Pyramidal fruit orm is one of the most important pests of many fruits. All the larval stages of pyramidal fruitworm cause feeding damage to leaves and immature green fruits. In case of severe infestation, pyramidal fruitworms can seriously affect fruit yields.
Adults: Adult moths of pyramidal fruitworms are brown or gray in color with copper colored hindwings.
Eggs: Eggs are of pyramidal fruitworms are reddish violet in color.
Larvae/Caterpillars: Mature larvae are green in color with white markings and pale yellow stripes on each lateral side of the body. They have a pointed bump on the back at the tail region. They are about 1.5 inch long.
Pupae: Pupae of pyramidal fruitworm are brown in color.
Pyramidal fruitworm overwinter as egg stage. Eggs hatch early in the April through May into small caterpillars that start feeding on the leaves and immature fruits. While feeding caterpillars develop 4 developmental stages and mature. In June, mature larvae drop to the ground and then pupate in silken cocoons under the plant debris. Adult moths emerge from pupae in July. After mating, females lay eggs in fall as overwintering stages. Under favourable conditions, pyramidal fruitworm can complete 1 generation in a year.
