Fig. 3. Age of fruitflies, whose lysates are used as a dietary source of protein, modulates the life span of female D. melanogaster.

(A) Survival curves of female fruitflies reared on diets containing various carbohydrate and protein sources: Control (1X sugar and 1X yeast; n = 85), 1X fly lysate (1X sugar and 1X fly lysate; n = 100), 0.5X fly lysate (1X sugar and 0.5X fly lysate; n = 96), 0.5X sugar and 0.5X fly lysate (n = 105), and 0.5X sugar only (n = 95). The diet based on 1X fly lysate supports the normal life span of D. melanogaster. (B) Kaplan-Meier survival curves of female fruitflies subjected to diets containing lysates of young (n = 121) or old flies (n = 96). The log-rank test was used for statistical analysis. See table S2 for life-span analysis of individual dietary groups.
