Sex Pheromone of Eupoecilia ambiguella: cis-9-Dodecenyl Acetate as a Major Component

Abstract The electroantennogram-active compound in abdominal tip extracts of E. ambiguella females was identified as cis-9-dodecenyl actetate. The compound was present at a level of 25 ng per female and absent in a male extract. The synthetic chemical shows prominent electroantennogram activity, elicits a mating dance response in the males, and is attractive in the field. The results indicate that cis-9-dodecenyl acetate is a major component of the E. ambiguella sex pheromone.
