AbstractField trapping trials showed that Cameraria gaultheriella Walsingham and C. lobatiella Opler and Davis (Lepidoptera: Gracillariidae) were attracted in significant numbers in British Columbia, Canada, to sticky traps baited with 10 µg of (E,Z)-8,10-tetradecadienal (E8Z10-14Ald), the sex pheromone of the European horse chestnut leafminer, C. ohridella Deschka and Dimic. There was perfect specificity in captures at habitats located only about 8 km apart from each other: C. gaultheriella was captured exclusively at a humid habitat covered by the shrub salal, Gaultheria shallon Pursh (Ericaceae), whereas C. lobatiella was trapped at an arid location with Garry oak trees, Quercus garryana Dougl. (Fagaceae). Seasonal flight patterns of these two Canadian Cameraria species, as monitored by pheromone traps, indicated differences in their respective flight periods. The possibility of additional cryptic components in the respective pheromones of these three Cameraria species attracted to E8Z10-14Ald is discussed.

Attraction of male Mayetiola thujae (Diptera: Cecidomyiidae) to the sex-pheromone blend of (2S,12S)-, (2S,13S)-, and (2S,14S)-diacetoxyheptadecane is reduced in the presence of the SR- or RR-stereoisomers

AbstractIn a field trapping experiment in an abandoned seed orchard of western red-cedar, Thuja plicata Donn × D. Don, in British Columbia, we show that attraction of male red-cedar cone midges, Mayetiola thujae (Hedlin), to the pheromone blend (2S,12S)-, (2S,13S)-, and (2S,14S)-diacetoxyheptadecane is reduced in the presence of a blend of all other stereoisomers, or of the three SR- or RR-stereoisomers. The three RS-stereoisomers, in contrast, had no significant effect. Thus, synthetic pheromone for monitoring M. thujae populations must not contain the SR- or RR-stereoisomers of 2,12-, 2,13-, and 2,14-diacetoxyheptadecane. This result will allow development of a less expensive design for synthesizing the pheromone.

Okanagan Valley

AbstractSex pheromone traps to control codling moth by male removal was evaluated in three orchards in the Okanagan Valley. The program was successful in only one of the three orchards. This orchard is completely isolated and codling moth control has been obtained for 5 years. In a second orchard, codling moth populations were reduced by sprays prior to the male removal program. The program was successful in 1977, as the per cent injured fruit was only 0.6. In 1978, the codling moth capture rose sharply and at harvest the per cent injured fruit was 8.0. There was a high infestation in the third orchard when the program was initiated, and in 1976, the per cent injured fruit dropped to 10.4% from 60.0 in 1975. The per cent fruit injured by codling moth rose to 37.4 in 1977 and to 60.2 in 1978 under the male removal program. Our data show that this method of control is effective only under special circumstances, where codling moth populations are low and where isolation precludes reinfestation.

Abstract The female sex pheromone of Bonagota (=Phthteochroa) cranaodes (Meyrick) is a blend of (E,Z)-3,5-dodecadienyl ajcetate (E3,Z5-12:Ac) and (Z)-9-hexadecenyl acetate (Z9-16:Ac) according to analysis of pheromone - gland extracts and field trapping in apple orchards. This is the first time that E3,Z5-12:Ac has been identified as a lepidopteran sex pheromone. Traps baited with 100 μg E3,Z5-12:Ac were attractive over 15 weeks in the field and were as effective as traps baited with virgin females. Addition of Z9-16:Ac to E3,Z5-12:Ac at ratio of 1:10 had a significantly increase of male moths. The addition of the Z,E and Z,Z isomers to rubber septa baited with E3,Z5-12:Ac did not modify B. cranaodes male attraction, but 10% of EE enhanced trap catch.

AbstractPheromone traps were more efficient than blacklight traps for detecting and monitoring adult populations of fall armyworm, Spodoptera frugiperda (J.E. Smith), in southwestern Ontario. Several dispenser–chemical combinations were strongly attractive but best results were obtained with sticky traps baited with rubber septa impregnated with combinations of (Z)-9-dodecenyl acetate and (Z)-9-tetradecenyl acetate.

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.

AbstractCodling moth populations in six orchards in the Okanagan and Similkameen valleys of British Columbia were monitored for 2 seasons with traps baited with trans-8, trans-10, dodecadien-1-ol, the sex pheromone of the codling moth, Laspeyresia pomonella (L.). Sprays were applied if traps within the orchard captured two or more moths per trap per week during 2 consecutive weeks. Traps installed in neighboring orchards minimized male moth influx. A 43.1% reduction in the number of required cover sprays for codling moth control was obtained over a 2-year period compared with a standard three spray program. Fruit injured by codling moth in monitored orchards varied, but was less than 1% in all but one orchard.

The Garry Oak Ecosystem (GOE) is a fragmented and endangered ecosystem in Canada, and is currently the focus of conservation and restoration efforts in British Columbia. However, little is known about the basic biology of GOE forbs, or their relationships with pollinating insects. We monitored wildflowers and their insect visitors in 25 quadrats within a 25 × 25 metre plot, located in a fragment of the GOE near Duncan, British Columbia, for six weeks (the majority of the flowering period). Overall, 21 native and non-native forb species flowered in our quadrats during the survey, and we observed an additional six forb species flowering outside of our quadrats. Eight forbs were visited within quadrats by a total of 13 insect taxa, identified to morphospecies. Visits by eight additional morphospecies were observed outside of the quadrats. In general, visitation was low; however, most insect morphospecies were observed visiting more than one plant species, and most plant species were visited by more than one insect morphospecies, suggesting that pollination may be generalised in this community. A Chi-squared analysis indicated that insect visitation was not proportional to the relative abundance of forbs, with higher than expected visitation to Common camas (Camassia quamash), and no observed visits to 11 species, most with very small (putatively unattractive) flowers. The most frequent insect visitor was the introduced Honeybee, Apis mellifera, followed by native mason bees (Osmia spp.) and mining bees (Andrena spp.). Our observations provide baseline data for future, detailed studies that should investigate the importance of plant-pollinator mutualisms for sustainability of populations and communities in this rare ecosystem.
