> Nowadays there is no doubt that the impact of various syndromes implying bee viruses is a global threat for apiculture. Can we expect that naturally or artificially selected honey bee lines could alleviate this impact? Are the developments of new treatments against virus infections really promising? And can we still prevent undiscovered viruses (or other agents that favor their active multiplication) from disseminating worldwide? Answering these questions is forecasting the future of virus infection in the honey bee.

> Until now, the spontaneous or artificial selection of honey bee lines more tolerant to V. destructor infestation have produced poorly productive colonies. However, no simple and economically acceptable treatment against virus infections are in view for replacing the heavy and not always efficient acaricide treatments which have already selected resistances in the target species.

> The dramatic increase in emerging virus diseases in the honey bee may still be worsened by the continuing development of international exchanges and the potential dissemination of still undiscovered viruses or other agents that may favor their active multiplication.
