Amino-acid synthesis in adult Dacus oleae (Gmelin) (Diptera Tephritidae) determined with [U-14C] glucose.
The ability of adult Dacus oleae for amino-acid synthesis from [U-14C] glucose was investigated. The relatively high specific activity radiometric measurements indicated that both sexes were able to synthesize the amino acids: alanine, aspartic acid, cystine, glutamic acid, glycine, hydroxyproline, proline and tyrosine; therefore, these amino acids are considered as nutritionally dispensable for D. oleae. On the other hand, the amino acids: arginine, histidine, leucine, isoleucine, lysine, methionine, phenylalanine, serine, threonine, and valine, showed a very low specific activity and therefore are considered as nutritionally indispensable. It was not possible to conclude about tryptophane, since the acid hydrolysis destroyed this amino acid.
