Weekend update
In my previous blog, I wondered whether the taller natural comb, irregular passageways and increased brace comb found in undisturbed colonies might act as a debris trap, reducing the amount of material that ultimately reaches the collection tray beneath the screened floor.
Photographs taken yesterday have encouraged me to think more about this idea. This image shows an undisturbed colony where substantial brace comb and wax bridges have formed between adjacent frames. Looking at this architecture, it seems plausible that much of the falling debris is intercepted before it can pass between the frames. Particles may be caught on wax bridges, accumulate within the irregular passageways, or be recycled by the bees themselves.
By contrast, managed colonies are routinely separated during inspections, breaking these natural wax connections. The open spaces between frames may provide relatively unobstructed pathways for debris to fall directly onto the inspection board below. If this is true, then managed colonies may produce larger amounts of collected debris—not necessarily because they generate more debris, but because more of it successfully reaches the tray.
At this stage, I am currently adapting a camera and lighting system that will allow me to observe exactly where debris falls within the hive.
