Oxidative Damaged Products, Level of Hydrogen Peroxide, and Antioxidant Protection in Diapausing Pupa of Tasar Silk Worm, Antheraea mylitta: A Comparative Study in Two Voltine Groups.

The present study demonstrates tissue-specific (hemolymph and fat body) and inter-voltine [bivoltine (BV) and trivoltine (TV)] differences in oxidatively damaged products, H2O2 content, and the relative level of antioxidant protection in the diapausing pupae of Antheraea mylitta. Results suggest that fat body (FB) of both the voltine groups has oxidative predominance, as evident from the high value of lipid peroxidation and H2O2 content, despite better enzymatic defenses in comparison to hemolymph (HL). This may be attributed to the higher metabolic rate of the tissue concerned, concomitant with high lipid content and abundance of polyunsaturated fatty acids (PUFA).
