Studies link pesticides to plunging bee populations

A widely used family of pesticides may cause bees to lose their homing instincts and hinder the survival of their colonies, European researchers reported Thursday, suggesting that governments should re-examine their use.

A French study used tiny radiotransmitters to track honeybees as they left and returned to their hives and found that many of them failed to return after being exposed to non-lethal amounts of one pesticide.

British researchers, meanwhile, found that bumblebee colonies exposed to common levels of another pesticide from the same family grew more slowly and produced nearly 85% fewer queens than non-exposed colonies, "which clearly could have very strong implications for bumblebee populations in the wild," co-author Dave Goulson said Thursday in Paris.
"I would suggest that there is a need to urgently re-evaluate the use of these pesticides on flowering crops," said Goulson, a biology professor at the University of Stirling in Scotland.

The studies released Thursday are the latest to point to neonicotinoid insecticides, which are often used to treat seeds for cereals and some flowering crops like corn, as a factor in plunging bee populations. The chemicals mimic the effect of the tobacco ingredient nicotine, which is used as a natural insecticide, and pose less risk to humans and other mammals.

Both papers are being published in this week's edition of the peer-reviewed journal Science.

The research is an attempt to understand the phenomenon known as colony collapse disorder, in which beehives fail to survive. Bees pollinate about a third of U.S. food crops, so the sharp die-offs that beekeepers began to report in 2006 pose a high risk to farmers, according to the U.S. Department of Agriculture.

Mikael Henry, a researcher at France's National Institute for Agricultural Research, said honeybees exposed to a non-lethal amount of the pesticide thiamethoxam "had a probability to disappear away from their nests in much greater proportions than non-intoxicated honeybees."

"Honeybees intoxicated with small doses will just get lost and are not able to find their way back home," Henry said. When he and his colleagues used a mathematical model to project the loss rates, they found that colonies would undergo "a marked decline within several weeks," he said.

That leaves the hives vulnerable to collapsing "if there are other stresses in the environment, such as parasites or climate changes or a loss of natural food resources," Henry said.

Thursday’s papers mark the third time research has tied bee deaths to neonicotinoids in the past month. An Italian study published in the American Chemical Society’s journal Environmental Science and Technology suggested that particles thrown off by seed drilling machines can expose bees to high levels of neonicotinoids, while a study led by Indiana’s Purdue University found the insecticides in pollen collected by bees from corn and other plants.

Regulators in France, Germany, Italy and Slovenia have imposed tighter rules on the neonicotinoids in recent years. The USDA and the Environmental Protection Agency say chemical pesticides are one of several possible suspects behind colony collapse disorder, but the EPA says it is in the process of re-evaluating all neonicotinoids.

“We believe that developing revised risk assessment methods will improve our understanding and strengthen the scientific and regulatory process to protect honeybees and other pollinators,” the agency said in a statement to CNN. “EPA is also engaged in national and international efforts to address the potential impact of pesticides on pollinators.”

Thursday’s studies will be part of that review, the EPA said.

Attempts to contact the manufacturers of the two pesticides used in Thursday’s studies - Bayer’s imidacloprid in the British research and Syngenta’s thiamethoxam in the French paper - were unsuccessful Thursday.

    I say we need to stop using nicotine pesticides, give the bees little nicoderm patches and let nature take over. If we don't we'll soon have them trying to bum smokes, maybe moving on to hard drugs, it could be havoc.... Yeah I know, stupid. Like us messing with what's been happening naturally for millenia.

    Do your bit. Stop using pesticides and herbicides, use organic alternatives if you really need to. Plant a bed with insect freindly plants. Provide shelter and food sources. Without bees there is a good likelyhood we all starve.

    Ask any responsible gardener and they will tell you to NEVER use pesticides. Most pesticides are designed to hit the neuro center of the bug and essentially they stroke out and die. It doesn't matter if it is sprayed directly on the bugs or if they land on a dry treated leaf. Everything that touches it will die. One such product (and not the only product) is called Safer. It is sold as a "safer" alternative to pesticides. Safer as it a human can eat the fruit/veg by just washing it off whereas bugs die by droves. It was never designed to be safe with the environment. Sadly, this is a small potato compared to the chemicals used in the farm and fruit orchard situations. Here's the really bad part... We grow such genetically modified plants that they have less protection from bugs yet yield like crazy. Gardeners, save our earth. Go back to planting grandma's heirloom plants and combat pest infestations with beneficial "pests". Aphids? Go to your local gardening store and buy some lady bugs and let them loose. Oh the carnage... That and they are native to most if not all of the US thereby not upsetting the balance nor introducing a non-native pest that in turn can cause bigger problems. Go heirloom and go organic.

    The problem in America...those men who think they are God, figure we are too stupid to appreciate pesticides and pink slime so why tell us about it? This is what is driving our country into 3rd world status. Why can't there be 1000 meat packing companies instead of 10? Cause Regan said it cost too much to employee Americans to work for the USDA we should let them work on the honor system. There isn't a chicken God made that has a breast big enough to slap someone with, so why mess with them when no one eats it. Go buy a bad of tyson chix breast and cook it, any way you please, its going to be rubbary and chewy. But go to your local farmer and buy one, its the best tasting chicken ever. No instead of America being divided on race which is why the media keeps it going, so you don't pay attention to who is really to be feared.

      every domestic animal is genetically modified. whether under a microscope or blind by mixing gametes in a chosen mating. much of the fruit you eat is created by hybridizing plant species. man has been doing this for thousands of years. ever seen a wild nectarine? they don't exist.

      fanaticism and conspiracy theories are hurting the environmental cause.

      GMOs are not killing the bees. the chemicals put on them are—Round-up Ready soybeans are benign, the Round-up sprayed on them is toxic. ban the round-up, and forget the bean.. focus on the real and provable dangers rather than wild conspiracies.

      the idea of creating a plant that you can dump poison on is a bad idea. not because of the plant, but because of the poison. the plant is harmless, the poison is poison.

      don't be such a fanatic. it does your cause more harm than good.

      hives have been collapsing in Europe as well. in fact it was first noticed there. it was French scientists who discovered the link to systemic pesticides made by Bayer. Bayer is a German company not an American.

      the unfortunate part is the situation pits the growers against the bee keepers. if the pesticides are banned there is billions lost in production due to pests and if not, bees die and billions are lost in production due to lack of pollenation. lose, lose.

      environment first is my opinion, but the moment you try to make a blanket conspiracy, you hurt the just cause.

In all honesty, we should be trying to grow as much of our own food as we can in our back yards, but some can't (like me, I live in an apartment) So try to buy from local farmers. Go to farmers markets. It's not only better for your health but it will work America toward a better economy that isn't run by the corporations, but by to the people.

    I live in Australia, where we have no CCD, but have been using neonictinoids for decades – we also don't have varroa mite, which is what has been shown to kill the bees (I've had it explained that it's like flying around with a parasite the size of a dinner plate attached to your back!) I don't know if the chemicals have lowered the bees' resistance to varroa, but they banned neonicotinoid use in France 8 years ago & they still have CCD (& varroa.) So the evidence on CCD & neonicotinoids is not clear at all.
    The key is to not spray them when bees are around – these are insecticides & bees are insects – all this study proves is that insectidies affect insects. Duh!
    We need to look after our bees through careful use of insecticides, even "friendly" ones such as pyrethrum, as they will all kill bees.

    Noticed dozens of bumble bees in my garden today but not a single honey bee. I do not believe that it is the insecticides.
    While insecticides does kill insects, agriculture has significantly decreased within the last twenty years. This problem seems to be exclusively for the honey bee at a time when less insecticides are being used compared to twenty or more years ago when there was plenty of honey bees and bumble bees.

      Silent Spring is nothing more than liberal alarmism. Do your homework on DDT. It has saved millions. Hell, our GI's lathered themselves in it. Judge Edmund Sweeney found DDT posed no carcinogenic hazard to man, nor pose a risk to fish, birds, or other wildlife.

      March 30, 2012 at 2:33 am |
      • Kay

        In case you hadn't noticed, times have changed in the 40+ years ago since Sweeney gave what he then believed was an informed decision. There's been more research. More data collected. As a result, there now *is* evidence that DDT causes both liver and pancreatic cancer. And, yes, while DDT is extremely effective against mosquitoes carrying malaria...they quickly develop a resistance to it, so it makes far more sense to not be entirely dependent on it.

        As far as troops slathering themselves in DDT...that was then, when they didn't know any better. Hard to use that example as a basis for...well, for what? Doing something they now know can be hazardous to their health? Since the hazards include a major negative impact on male fertility, I'll bet our GIs would think twice about bathing in DDT nowadays :-)

    If you want to look at the REAL problem facing humanity and our planet... it boils down to this:

    #1. Overpopulation. There are just *too* many babies being born. Our planet can *not* sustain the food needs *AND* the chemical waste (pollution, etc.) being generated by us, while at the same time rampant deforestation, etc.

    We need to limit people's breeding. Once you have one child, anywhere on the planet, you are sterilized. Period. Generations will start halving, and eventually we'll get down to a good population again (like, 1 million humans, tops).

    March 29, 2012 at 9:05 pm |

      I certainly agree with you that the world's most serious problem is overpopulation. Ironically, the more intelligent breed less which guarantees nothing can reverse the self-destruct course that the human race is on.

      Completely true but it goes against governments need for a tax base. The less people there are the less tax revenue politicians have to do things like, fund studies that dispute obvious fact. Plus the corporations that sell us useless mass produced crap have less people buying their products. It is the catch-22, lower population does not equal economic growth but over population equals a really big mess called the collapse of civilization. Tough call but I agree there are too many people on the Earth.

    March 29, 2012 at 7:52 pm |
    • RetLaEnvEmp

      Organic plant foods requires pollination by bees. The "natural" fertilizers or crop losses from insects, plant diseases, and poor growth due to drought or cold/hot weather are poor excuses for using "organic" farming practices. The bee problems are not solved and food shortages are created by using old and outdated agriculture methods. Organic makes about as much sense as killing off 80% of the human population and going back to a rural farm based agricultural society with no cities using horses and mules for transportation and to pull farm machinery like the 1850's.

      • Fomiak

        I believe the article is trying to say that pesticides are linked to a declining bee population. Pesticides are not used in organic foods. Therefore, if you buy organic, you'll increase demand on farms that use less pesticides, thus solving the declining bee population. I believe that's what lori rose was trying to say. I don't know what your point is, but I don't see a reason why we can't lose select at least 50% of world's population and still enjoy the same comforts of living that we currently experience.

      You are wrong. The research about the mites and fungus was funded by tobacco companies. The researcher never looked at the effects of pesticides. Newer research indicates that even minute amounts of these particular pesticides lowers resistance in bees, making them susceptible to those fungi and mites, which have always been in existence but have never before caused a problem. These nicotine-based pesticides are somewhat new, however, and very profitable for tobacco companies.

    The problem with relating these pesticides to CCD is that CCD has been occurring sporadically for over 100 year, predating the use of synthetic nicotines. It's still somewhat interesting, because natural nicotine was in use as an insecticide that long ago, but the correlation with CCD doesn't seem to hold up well.

      The studies are both unchallenged after peer review. And prove a direct causal link between these chemicals and honeybee and bumblebee behaviour in realistic life scale experiments. There may be other causes of global declines in bee populations but this is likely to be a contributor.

      You're confused. Using plain nicotine is totally different from using the NEW as in NEO-nicotine, systemic nicotine pesticides (think, how long have we had Frontline for dogs vs. using flea collars). It is systemic, it remains in the system. It is new, not 100 years old.

    "Well the bees are disappearing." "They're not disappearing, they're just going home!" "Are you saying bees are aliens?" "Don't be daft! Not all of them."

    *sigh* This is about the 20th different thing that one study or another has found to be responsible for the decline of bees.

      These studies are pretty conclusive and follow on from earlier smaller studies.

      Hey LowIQ, if Monsanto tries to blame the collapse on cell towers again, are you really going to believe them?

      @Jeff – Good one. LowIQ is right! People just don't get what it means when three independent scientific studies in three different parts of the world come to the same conclusion. I have believed all along that this would come down to pesticides. Monsanto is going to be the death of us all with their cursed sterile seeds, systemic pesticides, and GM crops.

    I am shocked and amazed. Who knew human activities would have something to do with it?
