TABLE 2.
Overall carbon net growth efficiencies, NGE*avg in BSF larvae, aged 1–5 days and until the estimated time of prepupae formation, calculated using Eq. 2, with rates of growth and feed assimilation calculated using the differential energy budget model in Figures 1C,D. Number of different feed substrates, n.
