Abstract
The subject invention concerns novel Bacillus thuringiensis strains containing parasporal proteins with pesticidal properties against whitefly, aphid, jassid, and possibly other sucking insects of agronomic importance, and peptide sequences to these proteins that can be used to obtain structural genes. The spores or crystals of these microbes, or mutants thereof, are useful to control hymenopteran pests in various environments. The genes of the invention can be used to transform various hosts wherein the novel toxic proteins can be expressed.
Claims5
A method for controlling pests from the family Aphididae which comprises contacting said pests with an aphid-controlling amount of a Bacillus thuringiensis isolate selected from the group consisting of Bt CAMB 786, Bt CAMB 787, Bt CAMB 788, Bt CAMB 3616, and Bt CAMB 3667, and variants thereof, or toxic crystals or spores of said isolates.
A composition of matter comprising Bacillus thuringiensis selected from any one of the group consisting of Bt CAMB 786, Bt CAMB 787, Bt CAMB 788, Bt CAMB 3616, and Bt CAMB 3667 or mutants thereof, or spores or crystals of any one of said Bt in association with an insecticide carrier.
A biologically pure culture of Bacillus thuringiensis selected from the group consisting of Bt CAMB 786, Bt CAMB 787, Bt CAMB 788, Bt CAMB 3616, and Bt CAMB 3667, and variants thereof.
A toxin that is active against hymenopteran pests and that is producible by a Bacillus thuringiensis selected from the group consisting of Bt CAMB 786, Bt CAMB 787, Bt CAMB 788, Bt CAMB 3616, and Bt CAMB 3667, and variants thereof.
