MartaĪbstract Over the past decade in North America and Europe, winter losses of honey bee (Hymenoptera: Apidae) colonies have increased dramatically.
Beside their pathological effect on honey bees, classification and taxonomy of these protozoan parasites should also be clarified.Ī Bio-Economic Case Study of Canadian Honey Bee (Hymenoptera: Apidae) Colonies: Marker-Assisted Selection (MAS) in Queen Breeding Affects Beekeeper Profitsīaylis, Kathy Hoover, Shelley E. The role of other pathogens in colony collapse has to bee studied in future, especially trypanosomatids and neogregarines.

The results of this study demonstrate that the drivers of colony collapse may differ between geographic regions with different environmental conditions, or with different beekeeping and agricultural practices. This means that the latter group corresponds to a highly differentiated taxon that should be renamed accordingly. mellificae sequences obtained in our study or published. The genetic analysis of trypanosomatids GAPDH gene, showed that there is a large genetic distance between Crithidia mellificae ATCC30254, an authenticated cell strain since 1974, and the rest of the presumed C. Consequently, the pesticide residue analysis was negative for neonicotinoids. Palinologic study of pollen demonstrated that all colonies were foraging on wild vegetation. Other viruses, Nosema apis, Acarapis woodi and Varroa destructor were not detected. Moderate prevalences were found for Black Queen Cell Virus and trypanosomatids, whereas Deformed Wing Virus, Aphid Lethal Paralysis Virus strain Brookings and neogregarines were rarely detected. Omnipresent were Nosema ceranae and Lake Sinai Virus. Colonies with typical honey bee depopulation symptoms were selected for multiple possible factors to reveal the causes of collapse.
