Field Day: Varroa-Tolerant Bee Breeding Program, Sept. 22, 3–5 p.m., Free

img_20180813_111002765The Low Technology Institute is running a breeding program to establish varroa-tolerant colonies in a semi-isolated area. The essence of the process is to split hives aggressively to have as many reasonably strong colonies as possible going into winter and then heavily splitting those that survive. Without treatment, colonies with poor tolerance will succumb to mite infestation, while those with some defense mechanism (genetic, behavioral, or both) will survive and be split to make the new population. Over years, this can create a varroa-tolerant colony, as shown in European trials.


This field day will consist of a presentation of the project with time for discussion afterwards. We can visit a few of the colonies around the village. Light refreshments will be served. A recording of the presentation will be available online afterwards.

  1. This is a great class you’re offering. It would be fantastic if you filmed it and posted it on your website to get the message out to beekeepers everywhere.
