Honey Bee Parasites
If, as seems to be the case, the virus complex is associated with Varroa mites, then controlling the mites is important in controlling or at least combating the viruses. Because many of these infected colonies seem to collapse or the bees seem to "disappear" in early fall, it is necessary to control the mites well before this time. Currently, Apistan is the only legal material registered for the control of Varroa mites in the United States. If used according to label directions, Apistan is effective in controlling Varroa mites.
