Biocontrol agent: ?
Status in Hawaii: (no status currently available; inquire)
REFERENCES

Biocontrol agent: Crasimorpha infuscata
Status in Hawaii: Crasimorpha infuscate (Lepidoptera, Gelechiidae), a stem-galling moth, was introduced to Hawaii from Brazil in 1961-1962 to control Christmasberry (Schinus terebinthifolius). Apparently, the moth did not become established.

Biocontrol agent: Episimus utilis
Status in Hawaii: Episimus utilis (Lepidoptera, Olethreutidae), a leaf rolling moth from Brazil, was released in Hawaii from 1954 to 1956 to control Christmasberry (Schinus terebinthifolius). The moth became established, but reportedly causes only minor damage to its host.

Biocontrol agent: Heteroperreyia hubrichi
Status in Hawaii: Heteroperreyia hubrichi (Hymenoptera, Pergidae), a foliage feeding sawfly from Brazil, has been studied in quarantine for its suitability as a biocontrol agent for Christmasberry (Schinus terebinthifolius). Host specificity of the sawfly was evaluated using 20 species from 10 plant families. The sawfly laid eggs on the native Hawaiian tree Rhus sandwicensis, but only 1% of larvae developed, compared to 70% development on the target species. Risk to all other test species was considered negligible. Because of the potential risk to Rhus sandwicensis, no request for release for the sawfly was made.

Biocontrol agent: Lithraeus atronotatus
Status in Hawaii: Lithraeus atronotatus (Coleoptera, Bruchidae), a seed-feeding beetle from Brazil, was introduced to Hawaii in 1960 as a biocontrol agent for Christmasberry (Schinus terebinthifolius). The beetle became established but reportedly causes only minor damage to its host.
REFERENCES

Biocontrol agent: Megastigmus transvaalensis
Status in Hawaii: Megastigmus transvaalensis (Hymenoptera, Torymidae), a seed-feeding wasp, was accidently introduced to Hawaii from South Africa. It has been attacking seeds of Christmasberry (Schinus terebinthifolius) since the 1970s.
