ABSTRACT
Effect of nutritional conditins of silkworm, Bombyx mori on the susceptibility to Beauveria bassiana was studied and discussed in this paper. There was significant increase in the susceptibility of silkworm to B. bassiana when feed stress was imposed. Feeding with V1 variety mulberry leaves increased the susceptibility of silkworm to the fungus. Feeding silkworm with tender leaves also increased susceptibility to B. bassiana. The LT50 value was 6.18 days when tender leaves were provided and it was 6.34, 6.62 and 6.59 days with medium, matured and normal leaves, respectively. Feeding with tree mulberry leaves resulted in less mortality when compared to the others.
Key words :
Beauveria bassiana, Bombyx mori, Nutritional condition, Susceptibility.
