Biochemistry of development of the insect Dacus oleae. Evolution of free amino acids

Abstract

• 1.

  1. Changes in the levels of free amino acids were studied during the metamorphosis of Dacus oleae.

• 2.

  2. Alanine and glutamic acid occur in the highest concentrations.

• 3.

  3. The more general variation is that exhibited by aspartic acid, threonine, serine, glutamic acid, glycine, alanine, valine, methionine, isoleucine, leucine, histidine and tryptophan.

• 4.

  4. Their levels are not significantly affected during larva-pupa transition and decline in the adult stage.
