Yes:
The Agency also warned that spraying before dawn could leave traces of potentially harmful products on plants and in dew. Speaking to French newspaper Le Figaro on Wednesday, Axel Decourtye, scientific director at bee institute Itsap, supported the Agency's conclusions, saying "with the exception of wild bees that nest in the ground, darkness is effectively the only guarantee that there are no foraging bees in crops. The persistence of plant products means it is necessary to restrict their application towards the end of the night or at dawn."

Yes, absorbed. And at night, bees are not around anymore.

I know, but at least I think is is a good step, I hope the little friends can detect the products have been sprayed on the plants and avoid them. Probably still less pollination, but not less bees.
Today, they are being sprayed themselves, which is lethal.

We could put up signs, warning the bees.
You'll never get very far if all you do is follow instructions.

Depending on the poison, possibly yes. In addition to being absorbed through the pores (stomata) in the leaves, all insecticides commonly used have a half-life; once several half-life periods have passed, they are nearly undetectable. Applied properly, this can allow treatment to be effective during the night, with no measurable trace of the toxin remaining on the leaf surface in the morning. Are they likely to select an appropriate pesticide with a short enough half-life, then apply it in the correct concentration? Probably not, but that's a separate question. 
As a side note, whenever I hire a bug sprayer for the house, I ask him "What's the half-life of that stuff you're spraying?" If he doesn't know the answer, he doesn't come back. Ever.

I'm guessing you never get your house sprayed.

I haven't in a long time. I do it myself, like most everything else. My Dad was an agronomist, an expert in soils, plant feeding and culture, and pest identification and control. He taught me a lot more than I now remember, but these new kids aren't being taught anything at all!

I suspect wide-scale famine, disease and war will solve the problems of climate change, bee collapse, etc. fairly soon by reducing the world's population to a more sustainable level. Not trying to start to start an opinion war here, but it really does seem like we've created high-level problems faster than we can solve them, and having never addressed foundational problems, they will rear their ugly heads as a natural response to those higher level problems.

People who want to reduce the world's population should start with themselves. Any volunteers?

Sure, and people who want to solve world hunger should just eat. Much as people like to believe that contributing on a small scale changes anything, it really doesn't. Meaningful change starts with organization, rallying, politics, not with insignificant ants. Convincing ten other people is ten times as effective as just doing it yourself, whatever "it" is.
Also, that's not what Marc wrote, he wrote that it will happen (automatically), not that he wants it to happen or that he wants it to be done (actively).

Poor little bvggers have the odds against them
1) the varroa mite (not yet here in the south of the planet)
2) climate change
3) pesticides
considering that bees are a necessity to produce food for us humans, you'd think we had better plans by now - then again, we think we're the smartest thing on the planet, and that's plainly not true

Considering that the bees are responsible for a significant portion of the pollination of many plants, a bee die-off would precede a large plant die-off as well.

yeah - that's sorta what I meant by "bees are a necessity to produce food for us humans", but, looking at your comment, it goes further than us humans

Shambles?[^]
2 years to go and only 10% complete.
I see trouble ahead.
Every four years the worlds greatest athletes descend upon one country to compete for the ultimate prize.
Then, two years later there is an Olympic Games.

This happens at nearly every event. I remember the stories that England might step in to host the 2010 WC as South Africa were way behind schedule (England already having enough stadiums with the required capacity). I think there were more about the Brazil WC this year.
The 2016 Olympics will definitely take place in Rio.
