In Hawaii several species of insect have been introduced with the purpose of being a biocontrol. Two weevils, Acythopeus burkhartorum and A. cocciniae, were introduced by the Department of Agriculture to Oahu and Hawaii. African vine moths (Melittia oedipus) were also released onto Oahu and Maui. On the island of Maui it appears that the A. cocciniae is established and are damaging leaves. The larva feed on the plant and the adults chew holes in the leaves. The moth has yet to appear successful in its purpose.
