Disclosed and claimed is a novel Bacillus thuringiensis isolate designated B.t. NRRL B-18721 which has activity against dipteran insect pests. Thus, this isolate, or mutants thereof, can be used to control such insect pests. Further, genes encoding novel (delta)-endotoxins can be removed from the isolate 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.
