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.Keywords
