Popular Pesticides Keep Bumblebees From Laying Eggs (npr.org)
An anonymous reader quotes a report from NPR: Wild bees, such as bumblebees, don't get as much love as honeybees, but they should. They play just as crucial a role in pollinating many fruits, vegetables and wildflowers, and compared to managed colonies of honeybees, they're in much greater jeopardy. A group of scientists in the United Kingdom decided to look at how bumblebee queens are affected by some widely used and highly controversial pesticides known as neonicotinoids. What they found isn't pretty. Neonics, as they're often called, are applied as a coating on the seeds of some of the most widely grown crops in the country, including corn, soybeans and canola. These pesticides are "systemic" -- they move throughout the growing plants. Traces of them end up in pollen, which bees consume. Neonicotinoid residues also have been found in the pollen of wildflowers growing near fields and in nearby streams. The scientists, based at Royal Holloway University of London, set up a laboratory experiment with bumblebee queens. They fed those queens a syrup containing traces of a neonicotinoid pesticide called thiamethoxam, and the amount of the pesticide, they say, was similar to what bees living near fields of neonic-treated canola might be exposed to. Bumblebee queens exposed to the pesticide were 26 percent less likely to lay eggs, compared to queens that weren't exposed to the pesticide. The team published their findings in the journal Nature Ecology and Evolution.
No bees means no pollination. Farmers recognizing this will voluntarily reduce their use of these pesticides once they consider what manual pollination would entail.
Watch them say that bee population decline is a hoax, a conspiracy from the Evil Scientist Conglomerate to suck up more grant money. Or watch them say that bee populations are declining, but that human activity has nothing to do with it, that the science isn't settled, that bee populations have been "naturally" varying for centuries.
Etc etc etc.
Sometimes I think if cancer cells could talk, they would hold a similar discourse to all these fucking denialists, refusing to admit that THEY are responsible for the slow decline of their host.
You're a fucking moron.
Funny, never seen a bee egg on the menu. Sounds like FAKE NEWS!
Bees consume pollen. Some even call it 'bee bread'...

so deal with it.
from TFS: "They play just as crucial a role in pollinating ... [as honeybees]"
This seems to be an exaggeration. Mild for Slashdot, but extreme for scientists. My own anecdotal experience is that for every bumblebee I see, there are 1,000 honeybees. How can their work be comparable? And yes, I've seen a lot of bees during my time as agriculture inspector with the department of Food and Agriculture. This is a science story and the entire study is in doubt when such distorted language is used. This is the language of marketing people, not scientists. It's the kind of language you might expect from an outfit that has to capitalize every word in a headline, just as the hucksters did hawking newspapers in 1920. I hope it reflects another Slashdot edit failure and not the words of actual scientists.
...omphaloskepsis often...
there are other pollinators out there.
We could switch to robotic pollinators.
The robots pollinate, but they don't produce honey.
I'll bet you didn't know that Rhonda Brooks, the editor of aggprofessional.com, worked in marketing communications for DuPont for a few decades. DuPont manufactures one of the pesticides that's blamed for killing bees.
I see you also linked to a USDA report from August 1. Donald Trump appointed Sam Clovis, who has no science background at all to be the head scientist at the USDA. His work experience was as a campaign staffer for Rick Perry (noted idiot who now heads the Department of Energy). This after the Administration announced that all scientific publications from government agencies could not be released until they were vetted by the White House.
Then, the one actual scientific article you link to actually refutes your points.(read the article, it's short)
You believe what you want to believe, bucko. You're entitled to your own reality and don't let anybody tell you different.
You are welcome on my lawn.
The Green Revolution only shifted the catastrophe from mankind to plants & animals. It's enabled us to unwittingly explode in population - for what? Does a person who was never born suffer for never having existed?
The Pesticide is Neonicotin in Monsanto's RoundUp.
Monsanto is to blame.
Any relation to Colony Collapse Disorder?
With Bumblebee gone, we might be spared another Transformers movie...
We used to have a Bill of Rights. Now, with the rights gone, all we have left is the bill.
RoundUp is glycophosphate, not a neonic.
Glycophosphate is a major reason you're as likely to kill your plants as to fertilize them if you dump "free" manure on them... the cows & horses eat grain with RoundUp in it, and their shit ends up being poisonous to plants for a few months until the glycophosphate breaks down.
Also pollinator robots are not sustainable, they do require maintenance, bees are part of other invisible relationships with other unknown aspects of the world ecosystem, basically we don't know enough what other problems might bring their demise.
These nasty mofos STING!!! Kill them all with fire! (or with neonicotinoids, if that's cheaper).
Bumblebees are the most peaceful kind of Apidae. And also one of the most important polllinators because they fly out when other insects are still hibernating due cold temperatures.

We need to consider this story in abstract - and when we do it is much more disturbing.
In essence, what has happened here is that a pesticide supplier, i.e. a commercial organisation that is required by law to have their products tested and approved by a Federal agency, developed and tested a product which has now been shown to be detrimental to the environment in a pretty significant way.
But what would have happened if the detrimental impact from this chemical had caused sterility in men, for instance? Or early onset dementia? Or some other unpleasant, irreversible side effect? The whole point behind having Federal agencies and licensing requirements is to ensure that no chemicals released into the environment have such results.
It's easy to think that, in the 21st century, these are exaggerated or "doomsday" scenarios. If we thought that, we'd be wrong. Mankind does not learn from past mistakes in this regard. In the mid 1940s, the US released huge volumes of DDT into the environment. The chemical caused the shells of (wild) bird eggs to be super-thin and especially brittle and was responsible for the near-extinction of the Bald Eagle. In the 1950s, the drug thalidomide became widely available - resulting in literally thousands of individuals being born with mal-formed limbs, unable to care for themselves. The list goes on...
Bottom line: the moment we put profit ahead of public safety, scandals follow. As a sophisticated society, with a well-developed and functioning scientific community, there should be no excuses for the situation we see described in this article. The doubly sad and shocking thing is that it seems it will only be when we experience a potentially extinction-level event that we will see a determination to do something about this. By then it might be too late.
Corn is wind pollinated. Bees have nothing to do with it. Hence the tassels.
Bees do consume pollen, but I think you were talking about the worker bees.
The worker bees consume nectar and store the excess to feed the rest of the bees. In the meantime, they bring their pollen basket around which pollinates other flowers.
Great! Let's replace all the bees with the next best pollinator, mosquitoes!
Nicotine has been shown to have a similar effect on mammals.

I know its not the same, but they are part of the same family of chemicals, this should really have been investigated before they were approved for wider use.

How....how do we know? Who speaks "Bee" ?
Introducing "altruistic pollinators" would put evolutionary pressure on flowering plants to stop producing nectar (which is waste of plant's resources if it is not needed), and that would screw remaining pollinators even further.
RoundUp is a herbicide. Neonics are pesticides, and are not among the active ingredients in RoundUp.
I know in my yard, the ONLY thing I use neonicotinoids on are my non-flowering ornamental bushes (which are trimmed enough to keep from flowering). Without it, unfortunately most would all be dead due to scale. Yes, I tried everything else and nothing worked until I applied Merit and that stuff is magic. Applied only once a year and the problem is gone.
Maybe the fact that they cannot survive without putting toxic chemicals on them is a hint you should take. How about planting something that doesn't require special toxins to survive. Native plants are usually a good start.
I don't think the casual use by homeowners seeking protection of some established ornamentals is much (if any) exposure to bees.
Based on what evidence? You "don't think" it is a problem why exactly? And we're not talking about one or two homeowners. We're talking about millions of them all across the country using quite a lot of the stuff. Furthermore the chemicals don't just stay were you spray them and they don't magically disappear.
I would not be in favor of any type of across-the-board ban of neonicotinoids if it would mean taking it out of the hands of responsible use in ways that can't possibly be much danger.
Given that there appears to be substantial evidence of important negative effects on critical pollinators, exactly what is the basis of your argument? Because you think your are being "responsible" with them? Particularly in regards to plants that are purely ornamental. There is such a thing a responsible use in the food supply but no such thing exists for ornamental plants including lawn grass. If your lawn requires even occasional spraying then you are Doing It Wrong.
ad hominem much?
You can't arbitrarily dismiss articles based upon who wrote them. You have to do so based upon the content. From your response, you didn't give any indication that you made your decision based upon the content but rather the author.
As you said, "you believe what you want to believe, bucko".
When we open their hives and see that they actively store and eat pollen. Because we can see it with our eyes. Our eyes speak bee.
1) Whooosh
2) There are small signs in the bee-hives saying "bee bread"?
When we open their hives and see that they actively store and eat pollen. Because we can see it with our eyes. Our eyes speak bee.
Sure. But how do you know what the bees call it?
Are you telling me that cell phones are NOT the cause??? color me shocked
Quoting the number of managed beehives, which number people work hard to maintain because they need that many hives for their business, says nothing about the survival of individual bees or individual hives.
ad hominem much?

Actually, yes you can in science. You need credential in order to be credited on your work. If you have already had a long record of strong opposition to certain issues, your credibility on any work on the issues needed to be heavily verified again due to bias. Thus, ad hominem in this case is OK.
For the record, as an aside to this, let's set the record straight on DDT:

Other publications follow up on that.
We need less belief and more facts!

And I hate you, so lets just kill you. There are other human beings out there.
Fucking moron. You're not even funny.
Beesexuals? Hard to get laid without talking first...
get it
Bumblebees are the most peaceful kind of Apidae. And also one of the most important polllinators because they fly out when other insects are still hibernating due cold temperatures.
They are indeed passive, but they aren't above using their greater size to bulldoze smaller insects out of the way when they decide they want to visit a particular bloom. It can be entertaining sometimes to watch them work.
What I meant, of course, is that they generally only attack people if hurt. And even then they might just as well bite instead of stinging. I really have a lot of fondness for bumblebees.
"It's such a fine line between stupid and clever" -- David St. Hubbins, Spinal Tap
They establish a hive near your home, and you accidentally (or intentionally disturb it.)
We had them nest in one of our compost piles one year, would get aggressive any time people came near it, watered it, etc.
Just in the past six months we've seen them burrowing into a wooden fencepost.
Having said all that: There is far more diversity in 'bee' and other pollinating insect populations this year, but between drought, earlier than usual heatwaves, early/late blooming, and a variety of other factors, there are almost no pollinators at this point in the season, even though the diminished but diverse population earlier in the season seems acceptable.
This is CA btw.
I have a special appreciation for bumblebees as well, as they were my introduction to entomology at an early age. Never once was I stung, even when I deserved it!
