The invention is related to a novel biologically pure Bacillus thuringiensis (B.t.) strains active against lepidopteran and coleopteran pests which produces a bipyramidal crystal consisting essentially of at least two delta-endotoxins having a molecular weight of about 130,000 daltons and a rhomboidal crystal consisting essentially of two delta-endotoxins, each having a molecular weight of about 33,000 daltons, as well as spores, crystals, delta-endotoxins and/or mutants thereof. The invention also relates to insecticidal compositions obtainable therefrom. The invention further relates to methods of using the insecticidal compositions to control an insect pest(s) from the order Lepidoptera and/or Coleoptera. The invention also relates to isolated DNA sequences encoding the delta-endotoxins.

The invention is related to a novel strain(s) of Bacillus thuringiensis in which essentially all of the pesticidal activity of said strain is in the supernatant of a fermentation of said strain. The strain produces a substance which has activity against an insect pest(s) of the order Coleoptera and which enhances the pesticidal activity of a Bacillus related pesticide. The invention further relates to pesticidal compositions comprising the substance and a pesticidal carrier, or the substance and a Bacillus related pesticide, a chemical pesticide and/or a virus with pesticidal properties as well as methods of using the pesticidal compositions to control a pest.
