North American Mite-A-Thon: May 2nd-17th & August 15th-30th

Mite-A-Thon is a tri-national effort to collect mite infestation data and to visualize Varroa infestations in honey bee colonies across North America within a two week window. All beekeepers can participate, creating a rich distribution of sampling sites in Canada, the United States, and Mexico. Their Varroa monitoring data will be uploaded to www.mitecheck.com.

The parasitic mite, Varroa destructor (Varroa), and the viruses it vectors is a significant driver of this honey bee colony mortality. Yet, indicators suggest that many beekeepers are not monitoring honey bee colony Varroa infestations and therefore not able to connect infestation to colony loss.

OBJECTIVE: 1) To raise awareness about honey bee colony Varroa infestations in North America through effective monitoring methods. 2) Management strategies will be made available for discussion within bee organizations utilizing Mite-A-Thon partner developed information and outreach materials.

DATES:

Spring: May 2nd-17th, 2020

Summer: August 15th-30th, 2020

PARTICIPANTS: All beekeepers in North America are encouraged to participate

COST: There is no cost. You can create your own test materials or kits can be purchased online and at your local bee supply store.

OUTREACH: Promotion of Mite-A-Thon will be through local bee clubs, state beekeeping organizations, and national associations (see partners for examples)

DATA COLLECTION: Participants will monitor the level of mites (number of mites per 100 bees) using a standardized protocol utilizing two common methods of assessment (alcohol wash or powdered sugar roll) and then enter data, including location, total number of hives, number of hives tested, local habitat, and the number of Varroa mites counted from each hive. The published information will not identify individual participants.

Tips: Due to potential shortage of isopropyl alcohol caused by the COVID-19 pandemic, we have heard from some of our experts that winter-grade windshield wiper fluid (methyl hydrate) works as well and may be easier to obtain. Thanks to Meghan Milbrath (Michigan State University), Peter Armitage (Newfoundland and Labrador Beekeeping Association), and Geoff Wilson (Saskatchewan Provincial Apiarist) for the advice.


SPONSORS: Sponsorships are being solicited to underwrite costs and grants, as necessary.
