Sex and mating dependent differences in nutrient preference for sucrose or yeast in D. melanogaster. To measure ingestion of yeast, flies were given a choice between the two food options wherein only food deficient in sucrose but containing 4% yeast extract (4%Y) contained a radiolabeled tracer (white bars). To measure ingestion of sucrose, flies were given a choice between the two food options wherein only diet deficient in yeast but containing 5% sucrose (5% S) contained a radiolabeled tracer (black bars). (A) Results of a ‘nutrient preference’ assay demonstrating the differences in dietary preferences of males and females in the w1118 strain. (B) Differences in dietary consumption of yeast and sucrose in virgin and mated females in the w1118 strain. In each assay four sets of 15 to 20 whole body flies were analyzed.
