Sažetak
Because of the possibility of resistance to multiple administrated synthetic acaricides and very variable effectiveness of used treatments, there is a current need for utilization new treatment methods with natural phytopharmaceutical preparations and/or food additives. Also, the effects of residues and their by-products in honey and wax present environmental concerns and are another reason for reducing the use of conventional chemical mite- and parasite-control methods in beekeeping. The aim of this study was to examine the effectiveness of triple application BeeVital Hive Clean preparation in removing varroa mites from honey bee colonies during the active beekeeping season. This is a natural preparation containing oxalic and citric acids, extracts of propolis and different essential oil recipes. It represents an eco-friendly preparation in the form of food additive for honey bees. The number of mites was recorded on three occasions in the pre-treatment period, and then recorded regularly once a day for 24 days after treatments began. The treatments were performed three times with six days apart using the “drench method” according the manufacturer’s instructions. The control group of honeybee colonies was treated with sugar powder. Mite mortality after BeeVital Hive Clean application in the period from 16th of July to 7th of August, was higher (P <0.05) compared to natural mite mortality in the pre-treatment period. Also, the total number of fallen mites during the experiment was significantly (P >0.05) different between the treated and control groups. After the second treatment we determinated 41.72%, and after third treatment 31.30% more fallen mites in comparison with first one. After last treatment there was 75% more of fallen mites in comparison with treatment before that. All treatments together achieved 91.6% efficiency of varroa mite control. Further experiments should be conducted in order to establish how to increase the efficacy of mite control in highly infested colonies during the period of brood rearing under continental climatic conditions.
