ABSTRACT:
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.
