Re: Eye witness to colony collapse: Bee-farmer loses 2,000 hives in one month
This was the first winter I used this yard for overwintering. I have considered the cold/moisture drain. It sits on a north facing slope, but is wide open to the sun. Bees have done great there for a couple years. I do suspect mites and their virus issues, maybe nosema problems but most of the bees I checked under my scope had no nosema. Survivors in that yard are strong. Since I didn't treat these nucs [on purpose] I believe they got so strong that mites were abundant and took their toll on the winter bees. Guess I need to revisit not treating strong nucs. I have some weak nucs in another yard doing pretty well. I post the results from Beltsville when I get them.
