Abstract
Although ( E , E )- 8,10-Dodecadien-1-ol was reported to be a sex pheromone of the codling moth [ Laspeyresia pomonella (L.)], its presence in the moth was questioned, mainly because it has not been isolated. A computerized search of data from gas chromatography-mass spectrometry of a partially purified extract equivalent to 45 abdominal tips of female moths produced a mass spectrum that matched that of the authentic compound. Other data also confirmed the presence of the compound.
