Grapholitha molesta Busck.

The oriental fruit moth is very destructive on quince fruits in the orchard. Quince growing has been discontinued in most sections in the eastern United States mainly because of the ravages of this pest. Its larvae will eat their way through the flesh and often will honeycomb the fruits with tunnels. Alternaria rot, brown rot, and gray mold rot commonly follow oriental fruit moth injury.

The newer organic insecticides will effectively control the oriental fruit moth when properly applied. For the spray schedule consult the State agricultural experiment station or extension service.
