The first detection of Nosema ceranae (Microsporidia) in the small hive beetle, Aethina tumida Murray (Coleoptera: Nitidulidae)

In order to investigate the possible infection of Nosema ceranae in small hive beetle (SHB), Aethina tumida, in 2017, beetle specimens were sampled in Gainesville (Florida). By Real-Time PCR (qPCR), using previously developed primers based on the 16S rRNA gene, N. ceranae was detected in 7 out of 10 SHB specimens, proving that the microsporidia can be transmitted by the alien beetle. This is the first report of N. ceranae infection in A. tumida, although evaluated on a few specimens.
