Bees Prefer Nectar Laced With Neonicotinoids 104

Taco Cowboy writes: Neonicotinoids are a class of neuro-active insecticides chemically similar to nicotine. Neonicotinoids kill insects by overwhelming and short-circuiting their central nervous systems (PDF). Shell and Bayer started the development of neonicotinoids back in the 1980s and 1990s. Since this new group of pesticides came to market, the bee population has been devastated in regions where they have been widely used. Studies from 2012 linked neonicotinoid use to crashing bee populations.

New studies, however, have discovered that bees prefer nectar laced with neonicotinoids over nectar free of any trace of neonicotinoids. According to researchers at Newcastle University, the bees may "get a buzz" from the nicotine-like chemicals in the same way smokers crave cigarettes.

        Toss a few gallons of water in your trunk before you head to remote locations -- while the propylene glycol in the antifreeze may not kill you, the corrosion inhibitors and other ingredients plus possible oil and combustion product contamination is not going to be great for you.

          The glycol is the corrosion inhibitor. That's its job as much as anti-freezing. That's why we use it even in climates without freezes, and not just a smaller package of corrosion inhibitors. You have to substantially change the properties of the water to retard corrosion.

            Propylene glycol oxidizes when exposed to air and heat, forming lactic acid.[9][10] If not properly inhibited, this fluid can be very corrosive, so pH buffering agents such as dipotassium phosphate, Protodin and potassium bicarbonate are often added to propylene glycol, to prevent acidic corrosion of metal components.

    Colony collapse disorder (CCD) has been linked in studies to insecticides, pollution, climate change, GMO crops, viruses, fungi, and on and on. Unfortunately, those are merely statistically correlative links and the actual cause of CCD has yet to be determined.

    • by rahvin112 ( 446269 ) on Friday April 24, 2015 @10:33PM (#49549331)

      CCD is likely a multifactor agent. This is the reason it's been so hard to determine. I saw a discussion with bee keepers and the collapse goes like this.

      The bees are fine all summer. When they seal up the nest for the winter and begin to subsist on the remaining stored honey (from what the humans didn't take) somewhere in the middle of the winter the bees start flying off and not coming back. At some point after this has begun the queen dies and no new queen is hatched. (new queens can be hatched easily by feeding one of the larva royal jelly). It's like the bee's suddenly go insane, most fly off into the wild and die, those meant to keep the hive going stop working (such as hatching new queens) and in no time at all the hive is dead.

      They are having a hard time determining cause because their is no clear cause. The insanity thing is a totally new action that's never been observed in bee populations before, outside the wasps that lay larval in other insects brains. So they are examining multiple possible paths at the same time trying to figure out what is causing this bee insanity that's causing the collapse. Neonictids are suspects because they are potent CNS actors in some species, something that could explain the insanity. But it could just as easily be that the neonictids aren't the sole cause, they could be weakening the bees such that they are starving to death in the winter, or there could be a fungus that's attacking them while they are weakened.

      Once they understand better how bee's react to neonictids and perform some controlled experiments with them they will have a better idea if they are the cause or related to it. There is reasonable concern here that the risk of the neonictids isn't worth the benefit's they provide. A collapse of bee's would be catastrophic to plant life. It's not just honey bees that are dieing either, reports are bumblebee's and other species of bee are dieing off as well. There is a real concern right now that there may be whole species of bees that are gone.

      • by Rei ( 128717 )

        Yep. It's wierd because the symptoms can correspond with many different causes. For example, the climate change thing makes sense because bees can be tricked into thinking it's spring and start foraging or even swarming in the middle of winter when they really should stay in the winter cluster. The occasional warm day is good for them to be able to get out and void themselves, but longer periods of significantly fluctuating weather can be bad.

        But it also matches other problems. Diseased or dying hives often

        • The number of colonies isn't a good read, nor the amount of honey being produced for one simple reason. The beekeepers are doing everything they can to keep production level. They are producing new colonies at a breakneck pace. I've been told they've never produced this many colonies ever, the honey producers are literally replacing their entire stock of bees almost every year.

          • by Reziac ( 43301 ) *

            Honeybees are technically an invasive species in North America; they were imported, not native. There are numerous other species, including small native bees, that did the pollination work before honeybees came along. Far as I have heard, populations of these native bees have not been affected by CCD.

            Neonicotinoids are relatively expensive (4 years ago, Imidacloprid was $25/pound, about 5x the cost of permethins), and I'd guess despite being about a quarter of the insecticide market, that in ag they are pro

You're certainly not going to find it used in Montana wheatfields, yet CCD has affected bees here as well... so now what to blame?? Indeed, most of our acreage is never treated with anything, being non-arable grazing land or wilderness. Hasn't helped bees any.

                      Apparently, wheat growers do [growinggeorgia.com] use neonics. Note that one way to use them is to pre-treat seed. The pesticide will persist in the plant for some time after.

                      But Georgia isn't everywhere, and wheat isn't a bee-pollinated crop.

                      The relevant thing is that bees are affected without ever being anywhere near a treated area, in fact without being near an area treated for anything at all.

                    • by sjames ( 1099 )

                      The website was for a Georgia group, but the article was about a national group.

                      Pine trees aren't pollinated by me either, but I can't go outside in the spring without ending up covered in pine pollen (presumably grass pollens as well, but I can't see those).

                      That leaves your relevant thing highly questionable. A re-analysis is in order.

                      I get the feeling you won't be happy until everyone admits your particular point of interest is the culprit, which isn't exactly a scientific method either. It's fine to look at every possible candidate. It's not fine to decide that's the culprit when it's not even present in many regions of interest.

                      Also, if neonics are the culprit, that should be very easy to demonstrate -- you should be able to reliably induce CCD in fairly short order just by isolating a hive

                      I get the impression that you'll convince yourself to believe nearly anything (even that nobody much uses neonics anyway) to 'debunk" an inconvenient hypothesis before it is even tested.

                      I note that you spoke of the "lack of neonic use on wheat" supporting your conclusion like it carried the weight of God's own word. As soon as I debunked that belief, it was sudden

      • Maybe in the Winter they are jonesing for a fix that they leave to find it despite it being winter, and as a result die. Due to all the bees leaving, the hive becomes unsustainable. It could also be that I think bees also provide warmth, if enough leave the rest just freeze to death.

        Drug users from an external observation point of view do all sorts of crazy things to try and get their next fix, particularly when their supply or their ability to get it (money) runs out. Could be as simple as that.
