After the withdrawal of Fumagillin, there is no drug which is sufficiently effective against nosema disease. Therefore, intensive research is conducted in order to find new nosemacides. Microsporidia from the genus Nosema are regarded one of the causes of Colony Collapse Disorder (CCD). Hence, any new compound that may be useful in the nosemathosis treatment may be of great importance for veterinary practice. The aim of the study was to assess the effect of a nanosilver-supplemented diet on worker-bee longevity and on the level of worker-bee infection with Nosema spp. in honeybees in cage tests. The diet supplemented with 25 ppm of nanosilver decreased the number of nosema spores. Therefore the compound might be considered as useful in the nosemosis disease therapy. On the other hand, in experiment I, supplementation of the syrup with 25 ppm of nanosilver significantly shortened worker-bees’ lifespan. This, however, was not observed in experiment II. Honeybees fed with syrup supplemented with 25 ppm of nanosilver consumed the greatest amounts of the syrup. Moreover, bees fed with syrup supplemented with 12.5 and 25 ppm of nanosilver exhibited increasing contents of silver in their bodies.

After the withdrawal of fumagillin, there is no effective drug against Nosema disease in the EU. Therefore, intensive research is conducted in order to find new nosemacides. Probiotic microorganisms compete with pathogenic microbes in the gastrointestinal tract. This competition involves adhesion to the intestinal epithelium, which leads to greater availability and utilisation of nutrients. The aim of this study was to determine the effect of a probiotic supplement in the apian diet on the mortality and food ingestion of honeybees, and especially on the course of Nosema spp. infestation. In experiments 1 and 2, the addition of the probiotic caused an increase in the Nosema spp. infection in the summer and winter honeybees. A special probiotic dedicated to the apian diet should be developed.

Porównano wpływ dodatku cukru pudru, syropu cukrowego, preparatu pektynowego i kwasu L-askorbinowego, stosowanych w różnych postaciach i kombinacjach, na jakość mrożonych malin do wykorzystania jako desery. Najwyższą jakość mrożonek po 12 miesiącach przechowywania zapewnił 60 % syrop cukrowy oraz syrop cukrowy z dodatkiem 0,5 % preparatu pektynowego.
