This work aims to identify the species of fruit flies and their parasitoids associated to native fruit of Spondias spp. (caja S. mombin L., umbu-caja Spondias sp., umbu S. tuberosa Arr. Câm.) and wild plum Ximenia americana L., in the State of Piaui, Brazil. Samples (63) of fruits were collected from November 2009 to July 2010, totalizing 4,495 fruits and 46,906 kg. It was possible to obtain 10,617 puparia, from which 4,497 tephritids and 1,118 braconid parasitoids emerged. Regarding Spondias spp., the highest occurrence was Anastrepha obliqua (Macquart), with 100% for umbu and umbu-caja. Caja presented an average of 99.52% of A. obliqua, 0.46% of Anastrepha fraterculus (Wied.) and 0.97% of Ceratitis capitata (Wied.). Wild plum percentages were 97.83% for A. alveata Stone and 2.17% for A. fraterculus. Infestation rates were 429.2, 178.4, 158.9 and 43.3 puparia/kg in umbu-caja, caja, wild plum and umbu, respectively. Pupal viability was 77.8%, 69.3%, 52.5% and 41.1% to umbu, wild plum, umbu-caja and caja, respectively. By analyzing the sample parasitoids, the percentage was 21.39% for the Doryctobracon areolatus (Szépligeti) species and 78.61% for Opius bellus Gahan. For the first time, it was recorded in Brazil X. americana as a host to A. alveata, as well as D. aleolatus and O. bellus as parasitoids of A. obliqua and A. alveata in Piaui.
