The sex pheromone of the spruce seed moth, Cydia strobilella (L.) (Lepidoptera: Tortricidae), has not yet been identified, but several chemicals were found to be attractive to males (reviewed by Grant et al. 1989). E8-Dodecenyl acetate (E8-12:OAc) at 0.3-3.0 μg doses was the only effective attractant for males in field experiments in British Columbia, Ontario, and Newfoundland (Grant et al. 1989). Our objectives were to (i) confirm that female C. strobilella produce E8-12:OAc as a pheromone component, (ii) determine whether females produce additional pheromone components, and (iii) investigate the die1 periodicity of pheromonal communication.

Abstract(E)-11,13-Tetradecadienal (E11,13-14:Ald) is the major component of the sex pheromone of the western blackheaded budworm (WBB), Acleris gloverana Walsingham. The compound was identified in extracts of the female’s pheromone gland by coupled gas chromatographic - electroantennographic detection (GC-EAD) and coupled GC - mass spectrometry in selected ion monitoring mode. In field experiments, E11,13-14:Ald by itself was attractive, but addition of (Z)-11,13-tetradecadienal doubled trap catches of male WBB. (E)-11,13-Tetradecadienol or (E)-11,13-tetradecadienyl acetate in binary or ternary combination with E11,13-14:Ald did not enhance attractiveness of the bait. In comparative assessments of five different trap designs, Uni-traps appeared to be the most suitable for use in pheromone-based monitoring of populations of WBB.

AbstractZ8-tetradecenyl acetate (Z8-14OAc andZ8-tetradecenyl alcohol (Z8-14OH) were identified as sex pheromone components of the eyespotted bud moth, Spilonota ocellana (Denis and Schiffermüller) (Lepidoptera: Olethreutidae). Compounds were identified by gas chrornatographic-eleclroantennographic (GC-EAD) and GC-mass spectroscopic analyses and field tested in apple orchards in the Okanagan Valley, B.C. Although Z8-14OAc alone was attractive to male S. ocellana, the addition of 1–5% Z8-14OH strongly synergized its attraction. Field tests comparing the attractiveness of virgin female S. ocellana with various doses of a 99:1 blend of Z8-14OAc and Z8-14OH indicated the natural sex pheromone has only two significant components. A 99:1 blend of Z8-14OAC and Z8-14OH is suggested for monitoring and control of S. ocellana populations in British Columbia.

AbstractRaspberry crown borer, Pennisetia marginata (Harris) (Lepidoptera: Sesiidae), is a native North American species and pest of many cane fruits. Using coupled gas chromatographic–electroantennographic detection analyses (GC-EAD) we identified candidate sex pheromone components in pheromone gland extracts and effluvia from calling females. Analysis of gland extracts on a Zebron-5 column revealed four components (A, B, C, and D) that elicited strong responses from male antennae. The two most EAD-active components A and B were hypothesised to be (3E,13Z)-octadecadienal [(3E,13Z)-18:Ald] and (3E,13Z)-octadecadienol [(3E,13Z)-18:OH], respectively. Their retention times on other GC columns matched those of authentic standards, thus supporting structural assignments. Synthetic (3E,13Z)-18:Ald, and its GC rearrangement product (2E,13Z)-octadecadienal [(2E,13Z)-18:Ald; component C], also induced antennal responses in GC-EAD analyses of female effluvia. Compounds D in pheromone gland extract, and E and F in female effluvia, elicited EAD responses but could not be identified. In field trapping experiments, (3E,13Z)-18:Ald was the only component that attracted male P. marginata when tested alone. Attractiveness of (3E,13Z)-18:Ald was reduced when combined in binary or ternary blends with any of the other identified components, suggesting one or all may act as pheromone antagonists. In Aldergrove, British Columbia, Canada, peak diel attraction of male P. marginata to (3E,13Z)-18:Ald occurred between 16:00 and 18:00 hours Pacific Daylight Time, at temperatures of 21–23°C, on 30 August 2010, 3 September 2010, and 13 September 2010. We conclude that (3E,13Z)-18:Ald is the major pheromone component of P. marginata.

AbstractTwo species in the genus Monochamus Dejean (Coleoptera: Cerambycidae: Lamiinae) have recently been shown to have the same male-produced sex pheromone, 2-undecyloxy-1-ethanol (monochamol), suggesting that other congeners may share the same pheromone. We tested that hypothesis by conducting field bioassays of monochamol, in combination with bark-beetle pheromones and the host plant volatiles ethanol and α-pinene, in southern British Columbia, Canada. We captured 603 Monochamus clamator (LeConte), 63 Monochamus obtusus Casey, 245 Monochamus scutellatus (Say) (tribe Monochamini), and 42 Acanthocinus princeps (Walker) (tribe Acanthocinini). All three Monochamus species were significantly attracted to the combination of monochamol and host plant volatiles, whereas bark-beetle pheromones plus plant volatiles and plant volatiles alone were minimally attractive. Adding bark-beetle pheromones to the monochamol plus plant volatiles treatment synergised attraction of M. clamator, but not the other two Monochamus species. Acanthocinus princeps was most strongly attracted to the combination of bark-beetle pheromones and plant volatiles, and did not appear to be affected by the presence or absence of monochamol in baits. We conclude that monochamol is a likely pheromone component for the three Monochamus species, and that monochamol plus host plant volatiles is an effective attractant for these and perhaps other North American Monochamus species.

AbstractThe sex pheromone of the peach twig borer, Anarsia lineatella (Zeller), was identified 30 years ago but the communication biology of this species has hardly been studied. In laboratory experiments, female moths kept at a photoperiod of 16L:8D (20 ± 2 °C, 70% ± 5% relative humidity) emitted pheromone before, during, and after sunrise (0400–0600 Pacific standard time), whereas pheromone was present in pheromone glands at similar quantities throughout the 24 h recording period. These data suggest that pheromone production and emission are not closely linked. In field experiments during July 2001 near Livingston, California (CA), and during June 2002 near Keremeos, British Columbia (BC), males were attracted to traps baited with synthetic sex pheromone (CA) or conspecific females (BC) only between 0300 and 0600 (Pacific standard time), suggesting overlap between periods of pheromone emission by females and attraction response by males. Groups of females in the presence of conspecific males, which were physically separated from females, emitted less sex pheromone than groups of females in the absence of males, suggesting that males communicate their presence to females and females change their behaviour in response.

AbstractThe apple clearwing moth, Synanthedon myopaeformis (Borkhausen) (Lepidoptera: Sesiidae), is a European species discovered in Cawston, British Columbia, Canada, in 2005. Using coupled gas chromatographic – electroantennographic detection analyses we identified candidate sex pheromone components in pheromone gland extracts and effluvia from calling females. Analysis of gland extracts using four gas-chromatography (GC) columns (DB-5, DB-17, DB-23, and DB-210) showed three components (A, B, and C) that consistently elicited strong responses from male antennae. Based on previous work, the most antennally stimulatory component, B, was hypothesized to be (3Z,13Z)-octadecadienyl acetate ((3Z,13Z)-18:OAc). Its retention time on the four GC columns and its mass spectrum in a concentrated extract matched those of an authentic standard, thus confirming structural assignment. Components A and C were below the detection threshold of the mass spectrometer, but their retention times on the four GC columns matched those of authentic standards of (3Z,13Z)-octadecadienol ((3Z,13Z)-18:OH) and (2E,13Z)-octadecadienyl acetate ((2E,13Z)-18:OAc), respectively. Synthetic (3Z,13Z)-18:OAc, (3Z,13Z)-18:OH, and (2E,13Z)-18:OAc all elicited strong responses from male antennae, further supporting structural assignments of these three components. Of these antennally active compounds, only (3Z,13Z)-18:OAc and (3Z,13Z)-18:OH were detected in effluvia from calling female moths. In field trapping tests in Cawston, (3Z,13Z)-18:OAc alone was as attractive as, or more attractive than, binary or ternary blends containing this component. (2E,13Z)-18:OAc was behaviourally inactive alone or in combination with (3Z,13Z)-18:OAc, whereas 5% (3Z,13Z)-18:OH appeared antagonistic. Our analysis confirms that (3Z,13Z)-18:OAc is the major pheromone component in S. myopaeformis, and it alone is sufficiently attractive for use in detection surveys and development of pheromone-based controls for this introduced pest in Canada.

AbstractMoths of the genus Pseudexentera are early-season fliers that include three species of economic importance: P. spoliana (Clemens) on oak (Quercus), P. oregonana (Walsingham) on aspen (Populus), and P. mali Freeman on apple (Malus). GC and GC/MS analysis, EAG and behavioral bioassays, and field tests confirmed that Z10-16:Ac is an attractive sex pheromone component of female P. spoliana. Capillary GC analysis supported by GC/MS also indicated the presence of 16:Ac, Z10-16:OH, and 16:OH in pheromone extracts and there was tentative GC evidence for Z12-16:Ac. However, addition of these compounds to Z10-16:Ac in various blends did not enhance male attraction. The major sex pheromone component of female P. oregonana is Z8-14:Ac. There was also GC and GC/MS evidence for Z8-14:OH and tentative GC evidence for 14:Ac in the pheromone of this species. Their addition to Z8-14:Ac failed to increase moth catches in baited traps. Pseudexentera mali males were attracted by Z,Z-8,10-16:Ac, a previously reported sex pheromone of this species. Pheromone lures targeted for each species were not cross-attractive.
