Abstract
Disclosed are Bacillus thuringiensis strains comprising novel crystal proteins which exhibit insecticidal activity against coleopteran insects including red flour beetle larvae (Tribolium castaneum) and Japanese beetle larvae (Popillia japonica). Also disclosed are novel B. thuringiensis crystal toxin genes, designated cryET33 and cryET34, which encode respectively the coleopteran-toxic proteins, CryET33 (29-kDa) crystal protein, and CryET34 (14-kDa) crystal protein. Also disclosed are methods of making and using transgenic cells comprising the novel nucleic acid sequences of the invention.
