Anti-pest device for fruit trees and the like

A device against pests in fruit trees with a trunk with bark, wherein the device comprises:

• an elongated rectangular sheet of electrical insulating material, defined by a length and comprising a distal end and a proximal end and an internal face and an external face,
• a band of low-density foam, defined by a length, attached to the internal face of the elongated rectangular sheet, wherein the band of low-density foam is any foam adaptable to the bark of a tree and capable of being inserted and faithfully adapted to the reliefs of the bark,
• wherein the elongated rectangular sheet has a greater length than the band of low-density foam in such a way that when the band of low-density foam surrounds the bark of the tree trunk, the distal end of the elongated rectangular sheet is superimposed on the proximal end of the elongated rectangular sheet, and wherein the device additionally comprises:
• elastically deformable elements, that link the distal end of the elongated rectangular sheet to the proximal end that enables said free distal end to slide on the main body of the sheet, thus adapting to the progressive growth of the tree trunk,
• a pair of parallel conducting wires arranged in an open circuit and placed on the external face of the elongated rectangular sheet, separated from each other a distance according to the size of a pest to be exterminated, and
• a power supply circuit, connected to the pair of parallel conducting wires, for subjecting them to a high difference in electrical potential.
