BIOLOGICALLY ACTIVE BACILLUS THURINGIENSIS ISOLATES AND GENEENCODING A COLEOPTERAN-ACTIVE TOXIN

摘要

MA71-C Disclosed and claimed are Bacillus thuringiensis isolates designated B.t. PS86A1 and B.t. PS86Q3, which are active against corn rootworm larvae and the alfalfa weevil. Thus, these isolates, or mutants thereof, can be used to controlsuch pests. Further, genes encoding novel .delta.-endotoxins can be removed fromthese isolates and transferred to other host microbes, or plants. Expression of the .delta.-endotoxins in such hosts results in the control of susceptible coleopteran insects.
