Biocontrol agent: Acythopeus burkhartorum
Status in Hawaii: "While this species is not capable of killing ivy gourd, the galls are an energy sink and may slow down growth of young vines. It was first released in August 1999 in Waimanalo on the island of Oahu and in December 1999 in Kailua-Kona on the island of Hawaii." (Chun); "establishment of A. burkhartorum on Oahu is marginal, apparently restricted largely to sites in heavy shade, and the single release of this species on Hawaii evidently has failed to establish a viable population."

Biocontrol agent: Acythopeus cocciniae
Status in Hawaii: "Combined damage from larval and adult feeding can be quite severe. Acythopeus cocciniae was first released on Oahu in November 1999 and in Kona one month later. It has been recovered at all release sites on both islands."

Biocontrol agent: Melittia oedipus
Status in Hawaii: "Melittia oedipus was first released on the slopes of Punchbowl, Oahu, in August 1966. From that date to August 1999, approximately 21,600 adults and 16,000 larvae were released on Oahu. The moth is now well established and vines have thinned out substantially."
