Reinvestigation of oak leaf roller sex pheromone components and the hypothesis that they vary with diet.

ABSTRACT

The sex pheromone of the oak leaf roller, Archips semiferanus, was identified as a specific blend (6733) of trans-11- and cis-11-tetradecenyl acetates. The pheromone blend of females from a semisynthetic diet and from three oak species did not vary significantly. Males from these diets responsded in the laboratory and the field only to treatments approximating the 67 33 blend. These findings conflict with the hypothesis that the composition and perception of month sex pheromones vary with slight changes in diet.
