ALTERATIONS IN NITROGENOUS ENDPRODUCTS OF LITTER OF V INSTAR SILKWORM LARVAE, BOMBYX MORI (L) ON TREATMENT WITH XHYROXINE HORMONE

摘要

In the present investigation an attempt was made to find out the impact of thyroxine on nitrogenous end products in the litter of V instar silkworm larvae, Bombyx mori (L). The hormone treated mulberry leaves were fed to silkworm larvae from 1st day of III instar to 5th day of V instar. The nitrogenous end products of litter such as ammonia, urea, uric acid, glutamine, urea/ammonia and glutamine/ammonia ratios were analysed. The ammonia, urea, and urea/ammonia ratio recorded significant elevation where as glutamine, uric acid and glutamine/ ammonia ratios were decreased over control. The present study indicates the significant influence of thyroxine hormone on nitrogenous end products of litter in silkworm larvae.
