To assess food intake and utilization efficiency in B. mori reared at different temperature combinations, larvae of Pure Mysore race were fed ad libitum on M5 mulberry leaves and reared at four different constant temperatures, viz. The important reasons for low production are attributed to traditional method of silkworm rearing on tall trees in natural habitat, which exposes the larvae to a number of predators, parasites and diseases apart from natural vagaries.
