Damage from codling moth and oriental fruit moth is usually not widespread enough to warrant control measures, although several growers find it each season. OFM tends to be worse on stone fruit. This term refers to a class of larvae that are greenish and damage both apples and pears. One species, green with white stripes, appears to be more common than others. Young larvae feed on new leaves and flower buds.
Older larvae feed on flowers during bloom and on young fruit.
The damaged fruit usually drops. It can, however, remain on the tree, and will develop either a deep, corky scar or deep indentations, apparent at harvest. Most growers occasionally see a few green fruitworms, however, treatment is usually not necessary. Damage is very similar to that of green fruitworm, although it may occur throughout the season. The larvae is slightly smaller than fruitworm larvae, yellowish-green, and has a brown head.
