The total amount of carbohydrate (as glucose) decreased during the larval-pupal transformation by about 1 μmole/insect (about 20 per cent), and thereafter remained almost constant until emergence. Thus, during pharate adult development, the increase in chitin was balanced by a corresponding decrease in glycogen (these are the two principal carbohydrates; together accounting for about 94 per cent of the total). Glucose-oligosaccharides, trehalose, and a number of monosaccharides were also estimated. There was little evidence for the accumulation, at any stage, of l-lactate, l-glycerol-1-phosphate, α-alanine, glycerol, and/or d-sorbitol. 'High-energy' phosphate compounds decreased during the larval-pupal transformation and increased during pharate adult life. The R.Q. value increased from 0·72 in prepupae to 0·93-0·99 in late pupal and early pharate adult life, and then decreased to 0·78 in late pharate adult life. These data are discussed in relation to the information available on the changes in lipids, proteins, and amino acids in Lucilia. It is concluded that the energy requirements are provided principally by utilization of protein and fat (during pupal and late pharate adult development) and that the contribution of carbohydrate is very small. © 1967.
