Abstract

The chemicals cis (Z) and trans (E)11-tetradecenyl acetate (11–14:Ac), trans 11-tetradecen-1-ol (E11–14:OH) and trans 11-tetradecenal (E11–14:Ald) were isolated from unmated female Choristoneura orae Freeman and shown to be highly attractive when used as lures in sticky traps. The identification of these components of the sex pheromone facilitates the separation of C. orae from other Pinaceae-feeding Choristoneura in the same area.

Résumé

On a isolé de la femelle non accouplée de Choristoneura orae Freeman les composés chimiques cis (Z) et trans (E) 11-acétate tétradecenyl (11–14 : Ac) trans 11-tétradecen-1-ol (E11–14 : OH) et trans 11-tétradecenal (E11–14 : Ald) qui se sont révélés très attractifs comme appâts dans des pièges englués. L'identification de ces composés de la pheromone sexuelle facilite la distinction de C. orae d'autres espèces de Choristoneura inféodées aux Pinaceae dans la même région.
