- Abstract
The aim of the work was a determination if water nanosilver solution may be applied in a prevention of chalkbrood of honey bee colonies. The study was conducted on bee colonies where clinical symptoms of chalkbrood were stated. In 5 bee colonies the solution of nanosilver in a spray form of a concentration of 30 ppm in 5 colonies - 50 ppm was used, and 3 colonies were control ones, without a treatment. Nanosilver solution was applied in a form of spray on honeycombs with bees and a brood and on internal walls of hives. The treatment was conducted 5 times, in 5-days intervals. One day after spraying and on a day of the subsequent spraying (before the treatment) the inspection was done, and mummies of petrified larvae present in honeycombs were counted. After nanosilver solution application of a concentration of 30 ppm, any distinct differences in a number of bee larvae mummies found in honeycombs were observed. More differentiated results were obtained in groups where a solution of a concentration of 50 ppm was used. After five days from the last spraying with nanosilver no even one mummy was found in a one bee colony, and in two others 3-5 mummies on one side of a honeycomb were noted. In turn, in the two remaining colonies the negligible changes in a number of petrified larvae were demonstrated - 7-9 petrified larvae. The result of nanosilver solution application was a distinct increase in Ag concentration in organisms of worker bees and in honey - in bees from a concentration of <0.07 μg.g-1 d.m. to 4.28-5.62 μg.g-1 d.m., and in honey from <0.03 μg.g-1 d.m. to 0.38-1.57 μg.g-1 d.m. Any negative influence of a high level of silver on an organism of a bee was observed.
