Honey bee, Apis mellifera L., have been widely used as a model organism for biological science because of its highly developed sociality, specialized labor division and passive population management. In order to examine the expression patterns of genes putatively involved in social development in honey bee, quantitative real-time PCR (qRT-PCR) that has been widely used to investigate the expression level of target gene can be used in honey bee study. However, the selection and validation of optimal reference genes is a crucial step prior to running qRT-PCR. In the present study, therefore, the seasonal expression stability of five candidate reference genes in the abdomen of forager and nurse was investigated using three programs (geNorm, NormFinder and BestKeeper), and selected reference genes were validated by the normalization of expression level of vg encoding vitellogenin. Although three programs revealed slightly different gene stability values, overall the combination of two genes (rpS18 and gapdh encoding ribosomal protein S18 and glyceraldehyde-3-phosphate dehydrogenase, respectively) was resulted in the most suitable use for normalization of the target gene in forager. However, a single gene, either rpL32 or rpS18 in the nurse or either rpL32, rpS18, or gapdh in the comparison between foragers and nurses, were suggested to be applied for normalization of seasonal and labor-specific gene expression by qRT-PCR.
