摘要
An apparently good, nutrient-rich plant can be relatively short of phenylalanine for 5th-instar nymphs of S. gregaria. Supplementary phenylalanine invariably increased the efficiency of conversion of ingested food to body substance, showing that this was the limiting nutrient. Relatively large quantities of phenylalanine are required for cuticle protein over a few days in the 1st half of the instar, which is when this amino acid is at a premium.
