SummaryNosema apis and Nosema ceranae are causative agents of Nosemosis in the honey bee Apis mellifera, although N. may cause a more virulent disease. Selection colonies with high tolerance to could be important for reducing problems caused by this pathogen. The aim present work was evaluate existence different degrees infection test if difference related immune response or vitellogenin expression. Healthy were relocated plantation Eucalyptusgrandisto favour natural ceranae. Fifteen thirty days after relocation, proportion infected bees number spores per field quantified. higher lower levels (HL LL, respectively) selected. Newly emerged from both artificially ceranaeand seven expression genes evaluated real time PCR. No significant differences observed abaecin, hymenoptaecin, defensin, glucose dehydrogenase lysozyme mRNA between HL LL control colonies. Vitellogenin colony than colony, when compared them. This protein possesses pleiotropic effects is central element life-history bees. For that reason, its differential associated resistance
