1. Introduction

Most honey bee researchers consider the ectoparasitic mite Varroa destructor to be the most damaging enemy of the honey bee. It has been recently identified as one of the major factor responsible for colony losses worldwide (e.g. Brodschneider et al., 2010; Chauzat et al., 2010; Dahle, 2010; Genersch et al., 2010; Guzman-Novoa et al., 2010; Schäfer et al., 2010; Topolska et al., 2010; vanEngelsdorp et al., 2010; Martin et al., 2012; Nazzi et al., 2012). Both the development of new and innovative control methods against the mite and further studies on the complex interaction with the honey bee should be a priority in bee health research (Dietemann et al., 2012). The use of standardised methods by those studying the mite will greatly increase the impact of such work. When reviewing the literature, researchers should take note that publications prior to 2000 mention V. jacobsoni instead of V. destructor. The species name was changed after Anderson and Trueman (2000) demonstrated with molecular tools that the invasive population was not the species from Indonesia described by Oudemans in 1904.
