Method and device for the automated registering of insects (12) present on a catch plate (5). The catch plate is introduced into a device (1) and scanning of the catch plate is carried out with the aid of a camera (8) and light (10). The presence of insects, like the number of insects, is determined based on vision technologies. Optionally with the intervention of a remotely positioned central processing unit (16), a signal is issued, based thereon, if a threshold value is exceeded. Based thereon, it is possible to take measures, in for example a growing space where the catch plates are positioned, in order to counteract undesirable phenomena.
