I was just wondering today about how much we may be spreading whatever is in our colonies amongst our colonies while transporting them long distances on semis and under nets.Bees must end up going into colonies other than their own while in transit. Don't you think?
How can the bees on a semi, that are out of their hives, under the net, possibily find their way home, back to their original hive? I guess that hive odor would clue them that they aren't in the right place, but certainly they don't orient themselves while traveling down the highways. Or, at least I can't imagine that they do.
So, let's say that they do end up in some other hive than their own. Wouldn't that spread from one colony to another pests (SHB, Nosema, and Varroa), viruses and diseases?
I wonder what it would take to keep each colony self contained w/out killing it through heat build up? Could it be done practically and affordably? Is it necassary? Would it help lessen our losses?
