Identification of a potential sex pheromone of the processionary moth, Thaumetopea pityocampa (lepidoptera, notodontidae)

The major component of the active fraction from the Thaumetopoea pityocampa (Denis and Schiff.) virgin female extract has been identified as (Z)-13-hexadecen-11-ynyl acetate on the basis of spectroscopic and microchemical reactions data. This is the first report of an acetylenic structure found in the insect pheromone field.
