Edit: "Treatments every week killed more mites than treatments every two weeks, which killed more mites than treatments every month... The only treatment schedule that effectively suppressed mites over long periods was once per week... sugar dusting has been found to significantly reduce adult mite populations at times when little brood is present."
There currently isn't a effective treatment for varroa that doesn't also kill the hive. It is not a solved problem, and there is certainly room for more research in this space.
The article you linked lists a bunch of downsides to powdered sugar: it doesn’t kill the mites it just encourages the bees to brush them off, it has reduced effectiveness when it’s humid, it doesn’t work on mites that aren’t actively on a bees body, and it has to be applied regularly.
The hard truth these days is that the work of bee keeping is like 80% keeping the mites in check. Plus all current treatments render the honey inedible so you can only do it at the end of the season.
To add, varroa quickly gains immunity to the pharmaceutical treatment we have, so the same medication cannot be used 2 years in a row. Most popular treatment from late 90s that used to kill 99% of varroa is now completely ineffective.
It was explained to me this is well planned and solved in Czechia. Varroa treatment is refunded my the government, but only one type of medication every 6 months. It's cheaper for beekeepers to use whatever the government gives them for free, than use something else. And the medication is free only for a few weeks, so everyone will use it at the same time.
Depending on location acid treatments can only be done after the honey harvest anyway, due to temperatures, so it's a minor issue.
You can also use drone frames, and remove drone brood during the summer, or cage the queen a period of time. These are both mechanical treatments and obviously doesn't hurt the honey.
And, by the way - natural pathogens exist in just about any population. These very, very rarely led to extinction. There is a media trend to claim the mites are at fault. This reminds me of prior fault yielding e. g. "mad cow disease" - and then the media also stopped doing any further investigation at that point. It's as if they have break points where you can not go past those points. Now it is the mites that get blamed.
There is a valid point though. All types of insects are in decline, but the decline in bees is exclusively due to varroa? It's not unreasonable to assume that at least part of the decline in bees is due to the same conditions that results in less butterflies, beetles, dragonflies and so on.
The removal of habitats suitable to insects and modern farming certainly plays a part as well.
Honeybees deal fairly well with pesticides, wild bees doesn't[1], but none of them can deal with losing habitats.
You can interpret what is being said charitably, as some true claims surrounded by nonsense. However, this says more about your model of the world than it does about the intentions or beliefs of the author. The phrasing and the argument structure suggests that to me this is the same belief cluster that supports COVID denialism and the idea that it is possible (perhaps desirable) to evolve immunity to arbitrary diseases via a "natural selection" let-the-weak-die eugenics.
Your response is analogous to how people project onto vapid AI slop meaning which was not present in the process used to generate it. The primary difference being that there is a true meaning behind these words, something against which we can compare your reading. (I would like very much for your reading to turn out to be closer than my reading to what shevy-java intended to say, but I do not expect it.)
It is great and currently necessary we use them the way we do. It makes one wonder in the age of AI and evolving farm practices, can we start finding ways to cultivate already-climate-adapted native bees to do the work? Can we leverage adaptations for specific crops?
I get it that honeybees work great at pollinating monoculture fields, etc., but that does not change the fact we are perpetuating a square peg in round hole problem and pushing it very very far right now, at greater and greater cost, all while climate change is fighting us.
I suppose honey bees are not native in North America pretty much the same way as the human species?
I don’t quite understand why there seems to be a pretty persistent thread around “honey bees are invasive and harm the ecosystem by stealing all the food from the native bees and doing all their pollination; that’s why they decline” - when at the same time the use of pesticides is so rampant that insects are literally gone entirely.
Honey bees are not great and reliable pollinators btw.
So the solution is: more genetically modified crops? More pesticides?
Unless “we need to stop our use of pesticides and we should also acknowledge that honey bees are an invasive species and consider making changes to the way we do monocultures” are in the same sentence this entire “honey bees are invasive” argument just feels super weird. Pesticides kill native pollinators. It’s not the honey bees.
Edit: and just to be clear - honey bees do not survive in the wild by themselves anymore due to varroa mites. They essentially depend on humans to protect them. That’s what the entire purpose of this article is about. So, if humans stopped keeping honey bees - they’d have a pretty hard time surviving in the wild on their own.
An idea that sprang to mind and please point me out at which points its unrealistic and why because I am talking completely out of my ass here. If we want to reduce mono culture but we still need to somehow figure out how to provide humanity. Could large scale vertical farms, in Green Houses reduce the footprint of monocultures? By being more productive year round? Or is that just technolgist delusions of mine?
Another innovation I see is the use of "crop tunnels" (https://en.wikipedia.org/wiki/Polytunnel) to greatly extend the growing season in colder climates (another poster mentioned "Ohio"), and/or better control evaporation.
The thing that always baffles me with vertical farming is sunlight. Assuming most crops are pretty good at turning full spectrum sunlight into useful stuff, why shrink your solar energy per crop?
And assuming you get around this via grow lights, surely the energy and material cost goes up too much for high-volume crops to make economical sense.
I think it's hard to generalize whether vertical farms are good or bad; efficient or inefficient. It seems that whether it works or not relies very heavily on the locality.
In my part of Ohio, we have lots of farmland -- and plenty of water that just falls out of the sky. We've got reasonably-long, generally-hot days during our growing season and we get some serious crop production done here while it lasts.
The rest of the year? The days are short. It's dark and cold outside; frozen, even. We can't grow crops outside here in the winter.
But vertical farms (eg, fancy greenhouses) can just keep going. With artificial light and/or supplemental heat, they're still producing even in the depths of winter.
Thus, I can go to the grocery store near my house and buy a locally-grown tomato in February. It's expensive to get this done, but the alternatives include paying someone to drive it up here from thousands of miles away or just going without a tomato until after things have warmed up again and stayed that way for awhile.
This only makes sense in certain circumstances I think. For example, shipping tomatoes from 5000km away when it's winter in Canada.
I recently did some research, and there are multiple local greenhouses around many large Canadian cities for just this reason. They are competitive in the winter, and sell to local supermarkets. The cost of the greenhouses vs shipping + loss.
And there is a loss in nutrition, when you harvest green and it takes weeks to hit the table, vs something picked yesterday and picked when actually ripe.
Of course, these are large warehouses, not typical greenouses.
So I guess the answer is, it can make sense in certain circumstances. A warmer place where you can grow fruit outside year round, not so much.
Over the years, many firms have poured many $millions into vertical farms.
If you're growing extreme-value crops - marijuana, or maybe exotic salad greens for Michelin-starred restaurants - that can actually work.
Otherwise, you're trying to compete with millions of square miles of naturally sun-lit dirt, and extremely efficient modern agro-tech stacks. Bankruptcy awaits.
> just technologist delusions of mine?
I'd bet you've read several articles about techno-utopians setting up vertical farms, and their grand dreams. Which always hand-wave the "how can this massively expensive setup complete with dirt?" part.
Farming sun-lit dirt does not magically require monoculture, nor poor farming practices. The problems is monoculture's appeal to certain human cultures - especially profit-maximizing "big ag" capitalists - and the agricultural policies enacted by naive politicians.
The catch is that native North American pollinators are adapted to native North American flowers and have a great deal of difficulty pollinating introduced species that are native to Eurasia. Given the vast majority of commercial crops are not native plant species, the only way to mass pollinate them is to use non-native pollinators.
Also, few native North American bee species are eusocial. That's another quality one would need to be able to use them the same way as commercial honeybees are used today.
GMO hyper competitive feral cat colonies that ignore birds and pollinate gmo soybeans whilst collecting for their kitten hives. Each claw is of course a stinger. What could go wrong.
You could pick up a catalog from any of these places and find half a dozen different species of bees to cultivate for pollination. Blue mason bees come to mind. Anything that's even slightly domesticatable is being pursued. Some of these bees are loners too, perfect for the hipster crowd.
Amusingly, propagate has a horticultural, and non-horticultural meaning, and it's not obvious which one you're using there, because the bee's role is long over by the time the seed is ready to go out into the world.
Pollen can be carried (as noted by sibling and you) by lots of different insects, and there's myriad solitary and other (by conventional standards) weird bee species around, plus lots of plants are happy to pollinate themselves (tomato is a good example) or rely on wind (corn/maize is the famous example there).
When the common honeybee landed in the continental USA, about four centuries ago, the same people also brought in lots of (other) european plant species that had co-existed with Apis mellifera for millennia.
Asian bees are perfectly capable of removing and killing mites as is. So are some breed species of European honey bees. There have been found abandoned apiary in France where the bees have evolved to groom themselves and remove the mites.
The bees does need to evolve, but not to the point of producing venom. Mechanical mite removal works equally well.
I was rather thinking of bees developing the ability to shoot tiny lasers to cook the mites off like popcorn. Or maybe a static discharge from their wings rubbing together, like a natural taser.
Pesticides are bad for bees, but Varroa is too. Until Varroa arrived in Australia the bees there didn't suffer from colony collapse, despite high pesticide use.
It seems that varroa were first discovered in North America in 1987. [1] Glyphosate use at that time was around 4,500 metric tons. By 2014 we were up to 125,000 metric tons [2]. There was an exponential increase coming after 1996 when glyphosate resistant GMO crops became a thing. I don't have an opinion on this topic one way or the other, but there seem to be quite a lot of negative correlates since then, and this is just another one. Of course correlation doesn't mean causation, but you can't completely dismiss it.
Kinda related, but in my house I don’t kill spiders, as long as they are in the corners they can live rent free while cleaning other bugs. Before, one time I went and killed all of them, in less than a week I started seeing sliverfish and similar bugs, I realized I messed up the natural order, so I just keep em now!
Too lazy to read an article that takes about one minute? Sheesh.
> “We screened 50 venoms, mostly from spiders and scorpions, by applying them externally to the mites,” says Herzig.
> “We found more than 75% killed the mites within 24 hours. We selected 2 of the most potent spider venoms for further analysis.”
As article suggest - it is fully biodegradable. I suppose venom has some short half-life. And since peptide is isolated, not full chain toxin, it should be harmless to humans.
The Danish beekeeping association has a list of their top four reasons for declining bee populations (both honeybees and wild bees). None of them are mites. Multiple experiments and analysis of abandoned beehives show time and time again that the bees will develop coping mechanisms against varroa mites if we let them.
All four reasons are linked to a decline habitats suitable for bees.
* Lose of natural habitats.
* Fertilization close to natural habitats causes grass to grow and outcompete bee friendly plants.
* Herbicides are killing flowers.
* Pesticides hurt wild bees (honeybees to a less extend).
What is killing bees more rapidly than anything is modern farming. When you see farmers, especially those in the US, needing to truck around bees it should be abundantly clear that something has gone very wrong. Massive fields and orchards with a single crop is no place for a bee, they simply have no food for the majority of the year. What do we expect bees to do with 50 acres of corn or wheat? To a bee that might as well be a desert.

"The peptides killed only the mites, while the bees survived."
What benefits do these new treatments offer? They certainly won't be cheaper.

Formic acid is one of the few treatments which is acceptable to use while honey is present.

Regenerative farming and/or permaculture offer ways to run industrial-scale agriculture without the monoculture. See i.e. https://peercommunityjournal.org/articles/10.24072/pcjournal...

The there is the issue of honey production.
Neither are horses.
I guess the issue is you don't get honey with the native bees.
The horse ancestor species come from the Americas and migrated to Eurasia over the bearing land bridge.
Horses were only missing from North America for 10,000 of the last 50 million years.
Of all the examples to pick from, seeing GP picked horse made me wonder if GP was doing it for gits and shiggles.
But yes, there are other pollinators like butterflies, moths, flies, birds, etc.
Pollen can be carried (as noted by sibling and you) by lots of different insects, and there's myriad solitary and other (by conventional standards) weird bee species around, plus lots of plants are happy to pollinate themselves (tomato is a good example) or rely on wind (corn/maize is the famous example there).
