Improving the mass-rearing process of Anastrepha ludens Loew (Diptera: Tephritidae) using a pre-gelatinized starch larval diet
The larval diet for mass rearing of the Mexican fruit fly, Anastrepha ludens (Loew) represents 30% of the total cost of production and generates great amount of solid wastes with high contents of protein due to low consumption by larvae. In order to reduce the costs of production and generation pf s...

| description | The larval diet for mass rearing of the Mexican fruit fly, Anastrepha ludens (Loew) represents 30% of the total cost of production and generates great amount of solid wastes with high contents of protein due to low consumption by larvae. In order to reduce the costs of production and generation pf solid waste, a texturized diet with pre-gelatinized starch was developed, which in comparison to a standard diet, increased the number of larvae per gram of diet from 4.6 to 5, transformation from egg to larva increased from 60 to 76%, larval weight increased from 29.2 to 29.8 mg, and pupal weight from 18.6 to 19.8 mg. It was determined that the percentage of egg hatch at the time of seeding on the diet affected the yield and the transformation from egg to larva. We found that diets seeded when a minimum egg hatch of 40% is reached gave best results. The optimal amount of diet per tray was found to be of 3.0 kg in a layer of 2.0 cm of depth. |

La dieta larvaria para cría masiva de la mosca mexicana de la fruta, Anastrepha ludens (Loew) representa el 30% del costo de producción y genera una gran cantidad de desechos sólidos conalto contenido de proteína como resultado de un bajo aprovechamiento por las larvas. Para reducir los costos de producción y la cantidad de desechos sólidos generados, se desarrolló una dieta texturizada con almidón pre-gelatinizado, con la cual se incrementó la producción en comparación con una dietaestandar de 4.6 a 5 larvas/g de dieta, la transformación de huevo a larva paso de 60 a 76%, los pesos de larva y pupa de 29.2 a 29.8 y de 18.6 a 19.8 mg, respectivamente. Se determinó que el porcentaje de eclosión de huevo al momento de la siembra afecto el rendimiento larvario y la transformación de huevo a larva, estableciéndose una eclosión de huevo óptima de 40% al momento de la siembra. La cantidad óptima de dieta gélica en cada recipiente fue de 3 litros, con una capa de 2.0 cm de espesor.
