The developmental diet has a significant effect on early fecundity (sum of all eggs laid during the first ten days after emergence). Note that individuals from both Indian and Slovak populations that developed on the low-yeast diet tend to have lower fecundity irrespective of the adult diet. On the other hand, the high-sugar larval diet significantly decreases early fecundity in both populations regardless of the adult diet. Data for each population and adult diet were analysed by one-way ANOVA followed by Tukey’s HSD test (α = 0.05). Plots marked with different letters are significantly different from each other. Box plots depict minimum, first quartile, median, third quartile, and maximum value. For detailed statistical analyses, see Additional file 1: Tables S1 – S6
