Sex pheromone of the cranberry blossom worm, Epiglaea apiata.
The cranberry blossom worm, Epiglaea apiata (Grote) (Lepidoptera: Noctuidae), is a major pest of cranberries in New Jersey. The female sex pheromone of this moth was identified as a blend of (Z)-9-hexadecenyl acetate (Z9-16:Ac), (Z)-9-tetradecenyl acetate (Z9-14:Ac), and tetradecyl acetate (14:Ac) by gas chromatographic-electroantennographic detection and gas chromatography-mass spectrometry. The ratio of the components in extracts of the female pheromone gland was determined to be 65:2:33 of the Z9-16:Ac, Z9-14:Ac, and 14:Ac, respectively. The double bond positions of the pheromone components were confirmed by dimethyl disulfide derivatization. In addition to the above three components, a mixture of C4-C10 aliphatic acids was present in both gland extracts and effluvia collections, and the acids elicited significant EAD responses from male moth antennae. However, addition of the C4-C10 aliphatic acids to the pheromone blend did not significantly increase trap captures. Three-hundred- and 1000-microg doses of a synthetic blend containing Z9-16:Ac, Z9-14:Ac, and 14:Ac (65:2:33), on a rubber septum were more attractive to males than lower doses.
