Variations in the total sterols, free sterols and sterol esters concentration during embryogenesis in Dysdercus similis (Freeman).
In the present study fluctuations in the total sterols, free sterols and sterols esters concentration has been recorded day to day during embryogenesis. Oscillations in the total sterol correlated with the biosynthesis and/or utilization of cholesterol occur in the eggs while free sterols are used in the maintenance of cell membranes. The role of sterol ester is not known but their increase may be correlated with the accretion of oleic and linoleic fatty acids.
