Technické a alternativní metody k šetrnému tlumení varoózy

Varroosis is a disease afflicting beehive on every continent except for Australia. Since 2000 the disease is known to be caused by the Varroa destructor mite. This thesis' first goal was to summarize information about this parasite and the methods limiting its impact. The second goal was to prepare and conduct a test verifying the effectiveness of the ultrasound method, which was carried out with the Varroa-Killer-Sound device. In order to enable the analysis, bee samples from two hives were chosen and those were then tested for the quantity of Varroa destructor females using the sugar shake method. The first sample group consisted of bees treated with the ultrasound method, the latter were control beehives, which were not experimentally treated. Furthermore, other factors were continually measured: temperature, relative humidity, and dew point of the external environment. The results of the research were analyzed by the STATISTICA 12 program
