The Meliponini is a eusocial group of bees tropically distributed. In Argentina, 37 species have been recorded, mostly in Misiones province. They use a great variety of sites to build their nests including tree hollows, cavities formed in rocks, human constructions or underground spaces. Numerous natural enemies are associated with stingless bees, including viruses. Until now, some viruses present in honey bees and related to the colony collapse disorder (CCD), have been found in several wild bees around the world. Here, we have studied the presence of honey bee viruses in stingless bees from different locations of Misiones province, Argentina. On this research, 73 samples of ten workers belonging to 12 species of stingless bees and feral honey bees, have been analyzed. Our results confirm the presence of three viruses: ABPV, IAPV and DWV Type A in four species of stingless bees and feral honey bees. More studies are required to establish if ABPV, IAPV and DWV are natural pathogens of stingless bees that have been spilled over to honey bees, or were transmitted by Apis mellifera to stingless bees.Facultad de Ciencias Naturales y MuseoFacultad de Ciencias Veterinarias
