The chemistry of the oak leaf roller sex pheromone is shown by means of microozonolysis and computerized gas chromatography-mass spectrometry to be dominated by an approximate 70 to 30 ratio of E- and Z-11-tetradecenyl acetates. Tetradecenyl acetates are undetectable in highly purified oak leaf, apple leaf, and corn extracts analyzed by gas chromatography-mass spectrometry. These results reflect negatively on previous reports and on the hypothesis that plant components might govern insect chemical communication systems.
