Abstract:

Three types of artificial diets viz., Artificial diet1, Artificial diet2 and Artificial diet3 with different compositions were used for rearing Kolar Gold race of mulberry silkworm, Bombyx mori L. where the diets were fed up to initial three instars and the later two instars were reared on natural diet (untreated leaves). Formulated diets were compared with natural diet and the observations on growth parameters were recorded. The study revealed that amongst the three formulated artificial diets, artificial diet1 (mulberry leaf powder - 30 g, soybean powder - 28 g, cellulose powder - 15 g, corn starch -6 g, citrate - 3.5 g, salt mixture - 4 g, sucrose - 4 g, agar agar - 7 g, along with vitamin B mixture - 0.40 g, soybean oil - 1.30 g and antibiotic chloramphenicol - 1.00 g and water - 302.0 ml) was found to be promising in almost all the growth parameters of the silkworm under study and selected for further studies. Growth parameters like larval weight and larval length were significantly maximum in silkworms which were fed with artificial diet1, followed by artificial diet3. Larval weight and larval length was maximum in artificial diet1 with 4.338 g and 7.25 cm respectively, followed by artificial diet3 with 4.213 g and 7.00 cm respectively in final instar. In artificial diet1, larval duration was extended by 83 hr followed by artificial diet3 in which larval duration was prolonged by 94 hr in comparison with natural diet,. In artificial diet1, moulting period was curtailed by 3 hr. However, in artificial diet3 it was extended by 20 hr in comparison with natural diet. In all the instars flacherie disease occurrence was meager in artificial diet1 with 0.75 per cent, followed by artificial diet3 with 1.00 per cent in initial instar and in later instars, disease occurrence was minimum in artificial diet1 with 2.53 per cent followed by artificial diet3 with 2.55 per cent.
