Mean SE of five observations. Within the rows, means followed by different letters are significantly different. Food utilization efficiency measures: GR: growth rate, CR: consumption rate, RGR: relative growth rate, CI: consumption index, AD: approximate digestibility, ECI: efficiency of conversion of ingested food, ECD: efficiency of conversion of digested food, LS: larval survivability.
