Ecosustainable alternatives, such as the Sterile Insect Technique (SIT), rely on the mass release of sterile male\u2010only progeny. However, sexing of male offspring requires the elimination of females during development. To overcome the loss of 50% of the progeny, the sex reversal of females into XX fertile males at embryonic stages by dsRNA injections was effective but not scalable. This study demonstrates the efficacy of Dicer\u2010substrate small interfering RNAs (DsiRNAs) as an alternative to long double\u2010stranded RNAs (dsRNAs) for targeting the sex determination genes\n                    <jats:italic>Cctransformer<\/jats:italic>\n                    and\n                    <jats:italic>Cctransformer\u20102<\/jats:italic>\n                    in the medfly, which causes full masculinization of XX individuals.

Additionally, thoracic injection of DsiRNAs in adult females achieved systemic gene silencing, reducing\n                    <jats:italic>Cctra\/Cctra\u20102<\/jats:italic>\n                    transcript levels in the ovaries by 75%\u201380% within 48 h. The reduced size of DsiRNAs compared to dsRNAs enhances their potential for alternative delivery methods, including embryo permeabilization, electroporation, and feeding in larvae or adult females. These findings provide a potential foundation for future scalable conditional masculinization of XX individuals rather than relying on female lethality, doubling male\u2010only productivity. Developing novel sexing methods as an alternative to transgenic approaches will expand the applicability of SIT.\n
