Varroa curent has not been found in Victoria, Australia but is present in NSW. At some point it will be in Victoria. It is vial that beekeepers across Australia learm about Varroa and their management options.
Having a good understanding of tested and approved intergrated pest management strategies avaliable and how and when to apply them will be critical for beekeepers.
Currently the best Australian information sources on Varroa is from the NSW Department of Primary Industry
I encourage all to regualarly go to the site for updates on Varroa spread and management options.
