Population dynamics of three Bactrocera spp. fruit flies (Diptera: Tephritidae) and two introduced natural enemies, Fopius arisanus (Sonan) and Diachasmimorpha longicaudata (Ashmead) (Hymenoptera: Braconidae), after an invasion by Bactrocera dorsalis (Hen

► Oriental fruit fly was discovered on Tahiti in 1996. Eradication programs failed. ► Fopius arisanus was released in 2002. By 2009, mean parasitism was 65%. ► Diachasmimorpha longicaudata was released in 2008, but parasitism has been <5%. ► Bactrocera dorsalis has displaced Bactrocera tryoni and Bactrocera kirki in many host fruits. ► This is the most successful example of fruit fly biocontrol outside of Hawaii.
