Estimation of Protein of Silk gland of Philosamia ricini reared in two food plants Ricinus communis and Heteropanax fragrans in two seasons

Biochemical analysis of Protein content of the silk gland of Philosamia ricini reared in two food plants Ricinus communis and Heteropanax fragrans during its fourth and fifth instar. It was found that protein content was higher in the silk gland of Ricinus communis fed erisilkworm than Heteropanax fragrans.fed silkworm in the 4th instar . However in the 5th instar 5th and 6th day Heteropanax fragrans fed Philosamia ricini showed more protein content than Ricinus,communis fed ones. The protein content was higher for both food plants during spring summer than winter.
