The female-emitted pheromone ofGrapholitha molesta (Busck), the Oriental fruit moth, was collected by holding females in glass flasks during calling. Flask washes were found to contain four pheromone components: (Z)-8-dodecenyl acetate and (E)-8-dodecenyl acetate in a 100∶7 ratio, and (Z)-8-dodecen-1-ol and dodecanol in a 100∶20 ratio. The ratio of (Z)-8-acetate to (Z)-8-dodecen-1-ol was approx. 100∶30. Approximately 0.1–0.2 ng of pheromone was recovered per female per hour of calling.
