The present invention provides a method for the preventiontreatment of bark beetle andor wood borer infestation of trees comprising treatment of the tree with a composition comprising a macroyclic lactone. The speed sensor and the electronic control unit are interconnected by at least one line. The deteriorated state of the hydrocarbon adsorbent is evaluated based on the deterioration evaluating parameter. The assembly surface of the carrier substrate is placed on a contact surface of the main board, and a filling material is provided between the contract surface of the main board and the assembly surface of the carrier substrate.
