RESUMO:

Paraense fruit growing is constantly threatened by several phytosanitary problems, with insects belonging to the Tephritidae family (Insecta: Diptera) being among the main pests of this sector. However, despite the economic importance of these tefritids, information about the bioecology of these insects in some regions located in the Amazon biome is still scarce. Thus, our objective was to conduct a survey on the biodiversity of fruit flies and their parasitoids in the lower Tocantins microregion, Pará, Brazil. For this, passive and active collections were carried out in agroforestry yards located in the municipality of Cametá, Pará, Brazil. In the passive collection, McPhail traps were used, which were installed at 1.5m in height and used hydrolyzed protein as an attractive corn, while the active collection was carried out using guava, taperebá and star fruit, which were collected and stored in appropriate container and environment for obtaining the pupae of fruit flies and later their parasitoids. Shortly after the screening of the captured insects, the females of Anastrepha Schiner (Diptera: Tephritidae), as well as the parasitoid hymenopterans were tagged and later sent for identification at the Instituto Biológico de são Paulo. Soon after the identification of the fruit flies, the wealth, abundance and population fluctuation were determined, in addition to the niche modeling for the species with new reports for the region. As for parasitoids, the richness, abundance and influence of host fruits on the parasitism index were analyzed. Among the species found in this study, we highlight the Anastrepha zacharyi Norrbom flies, as the first report in the state of Pará, Brazil, this species being possibly endemic to the Amazon region. As for the community of tefritids associated with agroforestry yards, we find the following species; A. obliqua, A. distincta, A. striata, A. sodalis, A. leptozona and A. serpentina, the population fluctuation of these insects being influenced by the availability of hosts. Four species of parasitoids were recorded in this study; Doryctobracon areolatus (Szépligeti); Opius bellus Gahan; Utetes anastrephae (Viereck); Asobara anastrephae (Muesebeck), the first being the most abundant. Among the thefts collected, the Taperebá - Spondias mombin was the one that provided the highest rate of parasitism and the Carambola - Averrhoa carambola the lowest.
