Abstract : Fruit flies (Diptera: Tephritidae) belong nowadays the main constraints to production and marketing of fruits in Sub-Saharan Africa. Knowledge of the species diversity of these pests and their population dynamics in any ecosystem is a prerequisite for the implementation of programs to control these pests. It is in this context that an inventory, an estimate of the prevalence and monitor the population dynamics of subservient Tephritidae fruit were made for one year in the urban area of Lomé (Togo). Four and 3 types of traps parapheromones were used to capture flies. Three species were identified Tephritidae: Bactrocera invadens, Bactrocera cucurbitae and Dacus bivittatus. Two species (B. invadens and B. cucurbitae) are invasive species (D. bivittatus) is native. Among invasive species, B. invadens is of considerable economic importance because its average prevalence (23.68 flies/trap/day) is higher than that of other species. The period of outbreak of B. invadens coincides with the ripening of mangoes, its main host plant. Preserving the quality of mangoes must pass through the implementation of appropriate programs for population management of Tephritidae in Togo.
