“…The latter observation also suggests the presence of a ∆11-desaturase, which is the key enzyme involved in the biosynthesis of sex pheromones in many lepidopterous insects (Bjostad et al 1987), only in the dorsal part of the intersegmental membrane. Thus, morphological and biochemical observations in the present study strongly indicate that the sex pheromone gland of female O. nubilalis is not a ring gland as previous shown (Hammad 1961), but rather a dorsal scent fold (Götz 1951).…”

“…Sex pheromone glands of female Lepidoptera are commonly found as modified intersegmental membranes between the 8th and 9th abdominal segments (Götz 1951;Percy-Cunningham and MacDonald 1987). They also occur between abdominal segments 7 and 8 in Sesamia nonagrioides (Noctuidae) (Sreng and Sreng 1988), around the ostium bursae in Plutella xylostella (Plutellidae) (Chow et al 1976), and at the papillae anales in Heliothis virescens Fabricius (Teal et al 1983).…”

The sex pheromone gland of the female European corn borer moth, Ostrinia nubilalis was studied using light and electron microscopy. The pheromone gland is formed by hypertrophied epidermal cells at the mid-dorsal region of the intersegmental membrane between abdominal segments 8 and 9/10. Active glandular cells contain extensive apical membrane foldings, a single nucleus, many free ribosomes, numerous mitochondria, microtubules and lipid droplets. Smooth endoplasmic reticulum is scanty. In young moths, the glandular cells are smaller in size, the microvilli at the apical membrane are poorly developed and the cytoplasm contains fewer mitochondria, microtubules, and no lipid droplets. The surrounding unmodified epidermal cells are small cuboidal or squamous cells. These cells have ill-defined apical membrane foldings and do not contain lipid droplets in the cytoplasm and the overlying cuticle. Fatty acids analyses revealed the presence of the sex pheromone components, (E)-11-tetradecenyl acetate, and their immediate precursors, methyl (E)-11- and methyl (Z)-11-tetradecenoate, only in the dorsal portion of the cylindrical intersegmental membrane. Results of the present study show that the sex pheromone gland of O. nubilalis is restricted to the dorsal aspect of the intersegmental membrane between segments 8-9/10 and is not a ring-gland.

“…Glands of female Lepidoptera are most commonly found as modifications of the intersegmental membrane between the 8 th and 9 th abdominal segments41, which is a location mostly consistent with that in other orders42; however, the exact location of where the membrane becomes glandular is extremely variable among female lepidopterans42. According to the description of the sex pheromone gland of other gelechiid moth P. gossypiella 16 and Phthorimaca operculella 43, we speculated that the eversible sac situated dorsally in the 8 th –9 th intersegmental membrane of S. cerealella was the sex pheromone gland of female moth.…”

The Angoumois grain moth, Sitotroga cerealella, is a serious pest of stored grains worldwide. Presently, the best effective control against the moth is to disrupt the sexual communication between sexes. Sexual communication in moths includes two processes in which females produce and release pheromones from the sex pheromone gland and males detect and respond to them with a relatively sophisticated olfactory system in their antennae. To better understand these processes, we studied the ultrastructure of antennal and ovipositor sensilla of S. cerealella and determined the location of the female sex pheromone gland. Seven types of antennal sensilla were identified on both sexes: sensilla trichodea, sensilla chaetica, sensilla coeloconica, sensilla styloconica, sensilla auricillica, sensilla squamiformia and Bӧhm bristles. Of these sensilla, the sensilla trichodea were significantly more abundant on male antennae than on those of females, suggesting that these sensilla may detect the sex pheromones. On the ovipositor, only sensilla chaetica of various lengths were found. The sexual gland was an eversible sac of glandular epithelium that was situated dorsally in the intersegmental membrane between the 8th and 9th abdominal segments. These results will lead to a better understanding of mate finding with sex pheromones for this worldwide pest species.

FEMALE SEX PHEROMONE IN KORSCHELTELLUS GRACILIS (GROTE) (LEPIDOPTERA: HEPIALIDAE)

The Canadian Entomologist 126: 31-41 (1994) In laboratory wind tunnel studies, quiescent Korscheltellus gracilis (Grote) females initiated wing fanning as light intensity was reduced to 25-1 1 lx at the end of a 16-h, 450-lx photophase. Males downwind of a wing-fanning female initiated wing fanning, rapid walking, or both, and upwind flight toward the female typically ensued shortly thereafter. Wing-fanning females whose abdomens had been removed, and excised hind wings of females evoked the same male responses, but females whose hind wings had been removed evoked no male response. The sex pheromone of K. gracilis evidently is released from the female's hind wings, a so far unique site of pheromone release in female Lepidoptera. The importance of this finding to understanding the mating system of hepialids and the ancestral form of pheromone release among the Lepidoptera is considered. Kuenen, L.P.S., D.L. Wagner, W.E.
