Research into Nosema in honeybees is progressing but not enough is known about it to provide standard treatment recommendations.  In addition, known strategies may vary between N. ceranae and N. apis which we are unable to differentiate with light microscopy.  The following are resources to help you decide which management and treatment strategies are right for you.

Diagnosis results are reported as 'number of spores per bee'; it's understood that most northern colonies can tolerate up to 1 million spores per bee, though beekeepers should be aware and employ additional management strategies to control infection level.  Diagnosis of your bees will provide you information on the level of Nosema infection your colony may have.  Results will be reported in the following categories:

High = Greater than 5 million spores per bee

Medium = 2.1 million - 5 million

Low = 100,000 - 2 million

Detectable limit = 100,000
