Natural enemies of Amorbia

Various natural enemies attack egg, larval, and pupal stages of amorbia. One of the most effective egg parasites is the tiny wasp, Trichogramma platneri. Parasitized eggs are black. A tachinid fly and several parasitic wasps attack the larvae stages. The tachinid fly attaches its eggs near the head of the larva and the emerging maggots bore into the amorbia larva to develop inside. Another larval parasite is the larval stage of the parasite Bracon. The parasitic wasp, Brachymeria ovata, is a pupal parasite, and adult wasps exit from Amorbia pupae.
