Physico- chemical study of Ceratitis capitata rearing diet

The inhibition of the microbial growth in the rearing diet of ceratitis capitata made it possible to increase the productivity in pupae. The follow-up of the microbial load and the physicochemical parameters of the diets used with varous microbial inhibitors (potassium sorbate in combination with sodium benzoate with varous amounts, on the one hand, and of another share, nipagine in combination with sodium benzoate also with varous amounts) during a rearing of ceratitis capitata on the laboratory scale made it possible to select the diet D as being the most favorable diet. Indeed, a stability of the physico chemical parameters as well as a weak evolution of the microbial load are noted in this diet. (author). 16 refs
