Improvement of the toxicities of The Cry Proteins of Bacillus thuringinesis Caderina Fragments for Beetles and insects

摘要

A fragment of Caderina Worm Maize Roots of Western Power cry3 toxicity to the larvae of Species Naturally susceptible. Also, a fragment of a Beetle Caderina enhances the toxicity of cry3aa and cry3bb for coleopteors larvae, especially those of the family of the Chrysomelidae.Claim 1: a polypeptide which encodes a Protein of Bacillus thuringiensis Cry, includes a segment where the polypeptide that binds to the Protein Cry where this segment comprises at least 85% Sequence identity with a binding domain Protein Cry of CAD Erina coleopteran Insect midgut of an.Claim 2: a method for the inhibition of a Beetle, wherein Said method comprises providing to said coleopteran Cry Protein from Bacillus thuringiensis for ingestion, together with a polypeptide that includes a segment that binds to the Protein Cry,This segment comprises at least 85% Sequence identity with a binding domain Protein cry a Caderina a coleopteran Insect midgut and where this Beetle is not a Worm of the Roots.
