A method for protection of a plant from damage caused by an insect pest of the order Lepidoptera and Diptera is disclosed. An insect controlling agent having an active component of an insecticidal crystal toxin produced by Bacillus thuringiensis var. kurstaki No. 145 FERM BP-3905, No. 161 FERM BP-3906, and No. 116 FERM BP-3907 is used in the method for protection of a plant. The insecticidal crystal toxin has a set of molecular weights as determined by 10% SDS-polyacrylamide gel electrophoresis of 125,000 daltons and 60,000 daltons when produced by No. 145, 130,000 daltons and 60,000 daltons when produced by No. 161, and 130,000 daltons and 60,000 daltons when produced by No. 116.
An insect pest-controlling agent comprising as an active component an insecticidal crystal toxin produced by the strain selected from the group consisting of Bacillus thuringiensis var. kurstaki No. 145 FERM BP-3905(Bt. k 145), Bacillus thuringiensis var. kurstaki No. 161 FERM BP-3906, (Bt. k 161), and Bacillus thuringiensis var. kurstaki No. 116 FERM BP-3907 (Bt. k 116), wherein the insecticidal crystal toxin has a set of molecular weights as determined by 10% SDS-polyacrylamide gel electrophoresis of about 125,000 daltons and about 60,000 daltons when produced by Bt. k 145, about 130,000 daltons and about 60,000 daltons when produced by Bt. k 161, and about 130,000 daltons and about 60,000 daltons when produced by Bt. k 116.
A method for protection of a plant from damage caused by an insect pest selected from the group of insects consisting of the order Lepidoptera and Diptera, comprising feeding the insect pest with the insecticidal crystal toxin produced by the strain Bacillus thuringiensis var. kurstaki No. 145 FERM BP-3905 (Bt. k 145), Bacillus thuringiensis var. kurstaki No. 161 FERM BP-3906, (Bt. k 161), and Bacillus thuringiensis var. kurstaki No. 116 FERM BP-3907 (Bt. k 116), wherein the insecticidal crystal toxin has a set of molecular weights as determined by 10% SDS-polyacrylamide gel electrophoresis of about 125,000 daltons and about 60,000 daltons when produced by Bt. k 145, about 130,000 daltons and about 60,000 daltons when produced by Bt. k 161, and about 130,000 daltons and about 60,000 daltons when produced by Bt. k 116.
