Monitoring Varroa jacobsoni resistance to pyrethroids in western Europe

Abstract - Since 1991, Varroa jacobsoni resistance to pyrethroids has been reported to occur in several European countries. Monitoring surveys were performed in 1995, 1996 and 1997 in Europe using a laboratory assay to localise possible foci of resistance. A resistant strain seems to have originated in Italy, and spread to Slovenia, Switzerland, France, Belgium and Austria. The areas where Varroa jacobsoni resistance to pyrethroids have been detected are indicated in this paper. © Inra/DIB/AGIB/Elsevier, Paris
