Abstract
The objective of this work was register the occurrence of Anastrepha species and parasitoids associated to fruits of Spondias mombin in three municipalities of the state of Amapa, Brazil. We collected fruits of S. mombin in the municipalities of Oiapoque, Porto Grande and Mazagao (10 samples per municipality, each one consisting of about 1 kg of fruit) in February and March 2014. We obtained 2,715 puparia, from which emerged 891 specimens of Anastrepha and 261 Hymenoptera. The infestation rates were variable, with the highest average amount recorded in Porto Grande (99.8 pupae/kg of fruit). We obtained four species of the genus Anastrepha : Anastrepha obliqua (Macquart), Anastrepha antunesi Lima, Anastrepha fraterculus (Wiedemann) and Anastrepha striata Schiner. Anastrepha obliqua was the most abundant species in the three municipalities. Of the 29 samples infested by fruit flies, only seven (24.1%) did not present parasitism. The highest mean percentage of parasitism was registered in Mazagao (18.9%). We obtained five species of parasitoids: Opius bellus Gahan (50.6% of total), Doryctobracon areolatus (Szepligeti) (26.8%), Asobara anastrephae (Muesebeck) (16.5%), Utetes anastrephae (Viereck) (5.7%) and Aganaspis pelleranoi (Brethes) (0.4%). Keywords: Amazon; Anastrepha ; Doryctobracon ; hog plum.

O Estado do Amapá está localizado na porção setentrional do Brasil, com área territorial de 143.453,70 km. O clima é equatorial com temperatura média anual de 26°C e precipitação de cerca de 2.700 mm anuais. Dispostos em câmaras climatizadas sob condições controladas de temperatura (27 ± 0,5o C), umidade relativa do ar (70 ± 10%) e fotofase (12h), sendo observados diariamente. Após a emergência dos insetos (moscas-das-frutas e parasitoides), estes foram acondicionados em recipientes de vidro, contendo etanol 70%, devidamente etiquetados, para posterior identificação
