=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.

Studies on different tree mulberry genotypes on rearing performance of silkworm (Bombyx mori L.) was carried out to identify the best performing genotypes based on the bioassay performance of silkworm cross breed PM x CSR2 during rainy, winter and summer seasons of 2018-19at the Department of Sericulture, University of Agricultural Sciences, GKVK, Bangalore. The present study comprised of six mulberry genotypes viz., MI-012, MI-79, MI-21, MI-139, MI-516, ME-05 and two check varieties V1 and M5.

Selection response for the expression of quantitative traits in the Mulberry Silkworm Bombyx mori L.
Selections for quantitative traits are paramount importance to achieve the desired breeding objectives in breed evolving programmes through hybridization. In the light of the above, an experiment was conducted utilizing six different aboriginal silkworm races namely, C108, NB4D2, Pure Mysore (PM), Nistari, zebra and knobbed belonging to two voltinistic groups by rearing them under standard laboratory conditions for six different generations during three seasons of the year.

The most important device that helps or supports the silkworm larvae for comfortable spinning of cocoons is called mountage or cocoonage and the process of transfering the mature larvae on mountage is called mounting. Even if the silkworm crop is healthy, wrong mounting methods, spinning conditions and bad type of mounting material can result in inferior or poor quality cocoons and silk yarn leading to lower income to farmers.

Different silkworm residues in combination with paddy straw were evaluated for button mushroom (Agaricus bisporus Lange) production. The substrate was prepared by substituting silk worm leaf litter, silk worm excreta and spent silk moth residue with paddy straw at 25 and 50 percents. The yield and bio-efficiency of button mushroom was found to be highest in control treatment, paddy straw (927 g per 5.00 kg substrate and 61.80%, respectively) and the yield was ranged between 890 and 760 g per 5.

Field experiments were carried out during Kharif and Rabi seasons of two years at the Department of Sericulture, Tamil Nadu Agricultural University, Coimbatore to study the influence of different pruning heights in mulberry and integrated nutrient management (INM) practices on growth, leaf and cocoon productivity as well as profitability in mulberry. The experiments were laid out in a strip plot design with three main plot treatments and six sub plot treatments replicated thrice.

The study was conducted to evaluate the performance of different fabricated mountages viz., spiral mountage, square mountage and zig-zag mountage in comparison with Thalaghattapura ribbon chandrike, plastic collapsible mountage and bamboo mountage on various cocoon reeling parameters by using two different silkworm hybrids viz., the cross breed (CB) (PM x CSR2) and the double hybrid (DH) (Krishnaraja) and data were recorded on various cocoon reeling parameters.

Antibacterial activity of six different species of fungal extracts viz., Aspergillus ochraceous, Paecilomyces variotii, Schizophyllum sp., Epicoccum sp., Metarhizium sp., Aspergillus niger were evaluated against ten serotypes of Bacillus thuringiensis to develop new bioactive secondary metabolites from the microbial sources. Fungal crude extracts were isolated by ethyl acetate solvent extraction method and product yields varied from 0.150g to 0.538g. Thin Layer Chromatography was carried out for detecting the small molecule compounds present in the crude extracts.

Feeding is the most important factor in silkworm rearing, as it has a direct impact on growth and development of worms. Silkworm requires feed five times a day at an interval of five hours. However, the rearers of J&K state feed the worms two times only, resulting in lower cocoon yield. Feeding of quality mulberry leaves has a great impact on biology and physiology of silkworm Bombyx mori L. The study revealed 3 feedings per day was statistically at par with 4 feedings in terms of various parameters including larval survival percentage i.e. 93.50 ± 0.76 for 3 feedings and 95.00 ± 0.

The gamma radiation was given to 4 day and 8 day old pupae of uzi flies at two effective doses of 1.5 and 2 kr and the observations were recorded for two generations and the study was carried out in the department of Sericulture, UAS, GKVK, Bengaluru. The pre-mating duration was significantly different between 1.5 and 2 kr when 4 day old pupae and 8 day old pupae were irradiated, the mating duration was not significantly different between 1.5 and 2 kr when 4 day old pupae and 8 day old pupae were irradiated. The ovipositional duration showed a significant difference between 1.

The present investigation was carried out at Central Sericultural Research and Training Institute, Pampore, Jammu & Kashmir (J&K) during spring, summer and autumn, 2018 to study the performance of 24 bivoltine silkworm, Bombyx mori L, foundation crosses (12 Oval & 12 Constricted) under temperate climatic conditions. The rearing was carried out under uniformed laboratory condition by adopting standard method. These 24 bivoltine silkworm foundation crosses (FC) were evaluated for their performance in eight metric traits viz., fecundity (No.

Four different concentrations (10.0 ppm; 20.0 ppm; 40.0 ppm and 50.0 ppm) of the aqueous solution of seed powder of Syzigium cumini (L) concentrations was used to treat the leaves of mulberry and fed to the fifth instar larvae of bivoltine, crossbreed silkworm, Bombyx mori (L) Race: Bivoltine Cross Breed [(CSR6 x CSR26) x CSR2 x CSR27)] for first four days of fifth instar larvae. The larvae fed with untreated and water treated leaves were also maintained. The midgut enzyme (protease and amylase) bioassays were carried out on fifth day.
