Resumen:
Abstract. The use of mitochondrial genes as molecular markers in insect evolutionary studies is useful to determine the origin and successfully identify organisms. We employed a data mining procedure that enabled us to align and trim sequences of the cytochrome oxidase I (COI) gene of 45 fruit fly taxa of the genus Ceratitis and 162 specimens of the Mediterranean fruit fly Ceratitis capitata (Wiedemann) collected from different regions of the world. With the first set of data, we assumed that the phylogenetics of the genus Ceratitis did not contain any monophyletic groups compared to conventional taxonomy. The population genetics study showed that the most diverse populations originated from sub-Saharan Africa, mainly from Guinea (Ghana, Benin and Nigeria) and the Horn of Africa (Kenya, Tanzania and Malawi). The least diverse population came from the Mediterranean where only two haplotypes were identified. Two genetic barriers were identified, one that isolated the Guinean population from the rest of Africa, and the other that separated the island populations (islands of Africa, Oceania and Hawaii) from the rest of the world. © 2024 Southwestern Entomological Society.
