Thanks Peter for bringing the 15% mortality up. I keep questioning the 15% as the red line drawn in the sand. My question is "is it expected that bee mortality to be the same across the world including northern Canada, southern USA or European countries?". Why we stuck with this number 15%  as a global acceptable colony mortality?



These questions are quiet important to express colony health. This number should be established for each region and even for each operation based on region, management, and pests. The same concept should be applied, would you like to take colony mortality in the fall by culling out questionable colonies that will not make it through the winter? The other alternative is to  leave all colonies out there and take your mortality in the spring. Don't you love comparing apples and oranges in the new age of beekeeping?
