Abstract

Laboratory bioassays and field tests demonstrated that the (+) enantiomer of endo-brevicomin is an antiaggregation pheromone for the western balsam bark beetle, Dryocoetes confusus Swaine. (+)-endo-Brevicomin significantly reduced the response of beetles of both sexes to the aggregation pheromone exo-brevicomin in laboratory bioassays and in field experiments using multiple-funnel traps. It also prevented attack on subalpine fir, Abies lasiocarpa (Hook) Nutt., trees baited with exo-brevicomin. The (−) enantiomer of endo-brevicomin was inactive. These results suggest that (+) or (±)-endo-brevicomin has potential for protecting selected trees from attack, or suppressing western balsam bark beetle activity in high hazard or infested stands.

Résumé

Les épreuves biologiques au laboratoire et les essais aux champs ont démontré que l’énantiomorphe (+) d’endo-brévicomine constitue une phéromone d’antiassemblage du scolyte occidental du sapin, Dryocoetes confusus Swaine. (+)-endo-Brévicomine a réduit significativement la réponse des deux sexes du scolyte à la phéromone d’assemblage, exo-brévicomine, pendant les épreuves biologiques au laboratoire et pendant les essais aux champs, en utilisant des pièges de cratères multiples. Elle a aussi empêché l’attaque au sapin du nord, Abies lasiocarpa (Hook) Nutt., amorcé d’exo-brévicomine. L’énantiomorphe (−) d’endo-brévicomine a été sans effet. Ces résultats suggèrent que (+)- ou (±)-endo-brévicomine ont le potentiel pour protéger des arbres sélectionnés contre l’attaque ou pour supprimer l’activité du scolyte occidental du sapin aux réserves forestières de grand risque ou infestées.
