Sex pheromone ofPandemis heparana (Den. and Schiff.) (Lepidoptera:Tortricidae).

ABSTRACT

90% (Z)-11-tetradecen-1-yl acetate, 5% (Z)-9-tetradecen-1-yl acetate, 5% (Z)-11-tetradecen-1-ol, dodecyl acetate (<1%), and tetradecyl acetate (<1%) were identified from gland extracts ofPandemis heparana females by gas chromatography and gas chromatography-mass spectrometry analysis (including mass fragmentography studies), chemical characterization, total synthesis, laboratory and field bioassays. In the field, a mixture of (Z)-11-tetradecen-l-yl acetate and (Z)-9-tetradecen-l-yl acetate (95∶5) was found to be essential for attractiveness ofP. heparana males.
