Abstract
The present research work were conducted to estimation of carbohydrate content in haemolymph of Multivoltine (Pure Mysore), bivoltine (CSR2) and multi-bi hybrid (PMXCSR2) of the mulberry silkworm, Bombyx mori L. were selected to estimate carbohydrate content in the haemolymph of 5^th instar larvae (day one to day six). M₅ and V1 mulberry varieties cultivated under irrigated condition was used to feed the larvae twice and four times a day. The quantification of carbohydrates was done by using spectrometer and was expressed in mg/ml of sample. The results clearly showed an increasing trend with the age of the larvae and also in batches fed four times than twice a day for both the samples. V1 contributed to higher accumulation of carbohydrates than those fed with M₅. Haemolymph exhibited higher activity while, among the breeds carbohydrate content was higher in CSR2, followed by PMXCSR2 and PM.
