A method for potentiating the insecticidal activity of a protein toxin of Bacillus thuringiensis bacteria is disclosed. A potentiating amount of trypsin inhibitor is co-administered to the insect along with the B.t. toxin. Improved insecticidal compositions are also disclosed which contain an insecticidal amount of a protein toxin of Bacillus thuringiensis and a potentiating amount of a trypsin inhibitor.
