Status of Acythopeus burkhartorum as a biocontrol agent for Coccinia grandis 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." (info from Marianne E. Chun (http://www.hear.org/pcsu/techreports/pdfs/pcsutechreport00129chun.pdf accessed 10 August 2009); info as of June 2000)

Introductions for biological control in Hawaii 1997-2001
The introduction of 16 insect and five fungal species to control six weeds and four insect pests in Hawaii from 1997-2001 is discussed in a paper by the Hawaii Department of Agriculture (Proceedings Hawaiian Entomological Society, 2003).

Biological control of ivy gourd, Coccinia grandis (Cucurbitaceae), in Hawaii
Three insect biologlcal control agents collected in Kenya have been introduced into Hawaii to combat the exotic weed ivy gourd (Coccinia grandis). The clearwing moth, Melittia oedipus, was released in 1996. The larvae of this moth bore into the mature vines and roots of ivy gourd. It is now established in Hawaii. Two additional agents, which belong to a group known as the African melon weevils, were released in 1999. The first, Acythopeus burkhartorum, forms galls on young shoots. The second, Acythopeus cocciniae, mines ivy gourd leaves. Aspects of the project--including host range testing--are discussed.
