Novel bacillus thuringiensis isolates active against dipteran pests.

摘要

Disclosed and claimed are novel Bacillus thuringiensis isolates designated B.t. PS192N1, B.t. PS92J, B.t. PS196S1, B.t. PS201L1, and B.t. PS201T6, which have dipteran activity. Thus, these isolates, or mutants thereof can be used to control such insect pests. Further, genes encoding novel delta -endotoxins can be removed from these isolates and transferred to other host microbes, or plants. Expression of the delta -endotoxins in such hosts results in the control of susceptible insect pests in the environment of such hosts.
