Abstract

In a method and device for influencing insects by means of electromagnetic radiation, a transmitter generates a time-based progression of an antenna feed with pulses, which is emitted via an antenna as electromagnetic radiation having corresponding pulses. The antenna feed comprises bursts, or packets or salvoes, of pulses, wherein the time interval between directly successive pulses of a burst is in the range from 5 με to 9 με and the time expansion of the burst is at least 0.1 ms. Because of the intensity gradients that arise in a radial direction around an antenna, a movement leading towards the antenna is, for insects, directly associated with an increase in perception intensity and a movement leading away is associated with a decrease. The insects perceive the gradient and tend to move such that the irritating perception decreases for them.

Claims

1. A method for influencing insects by means of electromagnetic radiation, in which method a time-based course of an antenna supply with pulses is generated by a transmitter and is radiated via an antenna as electromagnetic radiation with corresponding pulses, wherein the antenna supply comprises bursts, or packets or salvoes, of pulses, wherein the time interval between directly successive pulses of a burst is in the range from 5 μ

s to 9 μ

s and the time extension of the bursts is at least 0.1 ms.

2. The method according to claim 1, wherein the time extension of the bursts is at least 1 ms, and preferably lies in the range from 1 to 4 ms, in particular 2 ms.

3. The method according to claim 1, wherein the time extension of the burst is at least 3 ms.

4. The method according to claims 1, wherein the time intervals between bursts following one another at short intervals are at least 50 ms and preferably lie in the range from 70 ms to 100 ms.

5. The method according to claim 1, wherein the number of bursts following one another at short intervals is at least three, but preferably in the range of three to ten, in particular four.

6. The method according to claim 1, wherein the time interval between successive series of bursts following one another at short intervals is at least 1 s, but preferably in the range from 1 s to 3 s, in particular 2 s.

7. The method according to claim 1, wherein all pulses of a burst, preferably also all pulses of a series of bursts following one another at short intervals, are formed of the same positive or negative type and preferably a predetermined proportion of the pulses of a burst reaches a predetermined pulse height.

8. The method according to claim 1, wherein the transmitter generates a modulated signal, preferably by means of amplitude modulation, using a carrier frequency in the range from 10 MHz to 24 GHz, preferably from 300 to 450 MHz, in particular from 433 MHz.

13. The device according to claim 7, wherein the transmitter makes the antenna supply producible in such a way that the number of bursts following one another at short intervals is at least three, but preferably in the range from three to ten, in particular four.

14. The device according to claim 7, wherein the transmitter makes it possible to generate the antenna supply in such a way that the time interval between successive series of bursts following one another at short intervals is at least 1 s, but preferably lies in the range from 1 s to 3 s, in particular at 2 s.
