Spider venom kills varroa mites without harming honeybees

    Honeybees are not native to North America.

    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.

      >>Honeybees are not native to North America.

      Neither are horses.

      I guess the issue is you don't get honey with the native bees.

        A quite similar horse species went extinct in North America ~10,000 years ago likely due to humans.

        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.

      If they are not native, how did plant propagate seeds? Flies? Wasps? Butterflies?
      • EdwardDiego 50 minutes ago
        Native bees. Apis mellifera are introduced bees across most of the world.

        But yes, there are other pollinators like butterflies, moths, flies, birds, etc.

      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.

    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.

      No. The mites are not what is killing the bees.

      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.

        Lotta unsubstantiated claims you're making there.

          The negative government prior is unusually attractive.

    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!

    Some potentially seriously good news there if it all pans out the way it sounds like it might. Fingers crossed for the bees!
    • shevy-java 2 hours ago
      This assumes the mites are what kills the bees. What is that asssumption is flawed?

        Then all the scientists who study apiary are wrong and someone in the HN comments knows better than all of them.

        Congratulations, I look forward to your Nobel prize.

        Nah, it cannot happen that Big Agro's poisons are to fault...
        • niksmather 1 hour ago
          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.
        • EdwardDiego 47 minutes ago
          Big Ag was already using those poisons before varroa, so if it was the cause, you would've seen it manifest before varroa.

    So what's it going to do to the honey? Will we have spider venom laced honey?
    • hyperionultra 1 hour ago
      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.

        I'd imagine eating it has a different effect than having it directly enter the bloodstream as well.

      A lot of people might become allergic to honey, and never know why.

      Probably, but not at any meaningful concentration.
  • shevy-java 2 hours ago
    Still the honeybees keep on dying ...

    Perhaps it is time to stop blaming the mites for the decline of the honeybees.
