“…The cuticular lipids could originate from the vesicles or droplets of variable electron-density which are present in the proximal part of the outer sensillum-lymph cavity. Comparable inclusions have also been reported from several insects such as Bombyx (Hunger and Steinbrecht, 1998), Periplaneta (Altner et al, 1977), Aedes (McIver, 1974), Drosophila (Shanbhag et al, 1999), Psylliodes (Bartlet et al, 1999), or Carausius (Monteforti et al, 2002). They appear to be released by the trichogen and tormogen cells into the outer sensillum-lymph cavity.…”

Ultrastructural examination of grooved-peg (GP) sensilla on the antenna of fifth instar Triatoma infestans nymphs by scanning electron microscopy and transmission electron microscopy reveal that they are 8-18 mm long with a diameter of about 2 -2.8 mm at the nonarticulated base. Some pegs have a terminal pore. These double-walled wall-pore (dw-wp) sensilla have an outer cuticular wall with 13 -18 longitudinal grooves at the distal part of the peg. Groove channels are present at the bottom of the grooves from which radial spoke channels lead into the inner sensillum-lymph cavity. A dendrite sheath connects the tip of the thecogen cell to the inner cuticular wall thus forming separated outer and inner sensillum-lymph cavities. Four or five bipolar receptor cells are ensheathed successively within the GP sensilla by the thecogen cell, trichogen and tormogen cells. The inner dendritic segments of each sensory cell give rise at the ciliary constriction to an unbranched outer dendritic segment which can reach the tip of the sensillum.Electrophysiological recordings from the GP sensilla indicate that they house NH 3 , short-chain carboxylic acid and short-chain aliphatic amine receptor cells and can be divided into three functional sub-types (GP 1 -3). All GP sensilla carry a receptor cell excited by aliphatic amines, such as isobutylamine, a compound associated with vertebrate odour. GP type 1 and 2 sensilla house, in addition, an NH 3 -excited cell whereas the type 2 sensilla also contains a short-chain carboxylic acid receptor. No cell particularly sensitive to either NH 3 or carboxylic acids was found in the grooved-peg type 3 sensilla. GP types 1, 2 and 3 represent ca. 36, 10 and 43% of the GP sensilla, respectively, whereas the remaining 11% contain receptor cells that manifest normal spontaneous activity but do not respond to any of the afore mentioned stimuli.

“…Sensilla chaetica are prevalent in Coleoptera (Angst and Lanier, 1979;Bartlet et al, 1999;Chen et al, 2010;Dyer and Seabrook, 1975;Harbach and Larsen, 1977;Ren et al, 2012). The sensilla chaetica covering both the entire antenna and the posterior abdomen of C. caragana are typical mechanosensitive sensilla (Schneider, 1964).…”

“…Studies of sensillar morphology and ultrastructure in Coleoptera have involved insects in the families Curculionidae, Chrysomelidae, Buprestidae, and Scarabaeidae. Little research has been focused on the family Cerambycidae (Bartlet et al, 1999;Chamorro et al, 2012;Crook et al, 2008;Dai and Honda, 1990;Dyer and Seabrook, 1975;Farazmand and Chaika, 2012;Jourdan et al, 1995;Kim and Yamasaki, 1996;Lopes et al, 2002;Liu et al, 2012;Merivee et al, 1999Merivee et al, , 2000Merivee et al, , 2010RomeroLópez et al, 2013;Saïd et al, 2003;Srivastava, 2003). Only a few authors have studied sensilla on insect ovipositors.…”

“…An emphasis was placed on the structures and abundance of antennal sensilla, because sexual dimorphism in antennal morphology is common among this group of insects. Although some information is available for other families of beetles (Daly and Ryan, 1979;Baker and Monroe, 1995;Yamasaki, 1996, 1998a, b;Bartlet et al, 1999;Merivee et al, 1999;Baker, 2001a, b), relatively few studies have been carried out on the sensillum structure of scarab beetles, with exceptions (Agren, 1985;Leal and Mochizuki, 1993). The main purpose of this paper is to describe the sexual dimorphism in body dimension and antennal sensilla in this grub beetle.…”

The white grub beetle, Dasylepida ishigakiensis shows sex dimorphism in body dimensions and abundance of antennal sensilla. Body length was almost identical in the two sexes, but the abdomen was significantly longer in females than in males. Males had longer legs than females. Six types of sensilla were observed on antennal terminal lobes. The total number of sensilla on the inner surface of terminal antennal lobes was larger in males than in females. One type of sensilla showed a sex-specific size difference. Among individuals that were collected as third stadium larvae on Miyako Island, Okinawa, Japan and reared in the laboratory (nϭ527), three emerged as adults with asymmetrical antennae. One was found to represent a gynandromorph and the others were a male and a female with a deformed antenna.
