Lionel and Waldemar >>I've noticed that very old combs with small cells on them have very high numbers of mites and DWV. Just an observation. Reply: Yes, it is very good for luring the mites to for broodnest cleansing periods, so that the mites can be cleaned out. Have seen whole sheets of worker comb in the beginning cleaned up this way as beekeepers hives all around us collasped. Amazing how the broodnest with proper sized comb acts like a living liver cleaning up disease and parasisitc mite problems with the help of the workers at this period of time each year. After all, why change out old good combs if they are working properly and CLEAN, never having seen treatments! I found the research paper interesting. Question: For now if a lure can be made to smell like old brood combs so the mites can key into them more for an attractant, then does that mean that the phoretic stage will be lured more into the worker cells again, and not dispursed more throughout the colony. I know that small cell can already handle the problem with chewing out of varroa, but can the larger cells that allows for reproduction? Sounds like more internal imbalance somehow. Then with the mites lured back there................. What is the next step for large cell beekeepers? Trapping them somehow? Some new type of bait setup/trap to purchase to add to the arsenal?
