Definitions

  • the invention relates to a method o f controlling noxious insects which lay their eggs on standing crops.
  • the insects are controlled without being catched or killed by the cyclically repeated light variations affecting the insects in the same manner as the moonlight: the females will be less inclined to lay their eggs on the crops located in the varying light flow and thus these crops will not in a greater or less degree be eaten by the insect larvae.
  • the light intensity varies slowly from a minimum, preferably zero, to a maximum, and it is important as well that the light momentarily returns from the maximum to the minimum, because the insects adapt themselves to a constant light or a uniform, e.g. sinusoidal, light variation.
  • the period between the minimum and the maximum may be e.g. 20 sec. It is not necessary, however, that the light flow as a whole is cyclically varied; only a component of the light flow may be cyclically varied.
  • the slowly varying light flow can be provided by means of an artificial light source which is controlled or supplied by a solid state sweep circuit which can be of an embodiment known in the field of electronics.
  • OMPI thereof is that the number of these insects decreases.
  • the two control measures mentioned above can be combined with each other in an advantageous manner in such a way that before midnight when the major number of eggs are laid, there is provided a light flow in the area wherein the control of insects shall take place, the light intensity of said light flow being varied cyclically from a minimum to a maximum, while the light intensity after midnight when mating takes place, is varied cyclically from a maximum to a minimum.
  • This is illustrated in the accompanying drawing which shows the light intensity (the vertical axis) over the time (the horizontal axis). To the left of the vertical dot and dash line indicating midnight, i.e.
  • the light pulses increase slowly from minimum to maximum in order then to return abruptly to minimum according to a saw-tooth characteristic, and under the influence of this light variation the inclination to oviposition of the insects will be affected.
  • the light variation follows a reversed saw-tooth characteristic and then the mating inclination will be affected.
