One way Anova on ranks (Kruskal-Wallis) and Student-Newman-Keuls (comparisons); n=6; Different letters indicates significant differences (P<0,05) for the same column. Different numbers indicates significant differences (P<0.05) for the same line. L1 – L4 corresponds to the four larval instars and the pupal to L5; See Table 1 for food amounts supplied to each instar.
