SUMMARY:

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 presents the results of the broadest survey for this area so far, integrating field sampling, collection cataloging, and a literature review, resulting in the processing of over 68,000 specimens. The occurrence of sixteen species was 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. Although regional sampling biases persist, this study establishes a new baseline for the Potiguar tephritid fauna, providing essential data both for integrated pest management and for understanding regional evolutionary processes.
