Mosquitoes such as Aedes albopictus and Ae. aegypti are major vectors of diseases like dengue and Zika, posing significant threats to global public health. To combat these mosquitoes, methods like the sterile insect technique (SIT) and incompatible insect technique (IIT) are used, which rely on releasing large numbers of sterilized or modified males to suppress wild populations. However, the success of these programs depends on producing high-quality mosquitoes in laboratory settings, which requires optimized nutrition during the larval stage. This study investigated the role of larval diets in optimizing mosquito fitness for mass-rearing programs. Three diets with varying costs and protein sources were tested to identify the most effective option for large-scale rearing. The results indicated that a low-cost diet based on tortoise food improved mosquito survival, flight ability, and longevity, making it a promising alternative for cost-effective production. By identifying effective larval diets, this research contributes to improving mosquito mass-rearing practices, which are critical components of SIT and IIT operations. Future studies will focus on refining these diets and validating their effectiveness in the real world, supporting global efforts to combat mosquito-borne diseases.
