While this is exciting, I can't help but notice- Under the conditions of the common beekeeping practice in non-tropical regions, which are characterized by high colony densities, prevention of swarming and periodical mite control, it seems difficult to achieve a more balanced host-parasite relationship. Thus far, a long-term survival of A. mellifera colonies without any control measures is nearly exclusively reported…

>It would be nice to see more attention paid to the well-being of native pollinators, which already take care of themselves in regards to parasites & diseases. There's a second avenue which is the treatment-free solution practiced by some beekeepers. The idea there is to keep the selection pressure and just out-evolve the parasites. Given that managed bees reproduce much more often than natural populations there's a…

Thanks for that link, lots of interesting stuff on there.

For anyone interested, (one of?) the way that this selection pressure manifests is in grooming behavior: https://www.youtube.com/watch?v=BWMSIbeKoFQ The trade-off is less honey production and slower comb building.

Using wood bleach was certainly not a panacea, it will be another tool we use along with tossing in powdered sugar. We can cycle through the various treatments but it is a losing war. This may allow commercial beekeepers to start using lithium chloride or oxalic acid. We will see if it gets abused.

The article talked about Lithium Chloride. Where do would bleach and oxalic acid come in?

This is great news, but I have a few questions that weren't covered in the article: 1. How long-lasting is the effect? How long does the LiCl stay "active"? Will bees need to be fed this at a regular cadence to keep them mite free? 2. Is there any evidence on whether or not the LiCl makes its way into the honey produced by treated bees? LiCl can affect the nervous system (although this is an extremely low quantity).…

1. How long-lasting is the effect? How long does the LiCl stay "active"? Will bees need to be fed this at a regular cadence to keep them mite free? The paper says that a single feeding achieved good results, though worse than continued feeding spanning a few days. It seems then that a single treatment will only kill mites that are already in the hive, but will not do anything to help develop immunity. Looks like bee…

I would guess that a small amount would get in the honey the bees were making at that time, but beekeepers would not harvest that honey. When many flowers are blooming, a second box is added to the hive just for honey( a super). At this time the beekeeper does no additional feeding.

Thanks, I reworded it it for clairity, on mobile :/

It would be nice to see more attention paid to the well-being of native pollinators, which already take care of themselves in regards to parasites & diseases, but whose numbers have been falling in recent years. I imagine that the reason this isn't done is because it's not in the interest of Big Ag's medium-term profits.

Perhaps- native pollinators may be impacted simply by "big ag" techniques, pesticides, or fertilizers, in which case changing practice to care for them is surely seen as burdeonsome, annoying, and impacting profits.

Or, it may be that native pollinators are simply invisible. In other words, they won't know what they've got until it's gone.

Where are they not allowed oxalic?

Broodless bees are worth treating and it provides a great knockdown at a time varroa are vulnerable. But bees aren’t broodless most the time or necessarily any of the time. It’s far harder to treat brood and that’s the key area as it’s where the varroa are.

Most treatment see the honey supers removed to avoid contamination. There are a few exception which don’t require this, like oxalic acid.

When the honey flow starts, you need to add boxes fast - I’m up to 7 and 2 of those have been removed, extracted and put back on.

Only doing a single feeding seems like a great way to breed resistance in the mites.

Broodless bees don’t need treating for long with most treatments - it’s the brood that’s hard to hit. That said, avoiding resistance is important.
