Abstract The present studies are the second part of research project dedicated to finding causes for increased winter mortality honey bee colonies. aim this task was investigate incidents overwintered colonies′ death with regard potential interrelation exposure pesticides. samples stores bread and sugar food (honey or syrup processed by bees), beeswax bees collected from apiaries low high rates colony were searched acaricides used control V. destructor plant protection presence in apiculture has been detected 51% samples. most abundant acaricide tau-fluvalinate. had a similar frequency pesticide occurrence, ranging between 50-60%, but number active substances their concentrations substantially lower prevalent pesticides pollen fungicides (carbendazim boscalid) insecticides (acetamiprid thiacloprid). Only few found several dead bees. level contamination (frequency, concentration, toxicity) hive products originating both survival rates, similar, which created extent risk. Although multiple varroacides environment we not unequivocal links residues mortality.
