Changes in carbohydrates and lipids during embryonic development of Antheraea mylitta (Lepidoptera).

ABSTRACT

Changes in carbohydrate and lipid metabolism during embryonic development in Antheraea mylitta were studied. While carbohydrates were metabolized during early embryogenesis, lipids were catabolised at the later stages. A significant increase in both total carbohydrates and glycogen on days 5 and 6 suggested the concurrent occurrence of both gluconeogenesis and glycogenesis. As the development of the embryo proceeds, both lipids and carbohydrates were utilised, resulting in the increase in the concentration of citrate, pyruvate and lactate.
