Hi all
As I have mentioned, supersedure has been a chronic problem, not recent at all. This is from 1921

We had practically the same experience. There were
twenty-seven queens out of ninety that failed, that is, died from one
cause or another. I presume that you noticed practically every one of
those colonies started to requeen itself.

We found in the case of package bees that every colony, practically,
will start to supersede. We found, for instance, that when bees come in
as early as April 20th, the loss will be from ten to fifteen percent. more
than if the bees arrived on May first. I am just wondering whether or
not we can figure correctly the value of queens that come in packages.

That the queens should be tested out can not be questioned, but if
those queens had not been shipped in, would the results have been as bad?

Last year we got packages about the first of May and we did not lose
a single one, but this year we lost twenty-nine out of ninety. We
attribute that to the fact that when it was cold the bees would not take
care of them.
