Abstract
Histopathological studies were conducted on the larvae of the cotton leafworm, Spodoptera littoralis (Boisd.) using the commercial product Profect® (a mixture of Bacillus thuringiensis var. kurstaki and S. littoralis NPV). Treatment of the 4th instar larvae with the bioinsecticide revealed many ultrastructural alterations in the midgut of the 6th instar larva. This mixture formula proved to be effective against the midgut epithelial cells and induced the marker of cell death. Accordingly, utilization of this biocontrol agent for controlling the cotton leafworm provides a promising alternative to conventional insecticides.
