Speckled green fruitworm - Orthosia hibisci (Guenee)
Home > Pest management > speckled green fruitworm
Speckled green fruitworms have one generation per year. Pupae overwinter in the soil and adults emerge starting in very early spring. Egg hatch occurs at the half-inch-green stage.
Larvae feed on leaves, buds and developing fruit. Most damaged fruit will drop prematurely. Larval feeding results in deep, corky scars. Injury may be con-fused with that caused by early RBLR feeding, but is usually deeper. Damaged fruit
