Abstract

Investigation of the European pine shoot moth pheromone has revealed three components in addition to the previously identified E-9-dodecenyl acetate (E9-12:Ac): E-9-dodecenol, dodecyl acetate, and dodecanol. Inclusion of E-9-dodecenol makes lures more attractive to the moth than unmated females or E9-12:Ac alone. Dodecyl acetate had no apparent effect when added to this more attractive mixture whereas dodecanol had an inhibitory effect. Dodecyl acetate appeared to mask the inhibitory effect of dodecanol when 0.3% or more of the former component is present in the lure. Relative proportions of components are critical in comparative testing or monitoring populations of the moth.

Résumé

L'analyse de la phéromone du perce-pousse européen du pin a révélé la présence de trois autres constituants avec l'acétate de dodécène-9E yl (E9-12 : Ac) : le dodécène-9E ol, l'acétate de dodécyle et le dodécanol. L'inclusion du dodécène-9E ol rend les appâts plus attractifs pour le perce-pousse que seulement les femelles vierges ou l'E9-12 : Ac. L'addition d'acétate de dodécyle à ce mélange plus attractif n'a eu aucun effet évident tandis que l'addition de dodécanol a eu un effet inhibiteur. L'acétate de dodécyle a semblé masquer l'effet inhibiteur du dodécanol lorsque 0.3% or plus du premier constituant est present dans l'appât. Les proportions de chaque constituant sont critiques pour les essais comparatifs ou la surveillance des populations du perce-pousse.
