Abstract

The entomopathogenic fungal parasites are causing the muscardine disease in larval instars of silkworm, Bombyx mori (L). The muscardine disease in the larval instars of silkworm is  caused by fungus, Beauveria bassiana (Bals) Vuill. The  Beauveria bassiana (Bals) Vuill is one of the most destructive pathogen of silkworm Bombyx mori L and it is common in all sericulture zones of the world. The fungal disease is common during winter and rainy seasons. White muscardine was the first disease described in insects caused by a microorganism. This fungus was named eventually Beauveria bassiana in  honor of Agostino Bassi, sometimes called de Lodi (25 September 1773 – 8 February 1856), Italian entomologist, botanist and bacteriologist recognized as the “Father of Insect Pathology”.  Beauveria bassiana infection influenced the growth and development of silkworm larvae and ultimately the economical cocoon characters like matured larval weight, cocoon weight, shell weight, shell percentage, filament length, non-breakable filament length, number of breaks and denier. Significant reduction of matured larval weight (2.08 g), cocoon weight (0.72 g), shell weight (0.09 g), shell ratio (12.80%), filament length (478.9 m), non-breakable filament length (120.8 m) and more number of breaks (4.1) and higher denier (2.62 d) was recorded in the experimental silkworm compared to control.
