Larval diet is one of the key factors in establishing a mass-rearing/production system for Wolbachia-based approaches that promotes high-quality and high-performance adult mosquitoes at a low/reasonable cost. To identify a suitable larval diet for Aedes aegypti infected with the Wolbachia line (wMID) and wild-type lab-established line (MID), four diets with different protein sources (ranging from 42 to 75%) were compared: fish food (TIL), bovine liver powder (COW), porcine powder meal (PIG), and a mix standard laboratory diet (MFOOD). The COW diet for wMID and MID (without affecting survival to the pupal stage) showed a shorter time to pupation, and the average time was 6 to 7 days, respectively. No significant differences were observed on pupation for wMID and MID, which ranged between 92 and 95% and 96–98%, respectively. A larger pupae size was observed among the TIL, COW, and MFOOD diets for wMID; no differences were recorded for MID. With the COW diet, wMID (7.90 ± 0.06) and MID (7.76 ± 0.10) males had shorter development times from LI to emergence. The stability of the Wolbachia infection was not affected by the diets evaluated. Independently of the Wolbachia infection, all diets are suitable for mass-production and maintenance of Ae. aegypti. Overall, no negative impact was observed on the life history traits evaluated. Considering these results, along with the relative costs of the four diets, PIG and TIL are viable choices given their affordability, accessibility of ingredients in the area. These two low-cost and suitable diets could be used for the Ae. aegypti mass-rearing system in Mexico. [ABSTRACT FROM AUTHOR]
