Summary

Laboratory studies were conducted to evaluate the pathogenic effect of Dipel Bacillus thuringiensis separately, and in combination with sugar on the fourth instar larvae of spiny bollworm using both a dipping and a residue film method of application. In addition the histopathological changes in the treated mid-gut larvae are described.
