The present invention belongs to an insecticide compound derived from a strain ofand refers to the field of controlling plant pests, particularly to the control of the boll weevil&#x2014;. More specifically, the object of the invention refers to a new gene for the new delta-endotoxin designated Cry8Ha and to the cloning and expression of the gene that encodes for the protein Cry8Ha in. There is provided the nucleotide sequence and encoding protein of the new delta-endotoxin, recombinant vectors and host cells. There is also provided processes and means for recombinant production and the use of the new delta-endotoxin for application in the control of the boll weevil. Additionally, the invention also provides an optimized synthetic gene for expression in cotton plants. Using the gene described herein, it is possible to transform plants based on techniques known by specialists in the art, for the expression of the endotoxin active against the boll weevil.
