Shipping biocontrol agents into hawaii
By 1975, populations of the fly had built up, and-along with other biocontrol agents-had effectively decreased Ageratina riparia stands in many areas of Hawaii Island.Īgent: Antiblemma acclinalis (Noctuoidea) It was released in Kona in 1974 at the 3400 foot elevation, and later at other locations on Hawaii's Big Island. Status: Procecidochares alani, a stem-galling fly, was collected at 2000 foot elevation in Mexico in 1973 as a potential biocontrol of Ageratina riparia (the so-called "Hamakua pamakani"). By 1975 the moth was well established, and-along with other biocontrol organisms-had significantly reduced Ageratina riparia infestations on the Big Island.Īgent: Procecidochares alani (Tephritidae) The moth was later released in Volcano and other areas of the Big Island. Status: Oidaematophorus beneficus, a plume moth, was brought from Mexico and released in 1973 on a Kona ranch for control of Ageratina riparia (the so-called "Hamakua pamakani"). In wetter areas, Ageratina riparia resprouted, but seedlings were subsequently shaded out.Īgent: Oidaematophorus beneficus (Pterophoridae) By 1976 this pathogenic foliar fungus had become widely distributed, and has been highly effective in reducing or eliminating Ageratina riparia populations in elevations between 2000 to 3500 feet on the Big Island. by some sources) was collected in Jamaica in 1974 and released on the Big Island of Hawaii in 1975 to control Ageratina riparia (the so-called "Hamakua pamakani").

Fungal infestation of plants during wet periods coupled with the impact of previously introduced insects has resulted in other plants invading monotypic stands and in some cases replacing them.Īgent: Cercospora sp. Status: No quantitative evaluations are available, but this fungus is considered effective against "Maui pamakani" ( Ageratina adenophora). Target: Ageratina adenophora (Asteraceae)Īgent: Entyloma compositarum (Entylomataceae) (For now, the scope of this site is limited to selected plant biocontrol targets information about biocontrol of other organisms is not currently included here, and only selected plant targets are covered.) For further information, contact hints) Selected biocontrol target species in Hawaii and the current status of each of one or more selected biocontrol agents released or considered for release for each target in Hawaii are presented here, along with links to supporting references.
