Testing for Hygienic Behavior

Last Thursday we started with our first two days of breeder sampling at Pendell-Apiaries in Stonyford, CA. Breeder sampling includes colony assessments, hygienic, Varroa, Nosema, and virus testing. Katie did a tremendous job in the field explaining and guiding the team through the tasks that needed to be completed during the two days we spent in Stonyford, CA. We will continue the breeder sampling through the month of February and into March until we visit all 16 beekeepers participating in the project. Click on the pictures below for a description of what was going on in each.
