Abstrakt: An isolate of Bacillus thuringiensis has been identified with toxic activity against coleopteran insects but not against lepidopteran or dipteran species. Toxin crystals from this strain contain a polypeptide of approximately 64,000 molecular weight possessing insecticidal activity. This toxin differs in polypeptide composition from other reported Bacillus thuringiensis toxins and does not appear to be processed from a larger precursor form. Insecticidal activity against the Colorado potato beetle and the boll weevil suggests the possibility of commercial applications of this strain.
