Essential amino acids for the growth of Sogatella furcifera were investigated. Insects were fed on a chemically-defined diet lacking one amino acid from the stage immediately after hatching. All the nymhs developed into adults on diets lacking any one of the following amino acids: alanine, aminobutyric acid, arginine, asparagine, aspartic acid, cysteine, cystine, glutamic acid, glutamine, glycine, histidine, homoserine, isoleucine, leucine, lysine, methionine, phenylalanine, proline, serine, threonine, tryptophan, tyrosine and valine. Therefore, no single amino acid is essential for growth. However, growth was markedly delayed with diets lacking either cysteine or methionine.
