Abstract:
The experiment was conducted in the Entomology Laboratory of Barrister Thakur Chhedilal College of Agriculture and Research Station, Bilaspur (Chhattisgarh), during September-October, 2021 in Completely Randomized Design with nine treatments and three replications. Larvae of Silkworm hybrid MYX × CSR₂ were fed on mulberry varieties CMY-1, C-2038, CPP-1, S-1635, CPP-1, V-1, S-13, K-2, and mixture of all varieties leaf. Observations on the dimensions of different instars of silkworm Bombyx mori L. were recorded. Mulberry variety S-1635 was recorded as best variety for growth and development of silkworm during final instars with maximum larval length (68.83 mm), larvae breadth (9.93 mm) and larval weight (3.20 g). Variety V-1 was also observed promising so far growth and development of silkworm larvae is concerned, while minimum larval length, breadth and weight was observed when larvae fed on mixture of all varieties.
