Abstract:
Studies on pathogenicity and development of Bacillus thuringiensis in termites, Microcerotermes championi and Bifiditermes, beesoni, were carried out. Both the termites were found susceptible to the infection caused by B. thuringiensis. Histopathological studies showed that B. thuringiensis developed earlier in M. championi as compared to B. beesoni. In M. championi, the bacterial rods attacked midgut villi after 6 hours, reached the body cavity and attacked fat body and hypodermal cells within 20-24 hours following infection. In the case of B. beesoni, the bacterial rods reached near the peritrophic membrane after 24 hours, attacked epithelial and regenerative cells after 48 hours and reached the basement membrane of the midgut 72 hours after infection.
