Natural enemies of orange tortrix

Orange tortrix caterpillars have many natural enemies, including parasitic wasps in the genus Exochus, that attack larvae. Other parasites include Apanteles aristolilae and a tachinid fly, Nemorilla pyste. General predators also feed on the orange tortrix. Some of the most common general predators are green lacewings, damsel bugs, assassin bugs, bigeyed bugs, minute pirate bugs, and spiders.
