I was taught my first year to manage with powdered sugar and quickly learned it wasn't enough. It depends. I and all the beekeepers in this area do not treat for varroa at all, and our losses are...

  • Again, increasing the size of the study does not shift the mean, it only decreases the deviation. For instance a study that has 100 entries in it, has a standard deviation of +- 10% and one with 10,000 in it has a SD of +-1%. But the mean will be the same, or only fluctuate within the level of the deviation. One standard deviation gives about a 65% confidence level, 2 a 95% and 3 a...

  • That is especially true if you use an entrance feeder. Inside feeders are not so bad, but can still be a problem. Marshall

  • The law of large numbers does not negate it at all. For instance, similarly studies have shown that more people die in hospitals than anywhere else.

  • If you feed some hives, and not others, then the ones you feed are those that are in trouble for some reason, and the others are healthy. The fact that you are having to feed them is selecting a set of unhealthy hives, those you don't feed will be a set of healthy hives. It is no surprise that the set of unhealthy hives have a higher mortality. Marshall

  • Doesn't that let rain in? Marshall ---In Beekeeping@^$1, wrote : Upper Entrances One method that was mentioned to me years ago was to offset the top super so that a 1/4" to 5/8" opening between the top super and the super/hive body beneath it was provided allowed good ventilation and eash access to the upper part of the hive by foragers. So far I've not observed any problems with...

  • I drilled 1 inch holes in an upper super. They guard it, and occasionally use it, but surprisingly not a lot. It is probably more important from a ventilation standpoint. A couple of my hives were bearding heavily during the heat of the day, one so badly the group hanging off the entrance was larger than the original swarm that came in a couple of months ago. I had standard...
