UV radiation

Any known research about UV radiation effects on bees, and a possibility that the thinning ozone layer might play a role? I know this is not the place for OR, but if there is research about this the article should probably also be updated... 66.11.179.30 (talk) 06:56, 1 November 2011 (UTC)[reply]

If I remember correctly, bees can see soft ultra-violet and distinguish its polarization. They use the polarization of the Sun's UV to help them navigate. JRSpriggs (talk) 14:57, 1 November 2011 (UTC)[reply]

Parasitic fly

Recent yahoo article referencing Scientific American suggests that CCD is caused by a parasitic fly. Suggest this is worth incorporating. http://news.yahoo.com/zombie-fly-parasite-killing-honeybees-230200867.html — Preceding unsigned comment added by 69.171.163.211 (talk) 01:04, 11 January 2012 (UTC)[reply]

Citation NOT needed: Selective commercial breeding and lost genetic diversity in industrial apiculture

The statements made here are based on two articles from respected sources: The Economist magazine, and the British Academe.

The other articles linked themselves have citations which could be brought over to discuss Hybrid Vigor. The danger of monoculture in agriculture is well understood. Nothing said there is incorrect, and the entire statement is in line with current perspectives on Science, as do the two links at the end of the paragraph. — Preceding unsigned comment added by 66.108.135.242 (talk) 14:38, 12 January 2012 (UTC)[reply]

Depolarization?

Has anyone considered the possibility that particulate pollution may be depolarizing the Sun's light leading to a failure of the bees' navigational abilities? JRSpriggs (talk) 05:19, 17 March 2012 (UTC)[reply]

Discussion of two 2012 studies related to the pesticide section

I have had a discussion on my talk page about two studies recently added to the article. If it's OK with the other editor, perhaps we can move our conversation here? Gandydancer (talk) 14:53, 17 March 2012 (UTC)[reply]

Two new articles in Science implicate neonicotinoids in colony collapse disorder

From Science magazine tomorrow:

"Five years ago, bees made headlines when a mysterious condition called colony collapse disorder decimated honey bee colonies in parts of the United States. Now bees are poised to be in the news again, this time because of evidence that systemic insecticides, a common way to protect crops, indirectly harm these important pollinators. Two field studies reported online this week in Science document problems. In bumble bees, exposure to one such chemical [imidacloprid] leads to a dramatic loss of queens and could help explain the insects' decline. In honey bees, another insecticide [clothianidin thiamethoxam] interferes with the foragers' ability to find their way back to the hive. Researchers say these findings are cause for concern and will increase pressure to improve pesticide testing and regulation."

More popular treatment summarization is available from the BBC who have seen the articles which are embargoed until tomorrow. 70.58.11.42 (talk) 21:32, 29 March 2012 (UTC)[reply]

A more detailed study (same methodology but more doses and a different interpretation) has already been released on PLoS ONE [1]. That study, unfortunately, got little recognition. While effects were noted, they were at dosages between 5 and 50 times higher than the dosages seen in the field. Rossami (talk) 21:51, 29 March 2012 (UTC)[reply]
There is another PLoS ONE article which used mass spectrometry to suggest multiple exposure routes not previously considered. I believe that has an impact on the actual dosages involved, and in any case both RFID studies involve sublethal doses causing honey bees to fail to return. 70.58.11.42 (talk) 23:37, 29 March 2012 (UTC)[reply]

"Use of Common Pesticide, Imidacloprid, Linked to Bee Colony Collapse" in a Harvard School of Public Health study. 71.215.74.243 (talk) 18:27, 6 April 2012 (UTC)[reply]

The HBR study has already been discredited for serious failures in methodology. See, for example, here. Rossami (talk) 18:38, 6 April 2012 (UTC)[reply]
Err....discedited on a message board by "Randy Oliver"?... Gandydancer (talk) 21:54, 6 April 2012 (UTC)[reply]
That would be Randy Oliver, publisher of [scientificbeekeeping.com/ Scientific Beekeeping], frequent author in [www.americanbeejournal.com/bAmerican Bee Journal] and widely respected researcher and commercial beekeeper. Yes, his credentials are good. BEE-L, by the way, is the premier discussion board for "informed discussion of beekeeping issues and bee biology". It is not just some message board. Rossami (talk) 23:25, 6 April 2012 (UTC)[reply]
Not sure what HBR is, but the original HSPH press release is at [2] and the paper which Oliver quotes from is at [3]. It seems that Oliver's concerns about dosages are addressed on the lower first column of page 2. 71.215.74.243 (talk) 22:42, 6 April 2012 (UTC)[reply]
Wired goes in to detail on the dosage controversy regarding the Harvard study. 71.215.74.243 (talk) 23:24, 7 April 2012 (UTC)[reply]
