Abstract: This study was planned to determine the prevalences of the Nosema spp. and the black queen-cell virus (BQCV) among honeybees (Apis mellifera) raised in the province of Van by PCR and to determine the molecular characteristics of the determined isolates. A total of 260 adult worker bees from 26 colonies at 5 apiary locations belonging to the province of Van in April and May 2015 were collected for this reason. Samples were examined microscopically. In the case of positivity, spore identification was done by multiplex PCR. Reverse transcription/PCR analysis (RT/PCR) was carried out for the BQCV analysis. At the end of the microscopic examination, Nosema spp. spores were detected in 8 out of 26 colonies (32.5%). The result of multiplex-PCR revealed Nosema ceranae positivity in all of the samples, but no Nosema apis was determined. As a result of the RT/PCR tests of the samples BQCV was detected in 23 (88.5%) of the total 26 colonies. This study is the first to investigate Nosema spp. and BQCV with the PCR technique in bees raised in the province of Van.
