摘要
The invention is related to a biologically pure Bacillus thuringiensis (B.t.)strain active against lepidopteran and coleopteran pests which produces a bipyramidal crystal consisting essentially of a delta-endotoxin 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 obstainable therefrom. The invention further relates to methods of using the insecticidal compositions to control insect pest from the order Lepidoptera and/or Coleoptera. The invention also relates to isolated DNA sequences encoding the delta-endotoxins. IMAGE
