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), and Z-8-dodecen-1-ol (Z8-12:OH) were identified in the proportions 100:1:30:5:2 in female sex gland extracts of Grapholita 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 with Z8-12:Ac in the presence of a higher proportion of E8-12:Ac than in the female. Inclusion of the 14-carbon acetates did not augment G. funebrana catches but inhibited G. molesta. On the other hand, addition of Z8-12:OH at the level optimal for G. molesta reduced attraction of G. funebrana.
