Nosema apis is a serious parasite of adult honey bees. It has been reported to cause significant production losses as a result of a range of effects on adult bee longevity, queen bees, brood rearing, bee biochemistry, pollen collection and other bee behaviour. Despite these effects there are no classic signs of infection and hence most infections are unrecognised. There is no comprehensive current data on the prevalence of nosema disease in bees in Australia and no work which links nosema disease with beekeeper management practices.
The literature review is provided in the first section of the report. It provides details on the cause, occurrence, multiplication and spread, and effects on adult bees and honey bee colonies. Information is also provided on the diagnosis, factors affecting nosema spore counts and control methods
