    Abstract

    The impact of varroa and pollen flow on hemolymph vitellogenin was studied on colony level. It was demonstrated that the number of mites in the August-September period, negatively impacts the fraction hemolymph vitellogenin. Colonies which had an impeded pollen flow from June till August also had a significantly reduced fraction hemolymph vitellogenin. The fraction vitellogenin of the total hemolymph protein appeared to be a more robust fitness parameter than hemolymph vitellogenin titers expressed as µg vitellogenin per µl hemolymph. In colonies which had, due to impeded or non impeded pollen flow, significant different fraction hemolymph vitellogenin in September, no quantitative differences expressed as number of bees and sealed brood cells, were recorded. It is conceivable that colonies that have a mean relatively low fraction hemolymph vitellogenin, have less chance to overwinter, particularly if poor pollen flow and inadequate varroa control are coupled
