Identification of sex pheromone component of spruce budmothZeiraphera canadensis.

The analyses of virgin female sex pheromone gland extracts by gas chromatography (GC), GC-electroantennographic detection (GC-EAD) and GC-mass spectrometry (GC-MS) followed by field-trapping experiments, have identified (E)-9-tetradecenyl acetate (E9–14:Ac) as the primary sex pheromone component of the spruce budmoth,Zeiraphera canadensis. Dosages of 1.0–100.0 ⧎g ofE9–14:Ac impregnated in rubber septa provide effective trap baits.
