Trap for larvae of pine processionary (Thaumetopoea pityocampa)
The necklace has a purely mechanical action and does not contain attractants or phytosanitary products. Acts at a precise and dangerous moment of the processionary. Thanks to the action of the collar the colonies can not finish their development and they will not invade their conifers again.
