Abstract
Z-8-Dodecenyl acetate (Z8–12∶Ac),E-8-dodecenyl acetate (E8–12∶Ac),Z-8-tetradecenyl acetate (Z8–14∶Ac),Z-10-tetradecenyl acetate (Z10–14∶Ac), andZ-8-dodecen-1-ol (Z8–12∶OH) were identified in the proportions 100∶1∶30∶5∶2 in female sex gland extracts ofGrapholita funebrana, accompanied by saturated acetates from 12 to 20 carbons with tetradecyl acetate predominating.Z10–14∶Ac has not previously been described as a lepidopteran sex pheromone component. Best attraction of males is obtained withZ8–12∶Ac in the presence of a higher proportion ofE8–12∶Ac than in the female. Inclusion of the 14-carbon acetates did not augmentG. funebrana catches but inhibitedG. molesta. On the other hand, addition ofZ8–12∶OH at the level optimal forG. molesta reduced attraction ofG. funebrana.
