From abdominal tips of virgin females of the Asiatic leafroller moth, Archippus breviplicanus WALSINGHAM, (E)-11-tetradecenyl acetate (compound A) and (Z)-11-tetradencenyl acetate (compound B) were isolated and identified as sex pheromone components. These two compounds were individually inactive, but a potent biological activity was revealed by mixing them. The ratio of compound A to compound B was 70 to 30 in virgin females. Tetradecyl acetate was also detected in virgin females. Mixtures of synthetic (E)-11-tetra-decenyl acetate and (Z)-11-tetradecenyl acetate in the ratio of 75 : 25 to 65 : 35 strongly attracted the male Asiatic leafroller moths in the field. The attractiveness of the mixture of the two compounds (total 1 mg, in the ratio of 70 : 30) was as strong as that of ten virgin females. Tetradecyl acetate showed a weak synergistic effect but dodecyl acetate did not.
