Is there any evidence/statistics if CCD is seasonal? Does it occur more at certain times of the year or not?

Is there any evidence/statistics if CCD is seasonal? Does it occur more at certain times of the year or not?
So, no one knows the answer to this question?
No one even knows what CCD is.
The answer is Maybe. CCD doesn't necassarily follow the same guidelines(?) as Winterkill. But, I don't know if anyone can say how many Winterkilled colonies were actually the result of CCD or CCD related.Quote:

So, the answer isn't black and white. Sorry. Others may disagree.
Watch the BBC movie "Where have the honey bees gone". It describes a few theories about a pesdicide
and that CCD happens more during the dormant period of the bees (I am guessing that means winter)
Could be. But, if what I experienced when my colony count went from 732 down to 100 over a 9 month period was CCD, then it occurs not only in winter, but during the summer and fall too.
When Hackenberg experienced what came to be called CCD, it happened in September/October.
I actually think that may be a pretty fair statement. While there is a definition out there, it seems to mean different things to different people and sometimes becomes a catchall diagnosis. Some beekeepers (myself included) have never seen large unexplained losses where bees suddenly disappear but many beekeepers including some that I think are exceptional have experienced it. A recent experiment that Randy Oliver conducted may have provided the most compelling evidence to me that viruses may play the biggest role. It does, though, seem to be more of a fall and winter phenomena and good nutrition and low varroa mite levels seem to be the best defense against it.Quote:

We don't know what cases CCD; it is likely that many things can cause it, what caused it in one beekeeper's hives may not be what cased it in another's.
At this point it is starting to be just a label that gets thrown around willy-nilly.

The more I read the more I am convinced it is a combination of Imidacloprid and Nosma

yup
