Abstract
Novel insecticidal toxins isolated from Bacillus thuringiensis that are active against lepidopteran insect pests are disclosed. The DNA encoding the insecticidal toxins can be used to transform various prokaryotic and eukaryotic organisms to express the insecticidal toxins. These recombinant organisms can be used to control lepidopteran insects in various environments.

A Cry1I toxin comprising 719 amino acids and having at least 99% identity with SEQ ID NO:
- 1, wherein the amino acid corresponding to position 140 is glutamic acid (E), the amino acid corresponding to position 184 is threonine (T), the amino acid corresponding to position 233 is aspartic acid (D), the amino acid corresponding to position 329 is isoleucine (I), the amino acid corresponding to position 377 is threonine (T), the amino acid corresponding to position 393 is phenylalanine (F) or leucine (L), the amino acid corresponding to position 549 is leucine (L), and the amino acid corresponding to position 712 is leucine (L) or glutamine (Q).
A method of reducing pest damage in a transgenic plant caused by Lepidopteran insects and Coleopteran insects, the method comprising planting a transgenic plant seed comprising a first transgene and a second transgene, wherein the first transgene causes expression of a Cry1I toxin and wherein the second transgene causes expression of a Cry3 toxin;
- thereby reducing damage caused by Lepidopteran insects and Coleopteran insects to a transgenic plant grown from the transgenic plant seed.
