Some of the More Important Factors Governing the Flight of European Corn Borer Moths to Electric Traps1

Previous investigations of the use of electric traps as a possible method of controlling the European corn borer have given promising results, and the problem of putting this method of control on a more practical basis has been the subject of further investigation. The main factors affecting the flight of the moths to the traps as a means of further increasing the number captured and the percentage of control in the trapped areas have been given primary consideration. These factors include studies on the placement of traps with regard to field contour, the height of trap operation, the trap type and the most effective type of lamp to use as a lure. Such factors bear a close relationship to the cost of installation and operation of any plan for controlling the corn borer by means of electric traps and the practical application of radiant energy.
