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

Abstract
In 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.
Résumé
Dans une expérience de piégeage dans une pépinière à graines de thuyas géants, Thuja plicata Donn × D. Don, abandonnée en Colombie-Britannique, nous montrons que l'attraction des mâles de la cécidomyie des cônes du thuya géant, Mayetiola thujae (Hedlin), au mélange de phéromones (2S,12S)-, (2S,13S)- et (2S,14S)-diacétoxyheptadécanes est réduite en présence d'un mélange de tous les autres stéréoisomères ou des trois stéréoisomères SR- ou RR-. En revanche, les trois stéréoisomères RS- restent sans effet significatif. La phéromone synthétique utilisée pour la surveillance des populations de M. thujae ne doit donc pas contenir de stéréoisomères SR- ou RR- des 2,12-, 2,13-, et 2,14-diacétoxyheptadécanes. Cette observation permettra de mettre sur pied une synthèse moins coûteuse de la phéromone.
