How to Manage Pests

Pests in Gardens and Landscapes

Omnivorous leafroller—Platynota stultana

Omnivorous leafroller caterpillars feed within nests they build by tying leaves or leaves and fruit together with silk webbing. Mature larvae ae green to cream colored but so translucent that you can see the main blood vessel running down their backs. Their head and the thoracic shield just below the head is brown.


Omnivorous leafrollers feed on a wide variety of vegetables, fruit trees and ornamental plants. When they feed between leaves and fruit they can cause substantial fruit scarring. Larvae do not burrow into fruit. Damage to leaves is not usually severe enough to warrant control.


Clean up gardens by removing host weeds and trash. Hand removal of webbed leaves and larvae can help control caterpillars in vegetables. General predators and parasites including a tachinid fly Erynnia tortricis and Trichogramma wasps may attack larvae or eggs. Treatment should not be required in vegetable gardens.
