A Purdue University study shows that honeybees collect the vast majority of their pollen from plants other than crops, even in areas dominated by corn and soybeans, and that pollen is consistently contaminated with a host of agricultural and urban pesticides throughout the growing season.
Christian Krupke, professor of entomology, and then-postdoctoral researcher Elizabeth Long collected pollen from Indiana honeybee hives at three sites over 16 weeks to learn which pollen sources honeybees use throughout the season and whether they are contaminated with pesticides.
The pollen samples represented up to 30 plant families and contained residues from pesticides spanning nine chemical classes, including neonicotinoids - common corn and soybean seed treatments that are toxic to bees. The highest concentrations of pesticides in bee pollen, however, were pyrethroids, which are typically used to control mosquitoes and other nuisance pests.
"Although crop pollen was only a minor part of what they collected, bees in our study were exposed to a far wider range of chemicals than we expected," said Krupke. "The sheer numbers of pesticides we found in pollen samples were astonishing. Agricultural chemicals are only part of the problem. Homeowners and urban landscapes are big contributors, even when hives are directly adjacent to crop fields."

"If you care about bees as a homeowner, only use insecticides when you really need to because bees will come into contact with them," she said.

That line has no place in this summary. Please remove it. I agree with it, but it doesn't belong and should be removed.

What if that line was replaced with the Joni Mitchell lyric from Big Yellow Taxi--
"Hey farmer farmer, put away the DDT now; give me spots on apples, but leave me the birds and the bees."
Would that be acceptable? Personally I like these tag lines, forces me to evaluate the post again and maybe "do my own thinking".

I agree, doesn't belong. It's almost a non sequitur.
Organic doesn't mean pesticide-free. They just used pesticides classified as "organic", and often more of them since they aren't as effective. Some of those are pretty carcinogenic too compared to the carefully synthesized "non-organic" ones.

Can we get some citations about carcinogenicity of pesticides allowed in organic farming? And even red meat is "probably carcinogenic" and already Paracelsus knew in the 1500s that "does makes the poison"; If something can cause cancer but only in massive concentrations nobody gets exposed to it's fairly irrelevant.

I wonder if you could convince people that organophosphates qualify? Ever since they withdrew amiton from sale, it's been impossible to find anything that really gets rid of all garden pests.

The point I was obliquely making was that people are so obsessed with the perfect appearance of produce, lawns, and landscapes that farmers (or Big Ag) and homeowners are over-applying pesticides and wiping out the bees as collateral damage, when the irony is that organic vegetables taste better and are better for you even with a few insect-caused holes.
That is germane to the discussion, is it not?
The value of a site like Soylent is in its discussion, not as much in its actual articles, which you can go to ArsTechnica, Phys.org, and the like to read. I add brief comments to excerpts to kickstart discussion because in my experience they do. Many's the time, as a counter-test, I submit interesting articles with no comment or quip only to see them draw 0 comments. We could all subscribe to RSS feeds instead to get that.
But FYI, if you post criticism as an AC it's written off as a concern troll. If you want the all-volunteer editors, devs, and submitters to listen to your feedback, pluck up your courage, sign-in, and post the same under a real username. If you're real person with real feedback, you should have no problem doing that.

Summaries should summarize the article, not your opinion or thoughts about them. The place for that is in the comments. After you submit the article, make the first post your thoughts on it or maybe add a "submitter's comment" section to the summary. Just don't mix that with the actual article. It's unprofessional.
I'm AC because I don't like dealing with managing multiple logins across tons of sites. Tracking and the risk of data leaks is annoying too, but those are of less concern. According to you, if I just created a throwaway account and made one post, that post would have more weight than this post. That's simply stupid. It shouldn't matter what your name is, the only thing that should matter is the content of the post. The poster's background doesn't change what they typed. It could change the interpretation, but you have to already know the poster for that and this is a public site not a private club.

I'm not a professional. I'm a random dude who gave of his time, freely, to submit an article to a community site for discussion. So if you're demanding "professional" something from a place you pay nothing for, and don't contribute anything to, not even the merest soupcon of identity or reputation, then you're behaving like a ninny.

Controlling the spread of mosquitoes can be a matter of life and death in many parts of the world. Malaria, dengue fever, zika fever, chikugunya, Japanese encephalitis, yellow fever, filariasis, West Nile fever, and many more dangerous diseases are carried by them.
The real problem seems to be that we are changing conditions to allow these diseases to affect more people and to spread to places not evolved to handle them. There are a lot of ways that occurs, from bringing the diseases out of the treetops by clear cutting forests, to blanket spraying that harms the populations of the predators of the disease carrying pests faster and more thoroughly than the pests themselves, to moving people into new habitats and by moving the pests themselves into new habitats, to name just a few.

Pesticides aren't applied carefully to individual plants. Whether applied in the form of a liquid, or a dust, pesticides are applied in bulk. The wind carries the stuff far and wide. When applied from a tractor, you can see a cloud of dust or vapor being blown downwind. When applied from a crop dusting plane, that cloud is generally larger, and higher, so it settles even further down wind.
Even if herbicides and pesticides were manually applied carefully to individual plants, you would get downwind contamination. That doesn't address the spread of chemicals in the water. Nor does it address the fact that any "over application" goes into the soil, then it is often taken up into subsequent crops along with the plant's nutrients.
All herbicides and pesticides are poisons. We should use a lot less of them, everywhere.
