  • EVALUATION OF NEW BIVOLTINE SILK WORM DOUBLE HYBRIDS TOLERANT TO HIGH TEMPERATURE AND MUSCARDINE DISEASE IN EASTERN DRY ZONE OF KARNATAKA
    Nikita Kankanawadi, Manjunath Gowda, K C Narayanaswamy, K H Nagaraj
    Indian Journal of Entomology, 2026
    Field evaluation of double hybrids of high temperature and muscardine disease tolerant silkworm breeds viz., (B1× B2) × FC1, (B1 x B4) x FC1 and FC2 x (B6 x B8) was carried out in fifteen farmers field, covering Tumakuru and Chikkaballapura districts. The statistical analysis of data was done through Completely Randomised Design with 15 replications of each double hybrid and its control. The results have shown that (B1 x B4) x FC1 double hybrid was superior for ten out of thirteen traits viz. fecundity (587.86 eggs/ dfl), hatching (98.37 %), dead eggs (1.39 %), fifth instar larval weight (47.23 %), effective rate of rearing (97.27 %), cocoon yield by number (8813.43/ 10,000 larvae), cocoon yield by weight (19.77/ 10,000 larvae), single cocoon weight (2.35 g), shell weight (0.46 g) and shell ratio (21.70 %), while (B1x B2) x FC1 for four traits viz. hatching, dead eggs and total larval duration and cocoon yield by weight compared to control commercial double hybrid FC2 × FC1, marking their dual tolerance advantageous to sericulture industry.

    Journal of Biological Control, 2025
    The present research work was carried out to know the efficacy of the silkworm pupal chitosan against the bacterial pathogens of silkworm Bombyx mori L. under in-vitro conditions. Chitosan was isolated from silkworm pupae and their exuviae through a meticulous three stage extraction process viz., deproteinisation, demineralisation and deacetylation. The extracted chitosan, prepared in various concentrations (i.e., 500-5000 ppm), was rigorously evaluated against the pathogenic bacteria of B. mori (Staphylococcus aureus and Bacillus thuringiensis) under in-vitro conditions. These tests were conducted using nutrient agar plates, with the efficacy of each concentration benchmarked against standard ampicillin and a commercial chitosan preparation by assessing their inhibitory effect through measuring the inhibition zones around treated discs. The antibacterial activity increased with chitosan concentration, with the highest zone of inhibition observed at 5000 ppm (1.191 cm for S. aureus and 1.100 cm for B. thuringiensis), which was on par with the treatment ampicillin and commercial chitosan at 1000 ppm. Concentrations ≥2000 ppm showed antibacterial efficacy comparable to standards at 1000 ppm. The antimicrobial action is attributed to the interaction between positively charged amino groups of chitosan and bacterial teichoic acids, resulting in cell wall rupture and death of bacteria. The in-vitro study reveals that, silkworm pupal chitosan exerts potent antibacterial activity against S. aureus and B. thuringiensis, particularly at ≥4,500 ppm. This valorises a sericultural by-product, offering a sustainable alternative to synthetic bactericides. The findings hold promise for enhancing silkworm health management and optimising sericulture productivity.

  • Rural Bio-Resource Complex: A Holistic Approach to Improve Livelihood Security of Farmers
    K. Narayana Gowda, K.C. Narayanaswamy
    Basics of Human Civilization Food Agriculture and Humanity Volume I Present Scenario, 2021
    In the recent past livelihood support systems linked to agricultural sector have degraded and in.certain situation assumed declining trends. It has been cause for distress in rural families resulting larger migration in search of livelihood. In view of this fact, a conceptual project was visualized as Rural Bio-Resource Complex (RBRC) to rejuvenate the livelihood support system through inter-disciplinary approach. The RBRC Project with the financial assistance of DBT-GOI was implemented in Bangalore Rural District of Karnataka State by the University of Agricultural Sciences, Bangalore for a period of five years from 2005. The project was implemented on consortium approach involving 268interdisciplinary team and related organizations to increase the income and living standards of stakeholder farmers including landless families by rebuilding the confidence by demonstrating farming as a livelihood security as well as profitable venture. The project considered six factors to enhance the income and standard of living of farm and non-farm families by addressing end-to end issues. In a span of five years, the project activities were able to bring about significant impact in terms of shift in cropping pattern, added net income, employment generation and improved socio-economic status of the stakeholders. The awards in recognition of the achievements to farmers have acted as motivation and also derive satisfaction in their vocations. An overall assessment indicated that project model was able to realize 11 per cent growth rate in agricultural activities and improvement in applied livelihood systems. The model is being replicated in North Eastern States of India and the Integrated Farming System (IFS) validated in this project is being replicated in all the districts of Karnataka state with the financial assistance from Government of Karnataka under Rashtriya Krishi Vikasa Yojane. The project model has promise for replication in agricultural landscapes to sustain the livelihood systems and also realize progressive growth in agriculture sector at regional to country level.
