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.

Bacillus thuringiensis cultures deposited as NRRL B-18747, NRRL B-18749 and NRRL B-18750 have dipteran activity. Thus, these cultures, or mutants thereof, can be used to control such insect pests. Further, genes encoding novel .delta.-endotoxins can be removed from these cultures 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 invention concerns novel isolates of Bacillus thuringiensis (B.t.) which contain a toxin(s) which is active against nematodes. This B.t. toxin(s) or B.t. isolate(s) can be used to treat animals and plants hosting susceptible nematodes.

The subject invention concerns novel materials and methods for the control of cockroaches. Cockroaches are common house pests, and they create problems in hospitals, the food industry and in agriculture. According to the subject invention, activated toxins of Bacillus thuringiensis var. israelensis (B.t.i.) are used to control cockroaches. In one embodiment, the subject invention also concerns the use of B.t. PS123D1 to control cockroaches. A truncated form of a toxin obtained from PS123D1 having particular activity to cockroaches is also claimed for use in controlling the pest.
摘要:
The subject invention concerns a novel microbe and gene encoding a novel toxin protein with activity against insect pests of the order Coleoptera. Pests in the order Coleoptera do heavy damage to crops, e.g., corn. The novel Bacillus thuringiensis microbe of the invention is referred to as B.t. PS50C. The spores or crystals of this microbe, or mutants thereof, are useful to control coleopteran pests in various environments. The novel gene of the invention can be used to transform various hosts wherein the novel toxic protein can be expressed.
摘要:
Certain known and available strains of Bacillus thuringiensis (B.t.) have been found to have activity against coleopteran pests. Previously, these strains were not known to have any insecticidal properties. The B.t. strains can be used in various environments to control coleopteran pests, e.g., the Colorado Potato Beetle.
摘要:
Nematicidal .delta.-endotoxin encoding genes have been cloned from a novel Bacillus thuringiensis isolate known as B.t. PS17. These novel genes, designated B.t. PS17a, B.t. PS17b, Bt. PS17d, and B.t. PS17e, can be transferred to various microbial and plant hosts via known techniques. In the microbial or plant host, one or more of the genes of the invention can be used to express the novel nematicidal toxins to control susceptible nematodes.

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.
