Study of fluvalinate residues in honey and wax after treatment of bee colonies in varroatosis


T.F. Domatskaya, A.N. Domatsky

In three experiments on 18 bee colonies of the apiaries of Tyumen Region, the fluvalinate level in honey and wax after treatment of bee colonies with the following veterinary preparations has been studied: Tanis, Acaricidal bath, Varroplast M. Bee colonies were treated with drugs according to the application instructions. 7 days after treatment, wax and honey samples were taken from each colony and studied for active substance using gas-liquid chromatography. 36 wax samples and 18 honey samples were studied in total.A study does not reveal any fluvalinate residues in samples of honey and wax after treatment of bee colonies with Tanis. In bee colonies treated with Acaricidal bath, the fluvalinate level in wax selected from the brood frames averaged 0.97 ± 0.12 mg/kg, from honey frames - 0.12 ± 0.01 mg/kg in honey - 0.0026 ± 0.0002 mg/kg. A significant number of fluvalinate was found in bee colonies treated with Varroplast M. The fluvalinate level in wax samples from brood frames was 1.4 ± 0.09 mg/kg. Studies of wax taken from the honey frames indicated that there were fluvalinate residues of average 0.28 ± 0.08 mg/kg, the amount of drug in honey was 0.005 ± 0.001 mg/kg. It was found that the greatest number of fluvalinate residues is present in wax samples obtained from the brood frames. In the experiment with Acaricidal bath, the active substance level in wax from the brood combs significantly exceeded similar indicators of wax taken from honey frames (td=7.08). In the experiment with Varroplast M, the number of fluvalinate in wax samples taken from the brood frames is significantly higher than the data on wax from honey frames (td=9.3). Analysis of the results of own studies and literature data shows that the honey products should be monitored for acaricides residues, used to treat bee colonies in varroatosis in the apiaries of the Russian Federation.
