Reading the literature on CCD is rather boaring, mostly because it is mostly too academic, that is, hard to follow and produces no results. Rather than try to figure it out I think it might be easier to ask some general layman questions for the same in return.
The thing that catches my interests and doen't seem to be being properly addressed is how robbers will wait up to 3 days to enter a collaped hive. This certainly suggests the presence of a disipitating toxin but none seems to have ben found. It sems to me the robbers must know something we don't.
My first question is, has anyone emclosed fresh bees or robbers into a just collapsed hive to see if anything happens?
I recall reading that feral hives will abscomb from a cavity nest after just a couple of years occupancy and their is no real known reason why they would do this. Is there any information on how old the woodenware is in collapsed hives?
