SayedAbstractTo improve the mass rearing of Peach Fruit Fly, Bactrocera zonata different concentrations of Cacao, Curcuma and Selenium were added to the larval diet. The effects of these additives on the biological characteristics were evaluated. The pupal weight, adult emergence, sex ratio, adult survival, pupal production and adult flight ability were studied to evaluate the mass rearing quantity and quality. In addition, the elements compositions of adult stage were carried out as a monitor for B. zonata vitality. The results indicated that the concentrations of 1.0 gm/kg Cacao, 1.5 gm/kg Curcuma and (0.01 and 0.02 gm/kg) of Selenium were the most pronounced promising concentration to the insect fitness as compared to the other concentrations. In these concentrations, the pupal productions, pupal weights and flight ability of adult flies were clearly higher than the control treatments. Also, the major and trace elements P, S, Cl, K, Ca, Fe, Cu, Mg and Zn of male and female flies previously fed as larvae on selected concentrations of additives were analysed. Addition of 1.5 gm of Curcuma and 1.0 of Cacao increased the Cl of both male and female flies, while addition to both 0.01 and 0.02 gm/kg of Selenium increased the P and Mg contents of the both sexes. Also, some values of tested elements are varied by the differe...
