Nathan, thanks for putting in the time and effort to produce this. I’ve watched Cory’s videos, read the Harbo bee co sight, and assayed a few colonies last season. It’s so helpful to watch him go through a full frame and discuss it. Much appreciated.

I can't wait for the data that will correlate Harbo assay to a UBO assay. I hope that is one of their objectives when Kaira visits him to do UBO assays. It would make the value of UBO assays go way up if you could show that a certain UBO % score = a Harbo score of 4, 3, and 2. Exciting time to be a bee geek.

If it works as hoped: 1. Way faster 2. Will work on treated colonies with no mites because it tests the behavior, not the response to mite pressure.

A theory is with VSH or colonies with another natural mite defense, is that they let mites into drone brood but keep them from worker brood so that the work force and majority of the colony isnt as infected. the drones are the sacrificial lambs so to speak. so many interesting things about drones that we have no idea about. more uses then just mating.

QUESTION: Does anyone do a "modified Harbo score" whereby if you find NO Varroa after 100 worker cells, the breeder assigns the colony a score of 3/4? (Instead of assigning EITHER a 3 OR 4 score) In other words, this would save the breeder the time in searching through another 100 cells. I hope that this makes sense.

@DuckRiverHoney

Yes. If it’s not a breeder queen Cory will do 100 and assign a 3+ instead of doing another 100 to try to get a 4.

I think mites in drone brood may be more inconsistent.

I have a variety of hives that have come from feral swarms, each surviving at least 4 years in the wild. I see ejected pupae occasionally, I presume by the time I'm seeing these pupae the varoa have fallen off/detached themselves. Grafting from the best producing of these hives next year is my next step as I need more than vsh. How do I stop the loss of these valuable genetics to imported and treated drones?

Interesting, do you think commercial beekeepers will ever move to spring treatment with OA to knock down the mites when the more heavily infected drones are emerging? Not part of Harbo but just removing the mites earlier in their reproductive cycle for the year. Drones have been found to move to another colony as early as 3 days after hatching.

OAV is most effective during bloodless times, so I bet commercial guys will continue winter treatments if they’re using OAV.

Nathan, question for you. If the bees uncap a cell to check for mites and they find no mites, can a mite then hop off the nurse bee and go under the large larvae to hide out while it is being recapped? Bees that don't uncap wouldn't have that issue.

@DuckRiverHoney

Жыл бұрын

I suppose so Russell, but the reason they uncap is because they sense a reproductive mite. So if what you suggest happened: 1. The mite may not have enough time under cappings to reproduce. 2. If it did try to reproduce the bees would probably pull it out anyway.

Nonreproductives may be old or sick or weakened in some way? Maybe a foundress mite only reproduces a % of the times she’s under cappings? Maybe some mite strains are more prolific than others, similar to Italian bees vs Caucasian? I’ve got lots of questions and few answers.

@russellkoopman3004

@@DuckRiverHoney I have few answers also. If the mite goes under the cappings she has no food to eat except the larvae. If the mite starts feeding on the pupae then the injury alerts the bees to uncap. So the mite is either on a diet or hasn't had time to start feeding on the pupae???

@DuckRiverHoney

Or the act of reproduction creates a different smell that causes the bees to uncap and check it out?

@Duck River Honey I understand what they are doing BUT if you aren't challenging the bees with mites how do you know it is working. Example, Weavers and other say they haven't treated their bees in a long time. Everyone I have talked to who tried their queens had the hives die when they were challenged with mites. I'm a retired corn Breeder. When I wanted to select for Northern corn leaf blight resistance, if I planted research trials in a field and I didn't have susceptible hybrids planted I had no way of knowing if a hybrid was resistant or just an escape. It seems to me the Breeders should put some mite bombs among their colonies to insure they are challenged by mites. Make sense? Glenn

Bees need to be balance with the mites and mites need to be in balance with the bees. Isolation is an important factor to treatment free, so you’re not bringing in more virulent mites.

I would suspect that it is a pheromone or something that like that that the bees can tell which mites are reproductive.

Maybe the reproductive mite like mated queens emit an odor or pheromone that is not present on nonreproductive mites.
