Sex pheromone of tortrix viridana: (Z)-11-tetradecenyi acetate as the main component

Abstract

In electroantennographic studies on Tortrix viridana males, (E)-11-tridecenyl acetate displayed the highest activity of all straight-chain alkenyl acetates. However, evidence obtained by gas chromatography coupled to an electroantennographic detector or a mass spectrometer indicated that the ubiquitous pherom one compound (Z)-11-tetradecenyl acetate is the main component in the T. viridana female secretion. This com pound and both (Z)- and ( E) -11-tridecenyl acetate were found to be attractants for T. viridana males in the field. (Z)-9- and (E)-11-tetradecenyl acetate were not attractive and reduced male catches when added to either (Z)-11-tetradecenyl acetate or ( E) -11-tridecenyl acetate. No evidence for synergistic effects was obtained. © 2015 Verlag der Zeitschrift für Naturforschung. © 1979, Walter de Gruyter. All rights reserved.
