Sex pheromone components of the pear fruit moth, Acrobasis pyrivorella (Matsumura).

We analyzed the sex pheromone of the pear fruit moth, Acrobasis pyrivorella, by means of gas chromatography-electroantennographic detection (GC-EAD) and GC-mass spectrometry. Two EAD-active compounds were detected in the pheromone gland extract of females. They were identified as (Z)-9-pentadecenyl acetate (Z9-15:OAc) and pentadecyl acetate (15:OAc).
