Author(s): BN Prashanth Kumar, RS Umakanth
Abstract: The present study 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 fat body of 5th 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/g 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. Fat body exhibited higher activity while, among the breeds carbohydrate content was higher in CSR2, followed by PMXCSR2 and PM for both the samples used for the present investigation.
