Parasitoids of Anastrepha fraterculus (Wiedemann) and Ceratitis capitata (Wiedemann) in-festing wild guava (Psidium guajava L.) and peach (Prunus persica (L.) Batsch) fruits in thesouthernmost extension of the Bolivian Yungas forest, in the Province of Tarija, were sur-veyed in Dec (early summer), Feb (mid summer) and Mar (late summer) 1999 and 2000. Theabundance patterns and diversity of fruit fly larval-pupal parasitoid species were similar topreviously published data for the southern and northern Yungas forests of Argentina. A totalof 1,600 guavas and 800 peaches, weighing 57.713 kg and 24.544 kg, respectively, were col-lected yielding 13,080 tephritid puparia, 78.4% of which were A. fraterculus and 21.6% Cer-atitis capitata (Wiedemann). We reared 712 larval-pupal parasitoids of the following species:Doryctobracon areolatus (Szépligeti), D. brasiliensis (Szépligeti), D. crawfordi (Viereck),Opius bellus Gahan Utetes anastrephae (Viereck) (all Braconidae, Opiinae), Aganaspis pel-leranoi (Brèthes) Odontosema anastrephae Borgmeier, and Lopheucoila anastrephae (Ro-hwer) (all Figitidae, Eucoilinae). Utetes anastrephae, O. anastrephae, and L. anastrephae arenew fruit fly parasitoid reports for Bolivia, as well as O. anastrephae in the South AmericanYungas forest. A thorough sampling of other C. capitata and Anastrepha host plants, mostlynative fruit species, will be necessary in the Yungas forest of Bolivia before further conclu-sions on abundance and composition of all fruit fly parasitoids can be reached.
