Natural enemies
Natural enemies can effectively control diamondback moth. In Southern California, the ichneumonid wasp,
Diadegma insularis, has been identified as the most common parasite. It pupates within the cocoon
of the parasitized caterpillar. You can recognize it by the broad stripe around the pupa.
Trichogramma pretiosum may attack diamondback moth eggs.
