Improvement of high yielding, disease resistant silkworm strains became imminent to increase production of silk, which is a major revenue earner for sericulturists. Since environment interacts with phenotype, conventional breeding did not result in commendable yield improvement in synthetic strains of silkworm, Bombyx mori. Identification of DNA markers associated with different economically im...
The effect of ascorbic acid and lemon juice on the silkworm, Bombyx mori has been studied with reference to larval growth, protein synthesis and silk production. Both these exogenous factors, when supplemented with mulberry diet, showed positive impact on larval growth during the fourth and fifth instar developmental stages. The analysis of growth trends in terms of compound periodical growth r...
Fluorophores are ubiquitous in nature. Naturally occurring fluorophores are exceptionally stable and have high quantum yield. Several natural systems have acquired fluorescent signature due to the presence of these fluorophores. Systematic attempt to harvest these fluorophores from natural systems could reap rich commercial benefit to bio-imaging industry. Silk cocoon biomaterial is one such ex...
Three quercetin glycosides, quercetin 5-O-beta-D-glucoside, quercetin 7-O-beta-D-glucoside, and quercetin 4'-O-beta-D-glucoside, and two kaempferol glycosides, kaempferol 5-O-beta-D-glucoside and kaempferol 7-O-beta-D-glucoside, along with their aglycones, quercetin and kaempferol, were isolated from an ethanolic extract of Sasamayu cocoon shells. The chemical structures were characterized by c...
The experiment was carried out during 2019-20 at P-2 Pure Mysore Multivoltine Basic Seed Farm (BSF), National Silkworm Organisation, Nagenahalli, Karnataka to know the effect of nutrient management on growth and yield G4 mulberry variety its subsequent bioassay multivoltine silkworm, Mysore. garden (three years old) with planted in paired row system used for seven treatments three replications....
Silkworm Bombyx mori is an important economic insect and also a tool to convert leaf protein into silk. The industrial and commercial use of silk, the historical and economic importance of production and its application in all over the world finely contributed to the silkworm promotion as a powerful laboratory model for the basic research in biology. The mulberry leaf is the only important sour...
Samia cynthia ricini Boisduval Lepidoptera:Saturniidae is a lepidopteran insect that has gregarious behaviour during their larval stage. This research aimed to determine the minimum population limit of larvae can support survival S. c. by observing development time, fecundity, and hatchability eggs produced adult moths under different densities rearing conditions. The was conducted lifecycle at...
Human serum albumin (HSA) is an important biological preparation with a variety of biological functions in clinical applications. In this study, the mRNA of a fusion transposase derived from the pESNT-PBase plasmid and a pBHSA plasmid containing the HSA gene under the control of a fibroin light chain (FL) promoter were co-injected into fertilized eggs. Fifty-six transgenic silkworm pedigrees ex...
Mulberry silkworm, Bombyx mori L, most valued for silk and other medicinal products is prone to various biotic stresses among which the disease caused by Nuclear Polyhedrosis Virus (BmNPV) is most serious as it occurs throughout the year causing losses to the tune of 30-40 per cent. Studies conducted on eco friendly management of the disease using botanicals revealed that 800 ppm hexane leaf ex...
an experiment was conducted to study the effect on performance of silkworm bombyx mori l., when fed by leaves of different mulberry varieties a crd design with 12 tratments (including kamasari, kaeiryo ichinose, kaeerizhotezomigaeeshi, tachibana, ichinose, chekemaoha, yukishinogi, shin ichinose, wasemidori, roso, kenmochi, as well as some local varieties in 4 replications. the larvae were reare...
