Abstract(s)
Portuguese beekeepers depending on blind and repeated use of amitraz in
fighting Varroa have meant a selection pressure towards amitraz-tolerant Varroa
populations. Some of these Varroa populations were recently pin pointed during
a nationwide monitoring effort (by field and laboratory testing), allowing for
investigating the practical meaning such increased levels of tolerance have to
properly applied Apivar field treatments and how quickly those populations
regress to normal levels of susceptibility to amitraz.
