Re: A-Z Hives - ventilation ?
I think the bees have some sense where the propolization makes sense and worthwhile the effort. Or not.
For example, I am yet to see a documented case where the bees made entire nest out of propolise (like the wasps make theirs from paper).
There are many examples of the bees living out in the open; I myself took down such a swarm - they already had capped brood - right on the apple tree branch.
At the time of removal, they have not started building any propolis walls yet around there nest.
In fact, they never do, to my knowledge.
Why not? Why not just build the entire enclosure out of propolis?
Because it is a very unpractical proposition (a very expensive proposition at that).
I think this has some connection to do with those meshes in AZ hives going.
They are not considered the boundary of the hive - so to invest lots of effort and resources into propolizing them.
In fact, let me guess, the distance from the mesh to the frames is large enough so to remove the mesh far away so it is outside of the perceived boundary of the bee nest.
I say, some 2-3-4 inch spacing between the frames and the mesh will virtually guaranty - your mesh will not be propolised.
The mesh being fully ventilated through is also not really considered a good substrate to attach the combs to (especially removed from the entrance to the farthest possible location - bees just don't like building the combs so far removed from the main entrance way)
The frames on the back of the hive, on the other hand, should logically be well glued to each other - that I don't know.
But obviously the frame woodwork is spread apart far enough on purpose - so the frames are not glued to each other (mandatory for the AZ designs).
