Abstract

The investigation mainly focused to examine the mutilation caused by the fungal pathogen Beauveria bassiana during its growth and development in 5th instar silkworm larvae using histopathological indices. Day to day histopathological analysis of three regions of silkgland i.e., anterior, middle and posterior regions during the development of fungal pathogen in fifth instar silkworm larvae revealed no significant changes in the first two days of the post inoculation. On the third day of the instar mycelia of Beauveria bassiana was noticed in the unica propria the outermost layer of the silk gland and on the 4th an 5th day of inoculation, secretory cells in the glandular layer filled with mycelia. Shrinkage of silkgland tissue and vacuoles was observed on 6th and 7th day of post - inoculation of Beauveria bassiana. The histopathological study revealed extensive hyphal growth with a subsequent melanization and shrinkage of the tissue in the silkgland.
