I am posting this on behalf of Medhat and his associates. Great work, team!
Currently, populations of Varroa mites globally have developed resistance to pyrethroid and organophosphate miticides. More recently, resistance has been emerging to the only remaining viable synthetic miticide, Apivar. Since Apivar registration in 2008 in Canada, I have recognized the need for active ingredients (AIs) with different modes of action to support developing alternative miticides to control varroa and keeping healthy bees.
I am so proud of the research that was done by the Alberta Agriculture Bee Team, led by Rassol Bahreini and I has been published in Nature Scientific ReportsToday. This research report is now available for you to access by using the following link:

Over all 16 active ingredients and 9 of their formulated products belong to 12 different families screened under lab conditions against varroa mites and bee safety. So far 5 products showed significant toxicity to varroa mites, but two out of them were safer to bees at tested concentrations. These active ingredients are recommended for further testing at the colony level and can be developed to become potential varroacides for use by beekeepers.
I am very proud of this study, and all the hard work and contributions of all team members. This is a good day to lead the way for having new alternative miticides in our toolbox for varroa control. We thank our funding agents Alberta Crop Industry Development Fund (ACIDF), Alberta Beekeepers Commission, Growing Forward2 (a federal- provincial, territorial initiative) and Canadian Bee Research Fund (CBRF) and Government of Alberta for their support.
