The cells
of wax foundation in the market is of 5,4mm diameter.
We are using 4,9mm and the bees in nature do it until 4,6mm.
The drone of apis cerana is just the same size as our big bees!!
So the varroa mite confounds the worker bee brood with the drone brood.
In apis cerana, the mite is mostly concentrated on the drone brood.
In the big bee they go to the worker brood and there they multiply enormously.
With the small bees it is quite different: In spring and summer the mites concentrate in the drone brood. The drones are very very important in our small cell hives. They attract all diseases, work like a liver and avoid brood infection of the worker bee. When the hives do not rear much drones in autumn, the varroa has to go to the worker brood, although they do not like it, because they know that they cannot multiplicate good enough there. In this season the bees do not have much to do anymore and they can dedicate their time to other things than brood and honey. They can detect from outside that there are mites in the capped brood cells, open them and get off the mites. They open the cells when the young unborn white bee in the cell has purplish eyes. If the mite is on the head of the baby bee, they bite it and they bleed to death. If the Varroa is at the bottom of the cell, the bees eat the young unborn bee to get to the mite. But the problem is how can we get the small bee? If we add a small cell foundation to a big bee colony they will do a disater.
We have to go step by step.
For
Dee Lusby, arizona, it took 20 years to achieve
it, for me ,with her help,
it was 6 years.
If the bees are able to draw the small cells perfectly,
it is very likely that
they can defend against the varroa mite and to all other diseaese.
(but
we also have to change quite a few things in our hive handling)
This is one of our best hives that is drawing the small
cells perfectly.
The queen is a mother of the queens that we are rearing.
