Sexually dimorphic effects of dietary sugar on lifespan, feeding and starvation resistance in Drosophila

Figure 2. Sexually dimorphic feeding response to sugar and its relationship to female egg laying. (a) The proportion of male and female flies observed feeding on day 7 on diets with different relative amounts of sucrose (1x to 8xS). Medians (solid line) and first and third quartiles (shaded areas) are shown. Statistical analysis is given in Table 2. (b) Bar charts showing the number of eggs laid per female per day on days 8 to 50 (measured every week, n=10) on diets with different relative amounts of sucrose (0.5x to 8xS). (c) Egg laying on day 8 (n=10) is correlated to average proportion of flies feeding on day 7. The black line shows the parameters of a LM fit (adjusted R2=0.91, p<2x10-16).
