Abstract
A Bacillus thuringiensis strain isolate, designated EG5092, exhibits insecticidal activity against lepidopteran insects. A purified and isolated novel cryET1 toxin gene product from B.t. strain EG5092 exhibits specific insecticidal activity against Plutella xylostella (Diamondback moth). The cryET1 gene (SEQ ID NO:1) has a nucleotide base sequence illustrated in FIG. 1 and produces a CryET1 gene product (SEQ ID NO:2) having a deduced amino acid sequence illustrated in FIG. 1.
