The quantum of food, rearing bed area required/40,000 larvae of two new races viz. CSR2 x CSR5 and BL24 x NB4D2 were evaluated and an improved rearing package was prepared. Field trials were conducted to evaluate the adaptability of the package. Results revealed that by giving 20% more food and bed area the cocoon yield could be increased by 5-7 kg/40,000 larvae in both the races. Comparative economics of the present and improved rearing packages also showed a net gain of Rs. 1233.45/- and Rs. 649.75/- for 40,000 larvae of CSR2 x CSR5 and BL24 x NB4D2 respectively.
