Sex pheromone of the codling moth: structure and synthesis.

ABSTRACT

The structure of a sex pheromone of the codling moth. Laspeyresia pomonella (L.), has been determined by spectrometric and chemical degradative techniques and by synthesis to be (2Z, 6E)-7-methyl-3-propyl-2,6-decadien-1-ol. In field cage tests the synthesized sex pheromone was as attractive as the natural, but neither was as attractive as ten virgin females per trap.
