A rotary insect trap is provided comprising a receptacle having an opening which is closed by an elongated rotor having a number of wings. Some of the wings are always in contact with the opening boundaries closing the interior of the trap receptacle against the surrounding. The rotor wings extend substantially across the whole length of the rotor and are shaped or made with a plurality of slots being in parallel with one another and extending rectangularly onto the rotor axis so that they separate gill-shaped radial portions of the wings from one another. A comb-shaped member comprising a plurality of teeth, pins or gills is arranged in the opening so that the teeth or the like engage each individual slot in the rotor for cleaning the surfaces of the wings when the rotor is rotated. The rotor can comprise a plurality of radial gills mounted spacingly onto a rotor shaft or can be moulded as an integral piece. |
