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.
Bees don't consume pollen. Bees carry pollen from flower to flower as they move from one to another to consume nectar. Damn! Do they not teach this stuff in school anymore?
i hate bees. mean fckers. let them all die. there are other pollinators out there.

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...
While idiots like you continue to cherry pick data to spread fear, actual scientists that understand the importance of a longer sampling rate are reporting something very different (2.62 million colonies in 2017, a slight increase from the graph, and the number of managed hives has increase 45% in the last half century. Where is your 33% drop fool???)
The real reason why you are an idiot though is because you choose to believe numbers that only include commercial hives - which being a monoculture are of course prone to large drops at times, but as we can see also quickly recover because it turns out bee keepers can breed more bees *surprise gasp*.
Keep your moronic fear mongering to yourself. You are seriously worse than the anti-vaxxers in terms of your inherent and very un-scientiffic fear of pesticides which massively increase crop production and help feed the world.
Talk about denial...

Kill'em all. They are just a pest.
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.
These nasty mofos STING!!! Kill them all with fire! (or with neonicotinoids, if that's cheaper).
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.
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" ?
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.
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"?

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
For the record, as an aside to this, let's set the record straight on DDT:

We need less belief and more facts!

Beesexuals? Hard to get laid without talking first...
get it
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.
