Abstract
The subject disclosure concerns Bacillus thuringiensis strains which can be used to control lepidopteran pests. The strains were previously known to control coleopteran pests. The discovery of lepidopteran activity was totally unexpected. These B.t. strains can be formulated using standard lepidopteran formulation procedures. Means of administration are also standard. The genes encoding lepidopteran-active toxins can be isolated from the B.t. isolates and used to transform other microbes or plants for use to control lepidopteran pests.
Claims20
A method for controlling lepidopteran insect pests which comprises contacting said insect pests with an insect-controlling effective amount of a Bacillus thuringiensis isolate selected from the group consisting of B.t. PS43F, B.t. PS50C and B.t. PS86A1, and variants thereof.
A method for controlling lepidopteran pests which comprises exposing said pests to a plant transformed by a gene obtainable from a Bacillus thuringiensis isolate selected from the group consisting of B.t. PS43F, B.t. PS50C and B.t. PS86A1, and variants thereof, wherein said gene encodes a toxin active against lepidopteran pests.
A method for controlling lepidopteran insects which comprises administering to said insects or to the environment of said insects a microorganism transformed to express a Bacillus thuringiensis toxin active against lepidopteran pests encoded by DNA selected from the group consisting of SEQ ID NO. 1, SEQ ID NO. 3. SEQ ID NO. 5, and any fragments of those sequences sufficient to encode a lepidopteran-active toxin.
