Abstract

The suitable and appropriate environmental conditions and also the mulberry leaves with high nutritional content for feeding is the key for the success of sericulture industry.The rearing of silkworms for getting better yield of raw silk there is need to study the environmental impact on the enzyme activities which will directly affect the food consumption and utilization. Hence, in the present study the impact of seasons viz summer, winter, and rainy on Amylase and Invertase activity from the midgut,fatbodies,haemolymph and silkgland of silkworm Bombyxmori L. was analysed. A comparative study was done by feeding the larvae with two different varieties of mulberry viz V1 and M5. Among the seasons,insummer,significant increase in the amylase activityobserved in all test tissues whilein winter invertase activity increasedin all test tissues of silkworm larvae fed on both V1 and M5 mulberry leaves.
