utilization efficiencies for L. migratoria and S. gregaria
fed one of a range of diets differing in protein:carbohydrate (P:C) ratio for
the duration of the 5th larval stadium. (A) Carcass nitrogen corrected for
protein intake, (B) carcass lipid corrected for protein and carbohydrate
intake and (C) unaccounted body mass (carcass dry mass minus nitrogen and
lipid) corrected for protein and carbohydrate intake.
