New trends in prevention and negotiation of varroosis

Varroa destructor, in Czech language known as kleštík včelí, is a parasitic mite (of eastern bee and honeybee) which causes the disease called varroasis. Kleštík is like a black passenger on the body of bees and drones, which commonly penetrate foreign hives, and because of that they can be considered the main vector of parasite. In the Czech Republic we fight this parasite using methods every since its discovery in the early 80s of the 20th century. Some methods are defined by the Veterinary Institute in the Czech Republic and the others were disovered by the beekeepers themselves. The main purpose of this thesis was to determine what are current methods to suppress or to completely obliterate the infection caused by Varroa destructor. What methods have proved to be most effective, and what new methods were invented from the time of its discovery. I conducted a field experiment bee hives belonging to beekeeping organizations Trhové Sviny during the 2015 and the 2016. The practical part of my research ( i.e. occurrence and also the review of varroasis disease treatment) had little effect on normal activities of beekeepers. The process of Varroa destructor presence, its treatment and the methods of treatment researched. Based on the collected samples sent to Veterinary Administration for testing to find out whether are the Varroa counter measures effective or not. The conclusion of my reasearch ist he unificated treatment and detection of Varroa are of the main importance. That goes not only for the beekeeping associations but also by unregistered beekeepers. Because the amount of bee colonies here in the Czech Republic is huge, the use of alternative treatment and suppresing procedures as well as the intentional breeding for resistance against Varroa are rather unrealistic, the only viable option fort he moment , is to follow Veterinary Services guidelines
