- Fruits of cultivated and wild hosts were randomly sampled in municipalities Vélez-Santander and Boyacá departments of Colombia S.A. for Jul. 2004 to Aug. 2005. 547 samples were collected (47 plant species and 18 families). A total of 13.566 specimens of Diptera emerged of the families: Tephritidae, Richardiídae, Lonchaeidae, Otitidae, Syrphidae, Tabanidae and Muscidae .Eighty six percent – 11.664 - were tephritids of the genus Anastrepha (A. fraterculus, A. striata, A. distincta, A. grandis), Blepharoneura sp., Toxotrypana curvicauda. From the same samples emerged 565 specimens of Hymenopteran larval – pupal parasitoids, 498 of them (88.14%) emerged from tephritids and they were identified as Aganasphis pelleranoi, Odontosema anastrephae, Dorytobracon crawfordi, Utetes anastrephae, Microcrasis sp., Asobara sp. Aceratoneuromyia indica, Pachycrepoideus videmmiae, Tetrastichus giffardii and Trichopria sp.; Spilomicrus sp. were recovered from Richardia sp. and Melanoloma viatrix and 64 specimens, identified as Aganasphis pelleranoi, Utetes anatrephae and Lopheucoila anastrephae emerged from 1.637 Neosilba sp. The overall rate of parasitism was 4,75%. However, parasitism for each parasitoid species varied considerably according with the host plant. Predators of Anastrepha spp. and stage preyed were directly observed in field and laboratory. The most abundant were ants (Hymenoptera: Formicidae) Pheidole sp., Solenopsis sp.and Crematogaster sp.; the vespid Polystes sp.; one morphospecies of spider (Saltidae); two morphospecies of Coleoptera:Staphylinidae; one morphospecies of Dermaptera:Forficulidae ; and one morphospecies of Hemiptera Reduviidae : Harpactorinae.
