Abstract - A new infectious disease of Apis mellifera, Bombus hortorum and B terrestris is reported to be caused by a parasitic protozoan belonging to the order Neogregarinida. The disease can be diagnosed based on the presence of characteristic navicular spores measuring 11.4-14.4 x 3.6-5.4 μm. Infection level in host populations was low but since this parasite was found in host insects in Finland and Italy, it evidently has a wide distribution in Europe.
Key words: Apis / Bombus / neogregarine / protozoan / parasite
