Read through it carefully, the typical media bias is huge. Cut to the chase, this is speculation, not proven fact. It also ignores effects of environmental toxins and pesticides. But the likelihood is very high that other researchers will soon reach similar conclusions.

I'd like to find the actual research. Thanks for posting.

DWV has spilled over from Honeybees into the common eastern bumblebee. Meaning, DWV can replicate in the common eastern bumblebee. So, besides Varoa destructor and Honeybees, you can now add the common eastern bumblebee to the DWV host list.

This isn't speculation, biased, or emotional.

By the way, if you sample bumblebees in the eastern U.S., the majority of them will be the common eastern bumblebee.

When you consider how many colonies are lost via Varroa mediated DWV infections, you can understand why DWV infected bumblebees are a new kind of a threat to Honeybees because they share so many pollen/nectar sources.

Seems to me that early on the feral bee population, read all honey type bees, were almost totally wiped by the mites. This is now NEWS? Under what rock have our news media been hiding? :ws: and have been for what, a decade or more?

The language is certainly sensational: "the study shows is that "the spillover for bees is turning into (a) boilover," University of Illinois entomology professor May Berenbaum, who wasn't part of the study, said in an email."

This followed by: " co-author Matthias Furst of the University of London said the team's research does not definitely prove the diseases go from honeybees to bumblebees."

The words "studies show" appears several times in this article. I have learned to be skeptical when someone refers to unspecified "studies".

Is this a new development, or is this a dynamic between bumbles and honeys that has been around for centuries, and is now being discovered?

Here's a link to the Li paper showing DWV replication in Bombus huntii (Hunt's bumblebee):

http://www.bioone.org/doi/abs/10.1603/EC10355

What I'm finding to be a bit 'off-putting' about the new Furst study is that they have failed to cite two key papers (Levitt, 2013) and (Li, 2011).

That's disingenuous because anyone who has been following the field of pathogen spillover between Honeybees and bumblebees knows that both the Li and Levitt papers where 'groundbreaking' .

They were the first to demonstrate DWV replication in American Bumblebees, the common eastern bumblebee and Hunt's bumblebee.

Here's a link to (Plischuk, 2009):

http://www.bioapi.it/images/pdf/nosema_en_bombus.pdf

"When considered in conjunction these molecular and quantitative data and the lesions macroscopically detected in ventriculus suggest that N. ceranae can parasitize individuals of all bumblebee castes in this country."

I don't see (Plischuk, 2009) cited either by Furst, et al. .

Tut, tut, tut.

Here's the press release they put out:

http://www.eurekalert.org/pub_releases/2014-02/babs-mhl021914.php

I guess that it is 'news' to them in the U.K. .
