[email protected] Simple Summary: Significant advances in the domestication and artificial rearing techniques for the South American fruit fly, Anastrepha fraterculus (Diptera, Tephritidae), have been achieved since the FAO/IAEA Workshop held in 1996 in Chile. Despite the availability of rearing protocols that allow the production of a high number of flies, they must be optimized to increase insect yields Citation: Mastrangelo, T.; Kovaleski, A.; Maset, B.; Costa, M.d.L.Z.; Barros, and decrease production costs. In addition, evidence of sexual incompatibility between a long-term C.; Lopes, L.A.; Caceres, C. mass-reared Brazilian strain and wild populations has been found. To address these issues, this study Improvement of the Mass-Rearing refined rearing protocols and assessed the suitability of a bisexual A.
