摘要:
Novel Bacillus thuringiensis isolates with hymenopteran activity are described. Also described are toxins having the advantageous hymenopteran activity.This invention further concerns genes or gene fragments which have been cloned from the novel Bacillus thuringiensis isolates which have formicidal activity. These genes or gene fragments can be used to transform suitable hosts for controlling ants.
摘要:
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.
摘要:
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.
摘要:
The subject disclosure concerns Bacillus thuringiensis strains which can be used to control lepidopteran pests. The strains were previously known to control coleopteran pests. The discovery of lepidopteran activity was totally unexpected.These B.t. strains can be formulated using standard lepidopteran formulation procedures. Means of administration are also standard.The genes encoding lepidopteran-active toxins can be isolated from the B.t. isolates and used to transform other microbes for use to control lepidopteran pests.
摘要:
This invention concerns nematicidal proteins obtainable from Bacillus thuringiensis isolates. The subject invention also provides various methods of using these proteins for controlling nematodes.

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.
摘要:
This invention concerns novel gene probes which can be used to identify DNA from Bacillus thuringiensis microbes which encode protein endotoxins. The invention probes greatly facilitate the search for useful microbes hosting genes which encode toxins.
