Most of the phenomena described in that Wikipedia list are just manifestations of quantum fields. The descriptions in terms of virtual particles are sometimes convenient, but they are only ever heuristics, not descriptions of what is really going on. See Neumaier's article that I referenced, or the related articles that he links in his first paragraph. He explains the real physics behind many of these phenomena.
