Navel orangeworm—Amyelois transitella
Navel orangeworm larvae are milky white to pink with a dark reddish brown head. Two crescent-shaped
marks are found on the second segment behind the head. Adults have short snoutlike projections from the
of the head. They are grayish brown in color with irregular silver and dark markings on the wings.
Identification of species | Life
Caterpillars enter fruit or nuts and feed directly on the fruit and nutmeats. Fruit and nuts are contaminated
with large quantities of excrement and webbing.
Complete harvest rapidly and early, and remove and destroy
unharvested nuts from trees in winter. Natural
enemies may provide some control.
