Chemical composition of sex pheromone of oriental fruit moth and rates of release by individual female moths

M J Lacey et al. J Chem Ecol. 1992 Aug.

Abstract

The sex pheromone emitted by individual calling females of the oriental fruit moth,Grapholita molesta, was trapped within glass capillaries, and the composition and release rates were determined by gas chromatography-mass spectrometry. Aerial release of (Z)-8-dodecenyl acetate ranged up to 25.3 ng/hr, while the mean release rate was 8.48 ± 7.26 ng/hr (±SD). The proportion of (E)-8-dodecenyl acetate to (Z)-8-dodecenyl acetate was remarkably constant (4.20 ± 0.60%). Significant amounts of dodecyl acetate were also recovered but, contrary to previous reports, only trace quantities of (Z)-8-dodecenol were detected in the effluvium.
