“…Both compounds are behavioural synergists when added in small amounts with codlemone, whereas larger amounts produce an antagonistic effect on male upwind flights . They are also the main pheromone components of several closely related species (Witzgall et al, 1996). Pheromone-sensitive PNs innervated the cumulus and five closely associated glomeruli, suggesting that these glomeruli are part of an MGC, analogous to that found in other moths (Christensen and Hildebrand, 1987;Christensen et al, 1991;Hansson et al, 1991;Karpati et al, 2008).…”

“…luedersiana belongs to the large Lepidopteran family Tortricidae (leaf-rollers), with over 5000 described species worldwide (Scoble, 1995). Much attention has been paid to the pheromone compositions of the species in the tribe Grapholitini, because it includes many serious pest species (Witzgall et al, 1996). P. luedersiana belongs to that species-rich group.…”

Abstract. Insect genital characters are extensively used in species level taxonomy, and their value in species delimitation is great. Based on the lock-and-key hypothesis and that genital differences function as a mechanical isolation system between species, the value of genital characters has been thought to be superior to non-genital characters. Although geographical and other kind of intraspecific variation of genitalia is often assumed very moderate, its real extent is insufficiently investigated. We examined patterns of morphological variation in the male genitalia of the tortricid moth Pammene luedersiana, using geometric morphometric tools including thin-plate spline deformation grids, and found significant variation. This variation is continuous both within and between populations. No systematic shape variation was observed between populations, but genital size showed some geographic variability. The results suggest that genital morphology is not constant and should therefore be used with caution in lepidopteran taxonomy.

“…CpomOR3 belongs to the conserved clade of lepidopteran pheromone receptors (Figure 1), although it binds to pear ester only and to none of the pheromonal compounds produced by C. pomonella females or closely related Cydia species (Witzgall et al, 1996(Witzgall et al, , 2001). CpomOR3 was almost equally sensitive when expressed in trichoid T1 and basiconic ab3 sensilla, except at the highest dose of pear ester (Figure 4).…”

Plant volatiles mediate host discrimination and host finding in phytophagous insects. Understanding how insects recognize these signals is a current challenge in chemical ecology research. Pear ester, ethyl (E,Z )-2,4-decadienoate, is a powerful, bisexual attractant of codling moth Cydia pomonella (Lepidoptera, Tortricidae) and strongly synergizes the male response to female-produced sex pheromone. We show here that the codling moth odorant receptor (OR) CpomOR3 is dedicated to detecting this plant volatile. Heterologous expression of CpomOR3 in Drosophila T1 trichoid and ab3A basiconic sensilla, followed by a screening with codling moth pheromone compounds and known plant volatile attractants, confirms that CpomOR3 binds to pear ester. Although CpomOR3 does not respond to any of the pheromone components tested, a phylogenetic analysis of lepidopteran chemosensory receptor genes reveals a close relationship of CpomOR3 with pheromone receptors (PRs) in moths. This corroborates the interaction of ecological and social chemosensory cues during premating communication. The finding that a plant volatile compound, pear ester, is a specific ligand for a PR-like lepidopteran receptor adds to our understanding of insect-plant interactions and emphasizes the interaction of natural and sexual selection during the phylogenetic divergence of insect herbivores.
