Effects of a high sucrose diet on Drosophila metabolism. Following eclosion, adult flies were raised for ten days on a diet of yeast extract (15%, all contents w/V) and differing amounts of sucrose as indicated. Flies were harvested, weighed and their glucose, glycogen and trehalose levels determined in whole body extracts in at least triplicate. Flies show weight gain with increased food content (1-way ANOVA p < 0.0001; with post-test for linear trend p < 0.0001), but no changes in stored carbohydrates when on non-starvation diets. Shown is a representative of two independent experiments.
