Okay the latest news apparently is that is largely a nasty parasitic fungus known as Nosema ceranae
which is enetering through multiple vectors both mites, and actually eating it while cleaning house etc. IMHO by decreasing the the cell size in the hive the resultant decrease in Bee size will reduce the infection by the mites, but that still leave the other vectors open. Also this does stop the other stresses migrant beekeeping, pesticides, GM crop toxicity. I would guess that the main way to put a stop to this is end Migrant beekeeping with farmers maintaining their own hives, this will not produce excess consumable honey because some of the pollination occurs with Almond tree and other plants which can make honey inedible or poisonous. http://en.wikipedia.org/wiki/Mad_honey#Toxic_honey
below are some qoutes on the CCD causes
"Beeswax absorbs chemicals from the air, and research at Penn State University last year identified 78 different chemicals in beehives, of which 46 were pesticides, including DDT, he said."http://ydr.inyork.com/ci_12932511
"While the science isn’t completely settled, it’s increasingly pointing to a single-celled parasite, Nosema ceranae, as the prime cause, Pitcher explained.
“What it basically does is it causes bees to get immune deficiency disorder. So it’s actually causing the bees to almost get a version of HIV.”"http://www.bclocalnews.com/vancouver_is ... 98132.html
"Though everything from aliens to “God calling the bees to heaven” has been blamed, research is starting to give a clearer image of what’s really causing it. It has been found that CCD bees have more disease, he said, though not one disease in particular. Varroa mites, one of bees’ worst parasitic enemies, may play a part in this.
When they bite a bee, they “spit” into it, vanEngelsdorp said. When they do this they spit a virus similar to AIDS into the bee, weakening its immune system and leaving it susceptible to sickness. It’s also possible, he said, that when the bees leave they are practising a form of “altruistic suicide” similar to termites. "http://www.peacecountrysun.com/ArticleD ... ?e=1640534
"Agricultural Research Service scientists have sequenced the genome of an invasive parasite called Nosema ceranae that can kill honey bees and is one of the many suspects in the mysterious ailment known as colony collapse disorder (CCD)."http://deltafarmpress.com/news/bee-para ... html?imw=Y
"The bees may have been infected by single-celled, spore-producing fungus called Nosema ceranae. Nosema ceranae is one of many possible causes of CCD that bee researchers are looking into."http://www.montana.edu/cpa/news/nwview.php?article=7181
"Nosema ceranae was first found in Asian honeybees and has now jumped to European honeybees and can be found worldwide," said Gress.
Nosema's spore has a tough resistant wall protecting it from conditions in the host and in the environment. Conditions in the bees' intestines trigger the explosive release of spores and their contents into the cells of the host bee. The Nocema nuclei divide repeatedly inside the infected bee, producing large amoebalike organisms with multiple nuclei. Some of the organisms mature into spores, completing the life cycle.
There is an antibiotic that kills the parasite in its active, reproducing state, but no method of killing its spores. The spores are extremely hardy and can survive freezing, dehydration and extreme heat. During the winter when bees are hibernating, their spore-laden feces pile up in the hive. Sick bees often have diarrhea and defecate in the hive, greatly increasing the chances that other bees will be exposed.
"Spring comes along and the bees start cleaning out their combs and they reinfect themselves," Gress saidhttp://www.greatfallstribune.com/apps/p ... 9905200366
"We are not sure what causes CCD in the U.S., but it is probably multi-factored," said Gress. "It's like a perfect storm of high levels of infection by the varroa mite (a parasite that feeds on bee blood and transmits bee viruses), poor nutrition due to pollinating crops with low nutritional value, and pesticide use, but Nosema ceranae is probably the main factor."http://www.greatfallstribune.com/apps/p ... 9905200366
back in 2007 though a major suspect was Israeli Acute Paralysis virus among the culprits http://www.sciencemag.org/cgi/content/a ... ULTFORMAT=http://www.odemagazine.com/doc/50/give-bees-a-chance
