Gilliam (1997), reported that yeasts and molds are found naturally in the honey of honeybee. It is believed that microorganisms associated with bees are non-pathogenic. However, not all bees contain molds and the presence of molds are varied from colony to colony. Molds could contribute to the antimicrobial compound secretion to prevent stored food spoilage. They are also contributing to organic acids and other metabolites production (Gilliam et al., 1989; Gilliam, 1997).
A terrific relationship between stingless bees and a fungus recently has been described by Menezes et al. (2015). A social bee from Brazil (Scaptotrigona depilis) must eat a fungus of the genus Monascus (Ascomycotina) to survive. This fungus is transmitted to other bee generations
