SUMMARY:

Fruit farming in Rio Grande do Norte, a strategic economic sector, faces phytosanitary challenges imposed by fruit flies (Tephritidae). This work aimed to mitigate historical knowledge deficits regarding the diversity, ecology, and morphology of this group in the state through two complementary approaches. The first chapter conducted a macroecological survey, integrating field sampling, collection cataloging, and bibliographic review, resulting in the processing of over 56,000 specimens. Seventeen species were confirmed, with numerical dominance of the generalists Anastrepha sororcula Zucchi, 1979 e Ceratitis capitata (Wiedemann, 1824) in agroecosystems, while native species showed strong specialization and seasonality in local biomes. The second chapter investigated, via linear and geometric morphometrics, sexual dimorphism in Anastrepha macrura, a little-studied native species, detecting no significant differences between sexes in the analyzed somatic structures. It is concluded that, although regional sampling biases persist, the study establishes a new baseline for the Potiguar tephritid fauna, providing essential data both for integrated pest management and for understanding regional evolutionary processes.
