Growth of fourth instar <i>M. sexta</i> larvae transferred from sucrose to casein diets and vice versa.

<p>(A–E) Growth trajectory of fourth instar larvae transferred from sucrose to casein diets and vice versa. Day 0 larvae were fed 5.8% casein and 7% sucrose in the specified order, and their growth trajectory was monitored. The red dots indicate the timing of head capsule slippage (n = 8–20 for each treatment). Black circles indicate the animals that molted whereas grey circles represent the animals that ultimately died without molting. (F) The time taken for larvae to initiate a molt. Different letters represent statistically significant differences (ANOVA with Tukey-Kramer HSD test; p<0.05; n = 4–20). p<0.0001 for all statistically different pairwise comparisons except between larvae fed on casein for either one or two days and transferred to sucrose (p = 0.0002), and between those fed on normal diet and those fed on sucrose for one day followed by casein (p = 0.0008). Error bars represent standard errors.
