“…For most of these putative muscle‐related gene representatives, homologues were found in the B. mori pheromone gland transcriptome as well (Table 3). Whether these gene representatives play a role in pheromone production, or are expressed in the well‐developed musculature attached to the terminal abdominal segments for the extrusion of the pheromone gland (White et al ., 1972; Gupta, 1979; Percy & George, 1979), remains elusive.…”

Moths generally rely on pheromone communication for mate finding. The pheromone components of most moths are produced by a common pathway of fatty-acid biosynthesis coupled with species-specific modifications of the final products. Some genes involved in moth pheromone production have previously been described, whereas others remain to be characterized and thus the molecular mechanisms accounting for the production of species-specific blends are far from understood. The turnip moth, Agrotis segetum, has a multicomponent pheromone, consisting of at least four components derived from palmitic and stearic acid. Different populations produce and respond to different pheromone blends, which makes this species an excellent model for research on genes and molecular mechanisms involved in moth pheromone production. For this purpose, we performed an expressed sequence tag (EST) analysis of two cDNA libraries, one representing the female pheromone gland and the other representing the remainder of the insect body. Among 2285 ESTs analysed altogether, we identified a unigene set of 707 putative gene representatives. The comparative distribution of those in the two libraries showed the transcriptomes of the tissues to be clearly different. One third of the gene representatives were exclusively found in the pheromone gland. From sequence homology to public database information we assigned putative functional roles for a majority of the unigenes and then compared functional profiles of the two tissues. In the set of ESTs more abundant in the pheromone gland library, we found homologues of an acyl-CoA Delta11-desaturase, a G-protein subunit, a chemosensory protein as well as a juvenile hormone binding protein.

“…Female sex pheromone glands among tortricids are dorsal invaginations between the 8th and 9th abdominal segments (Barnes, Peterson, & O'Connor, ; George, ; Roelofs & Feng, ). Full extrusion of the gland is usually associated with a slight raising of the tip of the abdomen from the substrate which can be blocked by the adhesive contacting the ventral surface of the terminal abdominal segments (Percy & George, ; Sanders, ). Females positioned on their sides rarely had “stuck” abdomens and were effective in capturing moths.…”

“…Actively calling female tortricids have a standard calling position that could be impacted by the adhesive. This includes raising the wings and dorso-flexion of the abdomen to expose their sex pheromone gland (Percy & George, 1979). Traps are typically checked weekly or biweekly in monitoring programmes, and there has not previously been any attention given to the longevity of moths on liners, except when traps have been used to monitor insecticide resistance (Knight, Brunner, & Alston, 1994).…”

Studies compared moth captures of three pests (Lepidoptera: Tortricidae) of apple, Malus domestica Borkhausen, in delta traps using removable liners coated with either a sticky gel (SG) or a hot‐melt pressure sensitive (HMPS) adhesive. Laboratory and field studies with Cydia pomonella (L.), Choristoneura rosaceana (Harris) and Grapholita molesta (Busck) demonstrated that traps with either liner, baited with a pair of virgin females catch males, but at significantly different levels. In the field, male moth captures in traps with the HMPS liner were significantly greater than in traps with the SG liner for C. rosaceana, and G. molesta; but not for C. pomonella. Similar results were observed in laboratory studies using flight tunnels. Additional studies demonstrated that this difference in moth captures between liners was not due to levels of female mortality, but instead was correlated with the occurrence of the female's ventral abdominal surface becoming stuck in the adhesive. Studies showed that a significantly greater proportion of females of all species had their ventral abdomen stuck in the SG than HPMS adhesive on day 1, but only G. molesta and C. rosaceana on day 3. In addition, the tackiness of the two adhesives affected moth movement on the liner with males and females of all species moving farther on liners with SG than HMPS adhesive. A greater proportion of female G. molesta and C. pomonella were either stuck supined or laterally on the SG than HMPS adhesive, and females in this position captured as many males as when prone and unstuck on the liner. Our studies demonstrate that adhesives can secondarily influence male moth captures on trap liners when used with bisexual attractants, and that adhesive type should be considered when developing action thresholds.
