The invention relates to a method for producing an integrant(s) of Bacillus thuringiensis which produces a larger quantity of a crystal delta-endotoxin greater pesticidal activity as compared to the crystal delta-endotoxin produced by the corresponding parental strain. The crystal delta-endotoxin produced by the integrant Bacillus thuringiensis will have an activity directed towards the same pest(s) as its parent Bacillus thuringiensis crystal delta-endotoxin. The invention further relates to such integrants, compositions comprising such integrants, as well as methods for controlling a pest(s) using these compositions.
