  • insects require living parts of plants for their reproduction or development. For example, Bark beetle and rape beetle in living parts of plants to lay eggs there. Certain insect species, such as e.g. Plants harmful butterflies, longhorn beetles and European beetles lay their eggs on plant parts and the hatching larvae go into woody, living plant parts for their further development. Other insects eat on leaves, needles but also on bark.
  • cork oaks For cork oaks, the valuable cork should be protected from the ingress of cork oak beetle.
  • Various insects hibernate in the bark of living trees and migrate in spring to feed in the treetops. Even in the root area itself and around plants live active pests (such as citrus longhorn beetle, cockchafer, leaf wasp and weevil), which are to prevent the hatching or excursion as well as bark and trunk feeding.

L'invention a pour autre objet des plantes vivantes dont la surface du tronc, du pseudo-tronc, des branches, des racines avec la motte et/ou de la zone racinaire de la plante est recouverte d'une structure plane qui est imprégnée d'un insecticide. L'invention concerne également une structure plane rectangulaire qui est imprégnée d'un insecticide et comporte un moyen de fixation qui, après recouvrement tubulaire de la surface du tronc, pseudo-tronc ou branche d'une plante, permet un maintien durable sur celle-ci. L'invention concerne également une structure plane, qui est imprégnée d'un insecticide et a la forme d'une plaque perforée qui présente une interruption continue entre le bord extérieur et le bord intérieur. Enfin, elle concerne aussi l'utilisation de la structure plane pour protéger des plantes vivantes d'insectes nuisibles.
