More Than 40% of US Honeybee Colonies Died In a 12-Month Period Ending In April 220

walterbyrd writes: The Agriculture Department released its annual honeybee survey Wednesday and it doesn't look good. More than 40% of U.S. honeybee colonies died in a 12-month period ending in April. While the precise cause of the honeybee crisis is unknown, scientists generally blame a combination of factors, including poor diets and stress. Some bees die from infestations of the Varroa mite, a bloodsucking parasite that weakens bees and introduces diseases to the hive. Environmental groups also point to a class of pesticides known as neonicotinoids. In April, the Environmental Protection Agency said it would stop approving new outdoor uses for those types of chemicals until more studies on bee health are conducted.

      My parents have a small bee farm. They lost their colonies... Because it was too cold of a winter this year, and they froze.
      Global climate change, as created a lot of atypical, and more extreme weather conditions. I doubt there is a single issue, but a wide set of issues. I know it is complex and hard to put in a headline, so you vilify someone. But reality is there are not so many villains but the actions of many people. Often a combination of good intentions.

        Someone else covered this but is buried.

        Bee colonies do not freeze in the winter. They starve.

        We've been keeping bees in North Dakota, which is colder than wherever you are, for 7 years. All 3 of our colonies survived last winter. One is strong enough that we've split it this spring to try and prevent a swarm.

        The way that bees operate in winter is amazing. The bees form a sphere, with the queen near its center. They vibrate their wings and bodies to create heat. The bees on the outside of the sphere obviously lose heat the fastest. The bees on the inside stay the warmest. The sphere of vibrating bees constantly turns itself inside out, over and over, so that the cooler outer edge bees return to the warm core and replenish their warmth, while the warm bees from the core circulate out towards the edges after they've recuperated.

        This consumes lots of energy (and food).

        As the cluster of bees does this, it moves upwards in the hive, consuming stored honey.

        When they get to the top of the hive, they stop migrating. If they run out of honey, they die.

        We use 2 deep supers and 1 medium honey super to over-winter our bees.

        • What's a super?

        • If they run out of honey, they die.

          ... unless you feed them. My mom is a beekeeper, and we always had a few hives while I was growing up. We would periodically put a feeder jar of sugar water in the hive opening starting in January or February. The bees prefer honey, so they will leave the sugar water alone until they are low on honey. Once they start aggressively eating the sugar water, we knew they were out of honey, and would switch to daily feedings. We also packed straw around the hives for insulation.

          • by bmajik ( 96670 )

            Totally agree. We put feeders on the hives in late winter / early spring for the same reasons. It's especially important here since blooming can be so variable.

            my point was - bees don't freeze in winter, they starve.

      • All you're saying is your parents are bad at beekeeping, sorry. It's called "anecdotal" evidence for a reason - it is solely your own. The reality is most people aren't as bad at beekeeping.

        Complete bullshit is right! How is it that some regions that use neonics are not suffering any bee colony deaths at all? Australia is one of the heaviest users of neonics, yet their bee colonies are quite healthy. Canada's prairies also use neonics, yet their bees are doing absolutely fine. Neonics were in use for 15 years before these bee colony deaths began to appear. Certainly not very much correlation at all between usage of neonics and bee deaths. It's quite likely that the real culprit is the varroa mite, and the bee viruses it carries. The mite has become a serious problem in both the US and Europe, and the spread of the mite correlates much better with the spread of CCD.
        • Australia uses the neonics differently, as I recall. Something about the way they spread the pesticide makes it less likely to interfere with bees.

          That said, it's an insecticide. It's meant to kill insects, and they're generally pretty indiscriminate. It's also fairly likely that even if it's a sub-lethal dose for bees, it's a lethal dose for different beneficial insects.

          I think there are multiple causes--varroa mites have been around for decades without causing such widespread colony collapse. We've got a changing climate and agricultural monocultures, as well as stress from neonics (which it turns out honeybees may prefer over non-treated nectar).

          Looking for single causes is usually hopeless. But we can control our use of pesticides, so it's one of the things on the chopping block. One way or another, we have to bring this problem under control.

            In Australia and western Canada, neonic-coated seads are typically placed in the ground via a gravity-fed metering system (box drill), or via an air drill that blows the seed into the ground behind shanks that open the soil. So dust particles laden with neonics get buried in the soil where bees won't be exposed directly to them. In the midwest US and eastern Canada, where the crops are predominantly things like soybeans or corn, they use vacuum planters which suck the seeds from storage one at time and drop them into the ground. Unfortunately the vacuum planters blow a lot of dust from the seeds into the air. So neonic-laden particles get blown everywhere and we know they affect bees and any other insect. So it could very well be that widespread use of vacuum planters is a part of the problem. Unfortunately air drills don't work very well for row crops that do best with rows of singulated seeds.

            The Alberta Bee Keepers Commission refuses to back any attempt to completely ban neonic use in Canada as it would decimate their industry. Fewer crops means fewer bees are required by farmers.

            The reason neonics are used is that when the plant is young, the neonics are taken up through the plant and make the plant toxic to pests that would eat the little leaves, killing the plant. On one of my dry bean fields last year was seeded without neonic seed treatment, and we did see some yield reduction from pests eating the plants at an early stage, including from works eating the shoots underground. If there's a chance neonics can be used safely, then for sure they are a huge benefit.

            There is the other issue of neonics present in the pollen, leading to bees getting a bit of a buzz. It's not clear to me how much neonic there is in the flower at that late stage of the plant's growth, or what the consequences of that are. Bees around here are heavily used to pollinate hybrid canola, all of which was treated with neonics. So it's really hard to say what the consequences are.

            It's true we can control the use of pesticides, and we should and do. This doesn't have to mean an outright ban. A complete ban would mean the return to more toxic insecticides being sprayed at more regular intervals on a crop, which none of us wants.

          Your argument doesn't really make sense, as the same arguments you've used against neonicotinoids applies to varoa mites.

          You claim that neonicotinoids can't be to blame because there are no large scale bee deaths in places where neonicotinoids are used. Well guess what? there are places in developing countries where neonicotinoids aren't used for cost reasons, the varroa mite still exists, and that also don't have the problem.

      It's not proven that any particular pesticide or agro-chemical is to blame. The fact that urban bees are thiving [treehugger.com] in cities such as Paris and London, despite all the pollution in those environments, is inteesting. One mooted possibile reason is that cities have lots of different species of plants in their gardens and parks, blooming at differing times, so that there is always nectar available from some of them. In the countryside by contrast, with modern, vast, single-crop farms, it may be that there is only one species of plant in the bees environment, and once that crop finishes blooming, in sometimes a pretty small window of time, there is no more nectar. So it could be farming practices and lack of rural biodiversity that are to blame, at least in significant part.

        In Alberta, where there are more commercial bee keeping operations than anywhere in Canada, of honey and other types, and where neonic use is higher than in many other places. Bees are simply are not having the problems seen elsewhere. The bee keepers association here in Alberta is strongly opposed to an outright neonic ban because it would severely hurt their pollination and honey business. Without neonics there would be a lot less Canola and other crops to pollinate.

        Now, this isn't to say that neonics aren't a big part of the problem of bees dying elsewhere. It could have to do with how the neonics are being used. In Alberta they are used when treating the seeds with fungicide, and typically they are placed in the ground with a gravity-fed drill, or an air drill that blows them into the ground. So all the neonic residue gets placed under the soil. In other places, they use vacuum planters (corn, soybeans) which blows neonic-laden dust into the air. So it could be this that contributes to the problem.

      • > It's not proven that any particular pesticide or agro-chemical is to blame.

        The evidence is pretty damning. Neonics do not directly kill, they affect the nervous system so the insects can take care of themselves. Many bees leave the hive, and cannot find the way back. That is exactly the way neonics would work.

        > The fact that urban bees are thiving

        Because they are pollinating crops that are contaminated with neonics.

                Son of a former beekeeper speaking here.

                In summer, a typical worker bee lives for about 6 weeks. 8 weeks, maybe 10, if she has one of the rare posts of guardians at the bee colony's entry, or is one of the even fewer bees that feed the queen. Bees literally work themselves to death. The replenishment rate is, during summer, 100%; this is taken care of by the queen. A typical bee colony has between 10,000 and 40,000 bees in high summer, then goes into winter with about 1,000 bees, clumped around the queen to keep her warm, and comes out of winter with 400 to 600 bees. We are talking about apis mellifera carnica here, the so-called Italian bee, which is the variety most commonly used by beekeepers.

                An entire colony dying in spring or early summer is, normally, an extremely rare event, and indicates either an epidemy, or severe poisoning. Varroa mites are a known cause, but are a largely contained phenomenon now, at least in professional bee-keeping circles. What remains, is ... poisoning. Neonicotinoids or something else.

    We've seen strange swarm behavior here in Southern California the past two years. Anecdotes follow:

    Last year, we had a swarm that probably lost its Queen (or didn't have one to begin with). They maintained a big ball in the tree for nearly four months, gradually all dying off. They made no honeycomb, just a few weird strands of propolis. In the past, when swarms failed to form a new hive, they didn't continue to go and harvest pollen and function like a hive, but all died off much more rapidly.

    This year, we had a swarm ball up in a tree mid-afternoon. They hadn't found a hive by the next morning. By the next evening, they were all falling to the ground and writhing as if poisoned or something. By the second day, there were just heaps of dead bees all around the garden.

    I don't claim to be any expert (although my Dad kept several hives when I was a kid). Still, I haven't seen this before. I don't know the cause of either phenomenon.

  • I just watched some PBS show that led to some conclusion that they did identify what was causing the populations to die.

    TFA says otherwise.

    And I just lost a colony two months ago--it was weird and I sent some in for analysis. Just a pile of bees at the base of my fruit tree...just looked sad.
