Fruit flies (Diptera, Tephritidae) stand out as the most harmful pests to fruit crops in different parts of the planet. Biological pest control is one of the alternatives used in integrated management programs for fruit flies to help reduce the population density of these insects. This work aims to contribute to the expansion of scientific knowledge about the distribution of fruit flies in the territory of Pará, identifying species of occurrence, their host plants and their parasitoids. The study was conducted in a representative municipality of Nordeste Paraense, particularly in the municipality of Tomé-açu. The fruit samples were randomly collected. The emerged parasitoids were identified in the Entomology Laboratory of Embrapa Eastern Amazon and Embrapa Amapá. In the municipality of Tomé-Açu, acerola (Malpighia punicifolia), taperebá (Spondias mombin), guava (Psidium guajava), ingá (Inga edulis) and mango (Mangifera indica) are important population repositories of fruit fly species. Only Anastrepha species occur and infest fruit trees in the studied region. We report the first associations for the State of Pará: A. sororcula and A. fraterculus in carambola (Averrhoa carambola); A. obliqua in camu camu (Myrciaria dubia), cashew (Anacardium occidentale), abiu (Pouteria caimito) and mango. And yet, the first association of A. distincta in mango for Brazil.
