Abstract
The subject invention concerns a novel microbe and genes encoding novel toxin proteins with activity against cockroaches. Cockroaches are common house pests, and they create problems in hospitals, the food industry and in agriculture. The novel Bacillus thuringiensis microbe of the invention is referred to as B.t. PS185L8. The subject invention also concerns the use of B.t. PS201T6 to control cockroaches. A truncated form of a toxin obtained from PS201T6 having particular activity to cockroaches is also claimed for use in controlling the pest. The spores or crystals of the two microbes, or mutants thereof, are useful to control cockroaches in various environments. The genes of the invention can be used to transform various hosts wherein the novel toxic proteins can be expressed.
