Green fruitworm
Damage caused by the Green fruitworm
Only larval stages of green fruitworm cause damage to leaves and fruits of many plant species including apple, peach and cherry. Newly hatched larvae of green fruitworms generally feed on the leaves, buds, blooms and small fruits. Damaged fruits show sunken pits on their surface and they fall off trees prematurely. Damaged fruits that remain on trees until harvest also shows sunken and corky injuries. Mature larvae can burrow anterior end into fruits and feed on its content. In case of severe infestation, larvae of green fruit can completely defoliate their host plants.

- Biology
-
Green fruitworms overwinter as adults on the ground. Early in the spring, adults move from their overwintering sites to blooming trees. After mating, females lay eggs on the bark of young branches and near to leaf buds. Eggs start hatching into first stage larvae when fruit buds start to grow. Hatched young larvae then start feeding on the leaves, buds and small fruits until they become mature. Mature larvae then pupate in the soil and life cycle continues. Green fruitworms generally complete one generation in a year.
