So that's what all the buzz has been about. My beeber is stungged.
Bee happy. Eat your honey.

Similar to the current Global CoolingWarming Gore trend..
Correct me if I'm wrong. Please!

All joking aside, this is a very serious problem. Without honeybees to pollinate, many crops cannot thrive, and major colony losses will have very serious and immediate consequences to our food supply.
Much of the problem for beekeepers is the vast amount of honey being imported from China and Vietnam: China imported over 270 million pounds of honey to the U.S. last year. The total demand for honey is just over 400 million pounds, and beekeepers are forced into leasing their colonies to growers for pollination purposes.
It is suspected that the constant moving, by truck, of large quantities of bee colonies is the major cause of the decline in bee populations. One of my neighbors recently shipped nearly 5000 colonies to California to help pollinate the almond crop. He gets around $130 per colony for this service, and due to the decline in the demand for domestic honey, he needs this income desperately. His losses on the trip were almost 20% of the total shipped.
If you are a consumer of honey, be sure you buy American honey.
Yeah, I saw that. I gave me immediate, negative thoughts.
I know we have at least 2 beekeepers here at FR. I can't remember their usernames though.
Maybe they are on Travis' ping list.
I was a beekeeper years ago - I think the other freeper's user name was "beekeeper".
Have you heard of this mite?
My first problem back in 1980s was American foulbrood. Has a distinctive odor of dirty socks, so I burned the entire hive, bees and all, rather than contaminate the other colonies.
Later, African bees invaded one of my colonies and I figured I was getting too old - but I had a really good time for over 10 years.
It looks like it is an invasive species. This definition says it was introduced:

Reducing the size of the wax foundations' cells sounds more logical than chemically treating a colony, as the mites build up a resistance and the honey may not be fit for human consumption. Coating the bees with powdered sugar sounds good though probably not perfect.
With smaller cells the bees will be smaller, and the honey/pollen production will be less. Italians are nice and big, good housekeepers, too.
You're talking big money if purchasing new queens to introduce and force swarming. For every swarm, you'll need more woodenware, frames.
Egad! don't get me started talking about beekeeping ....
I find this interesting:
[no bee remains are typically found around colonies struck by the mystery ailment. Scientists assume these bees have flown away from the hive before dying]
One possible explaination is that the bees get lost and are unable to return to the hive.
Possibly due to:

Since birds have parasites, would this affect a birds mirgration?
And this university paper:
http://sifaka.cs.uiuc.edu/~qmei2/data/honeybee.biosis-1998.biomodel.xml
(html formatting is off; but the information is there)
says: "Imidacloprid is increasingly used worldwide as an insecticide."
So this is being sprayed? That means it isn't the mites?

The problem has been evident for a very long time.
I lost and replaced several colonies in the mid 90's. Careful attention and management was ineffective.

The html on that is broken. So it comes up a bit messy. It is a study paper that was done about hand pollinating plants and pathogens damaging insects.
It also goes over using imidacloprid as an insecticide.
It says, "The main targets of the insecticide imidacloprid are neuronal nicotinic acetylcholine receptors within the insect brain."
"Imidacloprid was a partial nicotinic agonist, since it elicited only 36% of ACh-induced currents and competitively blocked 64% of the peak ACh-induced currents. GABA-induced currents were partially blocked when imidacloprid was coapplied and this block was independent upon activation of nAChRs. Our results identify the honeybee nAChR as a target of imidacloprid and an imidacloprid-induced inhibition of the insect GABA receptor."
nAChR = nicotinic acetylcholine receptors
Nicotine enhances cognitive functions, such as learning, memory, and retention through activation of brain nicotinic acetylcholine receptors (nAChRs).
The most common nicotinic receptors found in the brain are the low affinity a 7-nAChR and the high affinity a 4b2-nAChR. a 7.
***Imidacloprid, which is being sprayed as an insecticide, it is an agnostic. An agnostic is used to affect the addictive properties and some of the side-effects of nicotine.***
