Definitions

• the present invention relates to a method and a device for controlling mites.
• it relates to the use of sound waves in a certain frequency range to combat mites.
• Mites (order Aca ⁇ ) belong to the arachnids (Arachnida) from the arthropod trunk (Arthropoda). The order is divided into approximately 200 families with a total of approximately 40,000 species. The mites include numerous species that are also of economic importance as pests. Previous control methods have mainly used chemical agents that can lead to undesirable residues, especially in the food sector.
• the object of the present invention is therefore to provide a method and a device for controlling mites by means of which the use of any means which are questionable from an environmental and health point of view can be avoided and which does not lead to any residues.
• a device suitable for controlling these pests comprises, for example, a tone generator which has frequencies in the range from 12000 to 17000 hertz with constant or variable pitch and / or constant or variable sound power generated, and a sound radiation device, such as a piezoelectric speaker.
• This device is provided either in or in the immediate vicinity of a beehive.
• the sound power at the place of action should preferably be in the range of 10 ⁇ 7 and 10 -4 W / m 2 .
• the Varroa mites react to sound waves of the aforementioned intensity in the (broader) range between 7000 and 17000 Hertz, but bees can also perceive sound waves in the range below 12000 Hertz and react to them with increased restlessness. In the range between 12000 and 15000 hertz, however, no harmful effects on the bees could be found even with sonication over two months. At the beginning of the sound system, Varroa mites stop their normal movements and start to tremble uncontrollably.
• Young mites such as those found on bee larvae die almost completely within one hour at a sound power of more than 10 ⁇ 6 W / m 2 . Older mites, such as those found on adult bees, are more resistant and only die after sonication lasting from several hours to several days.
