    摘要： The invention relates to a mutant of Bacillus thuringiensis which produces a larger amount of crystal delta-endotoxin with a greater pesticidal activity as compared to the corresponding parental strain. The mutant may also have a larger crystal size as compared to the corresponding parental strain. The crystal delta-endotoxin produced by the mutant Bacillus thuringiensis will have an activity directed towards the same pest(s) as its parental Bacillus thuringiensis crystal delta-endotoxin. The invention further relates to a method for producing such a mutant, compositions comprising such a mutant as well as methods for controlling a pest(s) using these compositions.

    摘要： Disclosed and claimed is a novel Bacillus thuringiensis isolate designated B.t. PS192N1 which has dipteran activity. 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.

    摘要： The subject invention concerns novel microbes and genes encoding novel toxin proteins with activity against insect pests of the order Hymenoptera. Pests in the order Hymenoptera are common house pests, and they create problems in hospitals, the food industry and in agriculture. The novel Bacillus thuringiensis microbes of the invention are referred to as B.t. PS140E2 and B.t. PS86Q3. The spores or crystals of these microbes, or mutants thereof, are useful to control hymenopteran pests in various environments. The genes of the invention can be used to transform various hosts wherein the novel toxic proteins can be expressed.

    摘要： The subject invention concerns Bacillus thuringiensis microbes with activity against select coleopteran pests e.g., Diabrotica sp., Hypera sp., and various flea beetles. For example, the B.t. isolates of the invention are active against alfalfa weevils (AW, Hypera brunneipennis), rape flea beetles (RFB, Phyllotreta cruciferae), and corn rootworms (CRW, Diabrotica undecimpunctata undecimpunctata). Thus, these microbes can be used to control these pests. Further, genes encoding toxins active against these pests can be isolated from the B.t. isolates and used to transform other microbes. The transformed microbes then can be used to control susceptible coleopteran pests.
