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:
Novel B.t. genes encoding toxins active against lepidopteran insects have been cloned from a novel lepidopteran-active B. thuringiensis microbe. The DNA encoding the B.t. toxin can be used to transform various hosts to express the B.t. toxin.

摘要:
Disclosed and claimed are toxins produced by novel Bacillus thuringiensis isolates designated B.t. PS92J, B.t. PS196S1, B.t. PS201L1, and B.t. PS201T6, which have dipteran and/or corn rootworm activity. Thus, the isolates, or mutants thereof, can be used to control such pests. Further, claimed are novel genes encoding these .delta.-endotoxins, which can be expressed in other hosts. 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 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.
