Performance of Six Eco Races of Samia ricini Donovan Reared during Summer Season

Rajani Kant Manoj, Dr. Bhrigu Nath

Abstract: The impact of summer season on ten parameters such as fecundity, hatchability, larval duration, larval mortality, life cycle duration, ERR, weight of larva, cocoon and shell as well as shell ratio were observed for six eco races (Strains) of Samia ricini such as Greenish Blue Plain (GBP), Greenish Blue Spotted (GBS), Greenish Blue Zebra (GBZ), Yellow Plain (YP), Yellow Spotted (YS) and Yellow Zebra (YZ). On the basis of overall performance, it became evident that summer season remains suitable for rearing of GBS strain as compared to other strains of Samia ricini examined during present research work. Thus, rearing of GBS strain of Samia ricini is recommended for sub - tropical regions of India for better productivity.
