摘要:
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.

The subject invention concerns Bacillus thuringiensis isolates designated B.t. PS157C1, B.t. PS86A1, and B.t. PS75J1, which are active against aphid pests. Thus, these isolates, or variants thereof, can be used to control such 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 microbe hosts results in the control of aphid pests, whereas transformed plants become resistant to aphid pests.

This invention concerns genes or gene fragments which have been cloned from novel Bacillus thuringiensis isolates which have nematicidal activity. These genes or gene fragments can be used to transform suitable hosts for controlling 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 new classes of pesticidally active proteins and the polynucleotide sequences which encode these proteins. More specifically, in preferred embodiments, pesticidal proteins of approximately 40-50 kDa and of approximately 10-15 kDa are used for controlling corn rootworms. Also described are novel pesticidal isolates of Bacillus thuringiensis.
