Effectiveness of Apiwarol applied by electric smoker for control of Varroa destructor in honey bee colonies
The use of electric smoker for the application of Apiwarol is a practical method for Varroa destructor control in honey bee colonies. However, according to some reports this method may decrease the efficacy of the drug. The aim of this study was to compare Varroa control in colonies treated by the electric smoker Wakont and in the traditional method. Twenty colonies were investigated. They were fumigated four times every four days. The electric smoker was used in ten colonies and in another ten colonies the tablets were smoked inside the beehives on the bottom board. Bottom traps were inserted in hives to collect and count dead Varroa. A day after the last fumigation treatment, a sugar roll test was applied to assess the number of mites left on bees. There were no statistically significant differences in the Varroa fall during the treatments and in the number of mites left on bees after the treatments between these two groups. We did not ascertain a decreasing of the effectiveness of Apiwarol after application by using the electric smoker.
