  • Bacillus thuringiensis isolates active against lepidopteran pests, and genes encoding novel lepidopteran-active toxins
    Patent number: 5407825
    Abstract: Novel Bacillus thuringiensis genes encoding toxins which are active against lepidopteran insects have been cloned from novel lepidopteran-active B. thuringiensis microbes. The DNA encoding the B. thuringiensis toxins can be used to transform various prokaryotic and eukaryotic microbes to express the B. thuringiensis toxins. These recombinant microbes can be used to control lepidopteran insects in various environments.
