NEW STRAIN OF BACILLUS THURINGIENSIS

摘要

A novel Bacillus thuringiensis strain which produces crystal proteins during sporulation that are toxic to Lepidoptera. The crystal proteins comprise 130 kDa and 135 kDa protoxins which can yield 60 and 63 kDa toxins, respectively, as trypsin-digestion products. The strain, itself, or its crystals or its mixtures of protoxins or toxins can be used as the active ingredient in an insecticidal composition for combatting Lepidoptera.
