Studies on nutritional effects of Arthrospira platensis and Saccharomyces cerevisiae supplementation with silver nanoparticles on growth and economic traits of Silkworm, Bombyx mori L.

In the present study, the growth rate of larvae and cocoon of silkworm Bombyx mori fed with silver nanoparticles (AgNps) treated MR2 mulberry leaves was studied. The different concentrations (10, 20 and 30%) of prepared silver nanoparticles were given to the larvae. The Average cocoon weight was found highest in 30% concentration T3 and (0.423 ± 0.012 g) and T6 (0.583 ± 0.051 g) over the control (0.316 ± 0.041 g) respectively. The pupal weight of B. mori was found to be highest with 30% AgNps treatment of Arthrospira platensis and Saccharomyces cerevisiae were T3 (0.213 ± 0.026 g) and T6 (0.353 ± 0.083 g) compared to control (0.16 ± 0.016). The AgNps treated larvae showed maximum shell weight in T3 (0.753 ± 0.29 g) and T6 (0.843 ± 0.37 g), fibroin content in T3 (82.099%) and T6 (83,44%) and sericin content in T3 (17.90%) and T6 (916.55%) was observed and provides a good reliability. The treatments T3 (777 ± 103.9434 m), and T6 (766.666 ± 51.096 m) showed maximum filament length as compared to control. The influence of mulberry leaves enriched with Ag Nps of spirulina and yeast exhibited their highest single silk filament weight, T3 (0.21 ± 0.029 g) and T6 (0.23 ± 0.0374 g) respectively, when compared to control (0.15666 ± 0.0262 g).
