Abstract
A sex pheromone component was isolated from the hexane extract of fema les of the yellowish elongate chafer, Heptophylla picea Motschulsky by chromatography. The activity was examined by attraction in a glass tu be and in the field. The isolated component was analyzed by GC-MS and NMR, and its chemical structure was estimated to be 7,15-hexadecadien- 4-olide. The geometric isomerism was determined to be Z by comparative GCMS and NMR analyses of the isolated component and synthetic E- and Z-isomers. Synthetic (Z)-7,15-hexadecadien-4-olide demonstrated a pote nt attractiveness equal to that of two virgin females in the field.
