Abstract:

The principle of efficient use of available system for quality improvement is tried to utilize in the present study. The present attempt was undertaken to study the influence of acetone solution of Ferruginol, a natural phenol and a meroterpene compound, on the cocoon characters and silk filament parameters of silk worm Bombyx mori (L.) (Race: PM x CSR2). Three concentrations (5ppm; 10ppm and 20ppm) of Ferruginol were prepared. The fifth instar larvae were utilized for the experimentation. Soon after the fourth moult, the fifth instar larvae were grouped into five groups (each with hundred individuals) (Untreated control; Acetone treated control; 5ppm Ferruginol; 10ppm Ferruginol and 20ppm Ferruginol). Ten microliters of each concentration of Ferruginol solution were topically applied to respective group to the individual larva at 48 hours after the fourth moult. The larvae were maintained through standard schedule. Acetone solution of Ferruginol at 5 ppm, 10 ppm and 20 ppm concentrations recorded maximum cocoon weight (2.046; 2.387; 2.924gm), shell weight (0.438, 0.541, 0.673 gm), pupal weight (1.613; 1.846; 2.252 gm). All three concentrations of Ferruginol recorded significant weight of cocoon, shell, and pupal weight in comparison with the control (untreated and acetone treated).There was a gradual increase in the silk yield with an increase in the concentrations of Ferruginol (in acetone) from 5 ppm, 10 ppm and 20 ppm. Shell ratio of the cocoons harvested from the treated group were found with most significant (** P < 0.005, ***P < 0.01) influence. Similar type of effect was observed for the silk filament parameters. Efficient use of acetone solution of Ferruginol may open a new avenue in the field of sericulture.
