Abstract
Disclosed and claimed are toxins produced by novel Bacillus thuringiensis isolates designated B.t. PS92J, B.t. PS196S1, B.t. PS201L1, and B.t. PS201T6, which have dipteran and/or corn rootworm activity. Thus, the isolates, or mutants thereof, can be used to control such pests. Further, claimed are novel genes encoding these .delta.-endotoxins, which can be expressed in other hosts. Expression of the .delta.-endotoxins in such hosts results in the control of susceptible insect pests in the environment of such hosts.
Claims2
A recombinant or purified toxin which is active against dipteran pests, wherein said toxin has an amino acid sequence that is at least about 90% homologons with the amino acid sequence shown in SEQ ID NO. 7.
