[Protein metabolic change in the tissues of Aporia crataegi L. under the action of the nuclear polyhedrosis virus].

Changes in protein metabolism in the hemolymph, fat body, intestine, and gonads of Aporia crataegi L. caterpilars under the influence of nuclear polyhedrosis virus were studied. Electrophoresis in polyacrylamide gel was used to study acid and basic proteins of insect tissues normally and after virus infection. The virus infection was shown to result in sharp changes of the protein spectrum of various tissues and organs, particularly 3 days after infection. The main changes consisted in the loss of coordination of age cellular protein synthesis and formation of new virus-specific proteins.
