New Bacillus thuringiensis Cry protein with insecticidal activity to combat a hemíptero.

摘要

The invention relates to a novel gene encoding a Cry (or delta-endotoxin) protein, to the actual protein encoded by said gene, to the systems for the expression of same (vectors and host cells), and to the use of said gene and/or said protein for controlling hemipteran pests, preferably the green aphid, Myzus persicae, both by using a composition containing the novel protein and/or a system for the expression thereof, and by using transgenic plants wherein the gene is expressed. Said transgenic plants and compositions are especially interesting as the novel Cry protein has an especially good insecticide capacity against Myzus persicae compared to other known Cry proteins which exhibited a smaller insecticide capacity against aphids and none were known to be active against Myzus persicae.
