  • Abstract:
  • The effect of Cassia tora plant extract were tested against IV and Vth instar larvae of silkworm for improving the performance of cocoon characteristic of silkworm, Bombyx mori L. The various concentration of Methanol extract of Cassia Tora plant extracts (0.5, 1.0, 1.5, 2.0 and 2.5%) were supplemented to IV and Vth instars silkworm with mulberry. The cocoon characteristic and silk performance were influenced by various concentration of plant extract. The intensity of influence was depending on the time and dose exposure. The plant extract at 2.0% concentration resulted into the improvement of cocoon and silk parameters. The mean larval growth index, pupa weight, shell weight, shell ratio, silk filament length, sericin and fibroin content of Bombyx mori were increased with this dietary supplementation of plant extract over the control. In the present study the plant extract of Cassia tora has growth promoting effect in silkworm which helps to improve the performance of cocoon and silk in Bombyx mori.
