Abstract

Nosema is a genus of 81 microsporidian parasites, two of which affect honey bees. The advent of molecular methods has facilitated the differentiation between Nosema apis and Nosema ceranae. N. ceranae infection was detected by polymerase chain reaction (PCR) in an apiary on the Coromandel Peninsula of New Zealand during investigation into unusual colony losses in early spring 2010, and was subsequently found in other areas of the country. While no association could be confirmed between apiary health status and presence of N. ceranae, a significantly higher proportion of positive apiaries were detected in spring compared with autumn. PCR for N. ceranae conducted in three different laboratories showed fair agreement. Minor assay differences and sample level variation in Nosema are the most likely explanation for differences in results.
