Abstract
This invention relates to Bacillus thuringiensis strains that have insecticidal activity against lepidopteran and coleopteran insects, the coleopteran-active endotoxin being produced by an acquired plasmid. This invention also relates to the crystalline protein toxin useful as a biological insecticide against Coleoptera which toxin is produced by the strain of Bacillus thuringiensis. This invention also relates to the expression in various microorganisms of the gene, known as cryC, which codes for this toxin, and for related novel insecticide compositions and methods for their use.
