Changes in the Titer of Protein and Cholesterol Content in Non-Diapause, Artificially Diapause Terminated and Diapause Eggs of Silkworm, Bombyx mori.

A differential specific pattern of variation in the metabolism of protein and cholesterol was noticed in non-diapause and diapause eggs due to the significant differences in embryonic development. The rate of metabolism was different due to specific demands of such metabolites during active embryogenesis and maintenance of diapause respectively. In general, the metabolic rate was found to be accelerated in non- dia-pause eggs just after egg deposition, while it was very slow in diapause eggs. When the diapause eggs were treated with hydrochloric acid within 16-20 hrs, the rate of turnover was found to very similar to non- dia-pause eggs, though the base level of protein and cho-lesterol was recorded to be different.
