World's No. 1 pesticide brings honeybees to their knees, say scientists
Source: Christian Science Monitor
A team of Harvard biologists has come closer to cracking the mystery of honeybee Colony Collapse Disorder (CCD), eight years after its appearance.
CCD persists in transforming bee colonies around the world into ghost towns: by the end of each winter, some colonies wind up littered with dead bees and emptied of many more, with no signs of renewal.
"One of the defining symptomatic observations of CCD colonies is the emptiness of hives in which the amount of dead bees found inside the hives do not account for the total numbers of bees present prior to winter when they were alive," states the report, published May 9 in the Bulletin of Insectology.
The exact mechanism behind these collapses remains dauntingly unclear, but they have been linked with pathogen infestation, malnutrition, and pesticide exposure. This week's report strongly indicates that two neonicotinoid insecticides that are widely used on crops can decimate honeybee colonies' winter survival rates whether or not mites or parasites are present.

Fifteen countries voted in favour of a ban - not enough to form a qualified majority. According to EU rules the Commission will now have the option to impose a two-year restriction on neonicotinoids - and the UK cannot opt out.
The Commission says it wants the moratorium to begin no later than 1 December this year.
The UK did not support a ban - it argues that the science behind the proposal is inconclusive. It was among eight countries that voted against, while four abstained. . . .
Some restrictions are already in place for neonicotinoids in France, Germany, Italy and Slovenia.

9 May 2014
In April, a landmark European study revealed the UK is suffering one of the worst rates of honeybee colony deaths in Europe. "The UK government [which opposed the EU's neonicotinoid ban] has accepted the need for a national action plan to reverse bee and pollinator decline," said de Zylva. "But its draft plan is dangerously complacent on pesticides, placing far too much trust in chemical firms and flawed procedures."

(36,281 posts)First, the "team of Harvard biologists" is exactly one associate professor in the school of public health. The other two authors are bee keepers, not Harvard faculty or professional biologists. The study was published in an obscure, low impact Italian journal. I've been a working academic entomologist for twenty years and I had to look it up because I'd never heard of it. I'm surprised that a paper claiming to achieve the holy grail of linking honey bee population decline unambiguously to low dose neonic exposure did not apparently pass muster in a more mainstream journal, and I'd love to see the reviewers' comments if it was submitted and rejected elsewhere (the willingness of the Bulletin of Insectology (yup) to publish this line of research back in 2012 might have had something to do with the authors' choice of venue this time). The same three authors published a similar paper in 2012, in the same journal, that is not well regarded by most experts in honey bee health. In this present study, the sample size is small (only six hives in each of three treatments), and the experimental design is suspect (the data are pooled to increase the apparent sample size of the neonic treated hives and analyzed by simple one-way ANOVA, when the design is certainly a repeated measures experiment and likely needs to incorporate a blocked design as well). During the treatment season bees were fed sucrose and HFCS laced with neonics but then were allowed to forage normally, without monitoring total insecticide exposure (including inadvertent environmental exposures, which might have significantly increased their total exposure). And so on.
It misses the multi-layered research that has been done the past few years. It appears that many factors are in play, so to go to a one-dimensional factor, at this point in time, seems odd.

(57,936 posts)many, many busy bees humming in the wood sorrel beneath my avocado trees. Used it once on one plant. Next day, about 10 a.m. not even half the bees I had the previous days. I am in S. Cal. and i think that my bees may live in holes in the ground as well as in the usual hives. You will know more about that than I do. But I don't use neonicotinides based on that experience. Just anecdotal, but i think there may be something to the claim. Can't prove it. But the claim can't be dismissed. The problem is what the trade-off is of giving up the use of neonicotinides, Is the probability that the neonicotinides is ruining hives great enough.
I drew my own conclusion. But I could be wrong.
If not neonicotinides, what do you think could be hurting bees?

(36,281 posts)Honey bees-- Apis melifera-- are only one species of bee out of hundreds of species that occur in North America. They're non-native, but were introduced to North America during colonial times for honey production, not pollination. They were not needed for pollination because native bees did a fine job of it by themselves. Honey was important as a luxury sweetener, however, because most of the sugar grown in the new world was used to make rum-- it was in high demand and therefore much too expensive for household use.
Honey bees became more important for pollination, especially large scale managed pollination, when modern farming practices began to create environments that are relatively hostile to native bees, such as large monodominant planting, removal of alternate foraging habitat (weeds, borders, hedgerows, etc), and the use of chemical pesticides during the non-flowering portions of crop life cycles. These practices create native bee deserts. Honey bees have so far managed to overcome those conditions, at least to some degree, by living in dense colonies that can be moved from location to location so they can pollinate crops when flowers are available, then move somewhere else with alternate forage-- often other crops-- before the pesticide deluge begins post-pollination. Honey bees therefore facilitate modern, big ag farming practices to a degree that native bees never could.
As for what's hurting "the bees," the same modern farming practices that concentrate pollination services on honey bees are largely whats affecting the many native bee species. For introduced honey bees, the best scientific consensus to date is that they suffer from a combination of factors-- possibly including exposure to low dose neonic insecticides, BTW-- but including stress from population management for agricultural use (transporting hives, overwintering on HFCS diets, exposure to a cocktail of hive management chemicals such as miticides and antibiotics, etc), genetic problems stemming from over-breeding, parasites (including several that are becoming more virulent rather than less), diseases including bacterial, fungal, and viral pathogens, and definitely exposure to some other pesticides like organophosphates in wide use for both agriculture and lawn care.
Here's a pointer to the most recent EPA/USDA report on honey bee population health in North America: http://www.usda.gov/documents/ReportHoneyBeeHealth.pdf

psiman
(64 posts)You have hit the main points more clearly and succinctly that I ever could have managed.
I will just add that the fundamental hypothesis of the entire project, as explained in the 2012 paper, is that CCD did not appear until many years after the introduction of neonicotinoids because the vector for exposure is trace neonic in the HFCS fed to bees in commercial hives - a change in beekeeping practice that was introduced around 2006; color me skeptical. I am prepared to grant that there may be some connection between long term sublethal exposure and difficulty in surviving the cold of New England winters, but that is a long way from establishing a connection between neoticotinoids and global CCD.

(36,281 posts)...and really none of the staple crops, like cereals, which are wind pollinated. Nearly all of the insect pollinated crops were once pollinated quite well by the host of native bee species that have largely been supplanted by agricultural practices-- modern, big ag-- that are better suited for honeybee pollination services. But seriously, loss of honey bees need not be associated with long term disruptions to food supply IF farming is adapted for native pollinators. The greatest impact will be upon the bee keeping industry itself, which will lose industrial scale managed pollination like the California almond pollination and honey production (native bees don't produce such a huge surplus).
And varroa mites are one of the primary threats to honeybee health, so I wouldn't diminish their importance, either.

And from Wikipedia:
On July 12, 2013, Rep. Earl Blumenauer, Democrat of Oregon, introduced The Save American Pollinators Act in Congress. If it becomes law, the Act will suspend the use of four neonicotinoids, including the three recently suspended by the European Union, until their EPA registration review is complete. The legislation will also require a joint Interior Department and EPA study of bee populations and the possible reasons for their decline.[22]

(36,281 posts)Most of the staple crops are wind pollinated or are efficiently pollinated by native bees when farming practices are not hostile towards them. Honey bees facilitate modern big ag, monodominant cropping in pollinator desert habitats. The notion that loss of their pollination services would cause "the whole world (to) starve to death" is ridiculous. Seriously.

Brainstormy
(2,380 posts)Roundup is definitely a pesticide also Classified by the FDA as a general use pesticide. Patricia Muir, of Oregon States Department of Botany and Plant Pathology, and an expert on the subject says:
The term pesticide is a general one referring to a chemical, physical, or biological agent used to kill insects, rodents or fungi. Sometimes called "biocides," the term encompasses fungicides, insecticides, and agents effective against other disease organisms, such as bacteria. Most uses include herbicides (agents that kill plants) as a kind of pesticide.

(5,562 posts)And I believe most in our neighborhood do too. There are lots of native flowering plants around, and I let garden plants to go seed specifically for the bees. Sometimes I'd see 10 different types of pollinators buzzing around one plant. The thing is, for the past couple of years I'm not seeing as many as I did before.
I think it has to do with several things. Pesticides and stress, yes but as I said there isn't any in use around here. Another biggie which I believe is overlooked is the proliferation of wireless, which screws up the bees navigation systems. These things were never properly tested for harm to people or other living creatures. I won't be able to believe there is no effect until I see the "science" proving that its harmless. All we have to go on now is the word of the corporations and governments and they want us to ignore the issue so we buy more.
Who is willing to give up the convenience of their cell phones, wireless computer and now smart meters emitting constantly on nearly every house? What if it turns out that they are killing off the pollinators and the bats who are also in a steep decline. We refused a smart meter, keep the cell phones off and unplug the wireless when not in use, but we're only one family. Everybody else is loaded to the gills with wireless. Everywhere.

And CCD has been found in many rural regions without cell phone signals, making me believe that pesticides are the more likely cause.

Our colony locations are permanent (we do not transport our bees to other locations),

(19,233 posts)Honeybees are not native to most of the world; they were exported from Europe as Europeans settled around the planet over the past millennia.
The only reason we need honeybees at all is because we practice highly destructive land practices that encourage farmers to grow monocropped thousand-acre fields, plow them fencerow to fencerow, clearcut every forest they find, plow under grasslands, and spray every nook and cranny of their property with more and more chemicals. We've given the many native bee species in North America, who are perfectly capable of pollinating crops, no place to survive, no habitat left to call their own.
Banning a certain chemical to save the honeybees is at best a short-term fix that will not last. Even without the neonics in circulation, the loss of bee habitat will continue to harm them, requiring the remaining colonies to be more and more dependent on their human owners to feed them and move them more frequently to areas in flower. It's a house of cards that cannot hold. We've already seen this with the monarch butterfly, with their overwintering populations on the verge of all-out collapse as their summer and winter habitats are destroyed and poisoned.
The only way we will get ourselves out of this hole is to ultimately abandon the forms of factory-modeled megafarming we currently employ and return to a system where farms were smaller, run by families, and cropped a diverse array of food. Multiple fields of different crops, using crop rotation, livestock grazing and permaculture techniques to maintain soil fertility and wildlife diversity. Such a system is far more resilient to climate change and the eventual depletion of fossil fuels, and would provide ample habitat for native bees to flourish and pollinate.
It might sound crazy and naive to some, a longing for a "Little House on the Prairie" lifestyle, but ultimately it's either this, or we continue to rely on farms run more like chemically-powered food factories to make sure we get our daily ration of "food-like product" every night for dinner.
