The proteins of larvae, pupae and adults (females, males) of almond seed wasp Eurytoma amygdali -Eurytomidae, were extracted and electro - pHoresied on polyacrylamide gel. Results showed clear differences in the quality of proteins between larvae, pupae and adults. The accumulation of proteins started in the initial stage of larva and increased clearly in the second stage with a continuation in the first stage of pupa, but mostly absent with the progress of the pupa in a lifetime. It was observed that there were differences between the proteins found in females from those in males by showing the presence of a protein when the females from the age of one day and continued its existence until the age of 7 days and this protein was essential in the formation of the yolk of ovocytes.
