Abstract
The female-produced sex attractant pheromone of Coloradia velda has been identified by a combination of analytical methods and field tests as a blend of (10E,12Z)-hexadecadien-1-yl acetate (10E,12Z–16:Ac), (10E,12E)-hexadecadien-1-yl acetate (10E,12E–16:Ac), and (10E,12Z)-hexadecadien-1-ol (10E,12Z–16:OH) in a 10:1:0.33 ratio, respectively. The corresponding aldehyde (10E,12Z–16:Ald) was also found in extracts of female pheromone glands, but in blends with 10E,12Z–16:Ac and 10E,12E–16:Ac at low doses did not significantly increase the attractiveness of baits to male moths.
