Identification of two components of the sex pheromone of the moth,Epiphyas postvittana (Lepidoptera, Tortricidae)

Abstract
Two compounds, (E)-11-tetradecen-1-yl acetate and (E,E)-9,11-tetradecadien-1-yl acetate, have been identified in extracts of females of the lightbrown apple moth,Epiphyas postvittana (Walker). The two compounds are active as a coalitive pair and are present in extracts of females in a ratio of about 20∶1.
