Large amount of DNA is synthesized during larval development of Corcyra and this is conspicuously seen in the early-last instar. Ligation in early-last instar causes a decline in both DNA content and DNA concentration. Radiolabelling studies show a low rate of DNA synthesis in isolated abdomens, suggesting that hormonal factors from the anterior half of the larvae play a regulatory role in the DNA metabolism. Juvenile hormone I (JH-I) treatment of ligated early-last instar stimulates DNA synthesis with consequent increase in DNA content and DNA concentration.
