”

We describe the number, distribution, and function of sensilla located on different organs of Lobesia botrana (Lepidoptera: Tortricidae) females using scanning electron microscopy, selective staining, and contact electrophysiology. The tarsi of the prothoracic legs bear contact chemo-mechanoreceptor sensilla chaetica (5 -13 per tarsomere), arranged in rings mainly concentrated on ventral surfaces, and different mechanosensory structures (sensilla chaetica, sensilla squamiformia, sensilla campaniformia, and spines). A single contact chemo-mechanoreceptor sensillum chaeticum is present between the claws on the pretarsus. The ventral surface of the ovipositor lobes is covered with numerous mechanosensory sensilla chaetica of different types, out of which 10 have a contact chemosensory function. Putative contact chemo-mechanoreceptor sensilla were also observed on the proboscis and antenna. Longitudinal rows of alternated sensilla styloconica and basiconica are present on the distal part of the proboscis, and rings of sensilla chaetica are present at the antennal tip. The sensilla on these body parts may play different roles in the selection of an oviposition site.

“…Shields and Hildebrand (2001) investigated that the styliform complex sensillum at the antennae of female M. sexta is single-walled, aporous, and resembles a peg. A similar styloconic sensilla has been described in several insects, such as ermine moths (Cuperus, 1985), silkmoths (Steinbrecht et al, 1989), turnip moths (Hallberg, 1981), European cornborers (Hallberg et al, 1994), and male M. sexta (Lee and Strausfeld, 1990).…”

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.

“…All species exhibit sexual dimorphism for these two characteristics, Y. vigintipunctatus excepted (19). The ultrastructure of the sensilla trichodea, sensilla basiconica, and sensilla coeloconica, the so-called wall-pore sensilla, indicates that they might be involved in chemoreception (3,20).…”
