The rapid spread of V. destructor across Oahu and the Big Island, along with the high mite infestation levels observed (Villalobos, 2010), have precipitated major changes in the viral landscape of honeybee colonies in Hawaii (Martin et al., in preparation). The large parasitic pressure of the mite and the now widespread distribution of Varroa transmitted bee viruses, such as the Deformed Wing Virus, threaten the sustainability of the Hawaiian beekeeping industry and have created an urgent need to examine which mite control options are most suitable for local conditions. In this document, we have gathered information on Varroa treatments, the pros and cons for each method, particularly with respect to chemical residue, and the suitability for use in tropical climates. In addition, we have undertaken an online beekeeper survey to assess the impact of V. destructor and document beekeepers' management and treatment strategies. The results of this survey constitute a benchmark reference for Hawaii and will contribute to a better understanding of the practices and needs of the local beekeeping community.
