Skip to comments.Glyphosate perturbs the gut microbiota of honey bees
Posted on 09/25/2018 7:42:00 AM PDT by ding_dong_daddy_from_dumas
Increased mortality of honey bee colonies has been attributed to several factors but is not fully understood. The herbicide glyphosate is expected to be innocuous to animals, including bees, because it targets an enzyme only found in plants and microorganisms. However, bees rely on a specialized gut microbiota that benefits growth and provides defense against pathogens. Most bee gut bacteria contain the enzyme targeted by glyphosate, but vary in whether they possess susceptible versions and, correspondingly, in tolerance to glyphosate. Exposing bees to glyphosate alters the bee gut community and increases susceptibility to infection by opportunistic pathogens. Understanding how glyphosate impacts bee gut symbionts and bee health will help elucidate a possible role of this chemical in colony decline.

DUH. And what do you think it does to our equally necessary microbiota???
Pick up some probiotics at wallyworld.
Honeybees are an invasive species. The enviros ought to be search for effective pesticides that will kill the European honeybees while leaving native pollinators alone.
color me unconvinced.
Bee shortage is a lie.
The issue of “hive collapse” has been around for centuries. European bees at times were bred to combat this problem as early as the 1700’s.
There are thousands of different kinds of bees. The issue is complicated. I am presently skeptical that Roundup is the cause, but as a scientist, I will examine the evidence as it is presented. This study is interesting, but far from convincing.
“Agenda science” is difficult to detect, but remains a problem to the outside reader.
I’m not sure where you live, but around my parts (Western PA) many of us lost lots of our hives last year.
I had to start from scratch this year and imported both Italian and Russian (collusion!) queen’s. So far I managed to split one hive so we are at a net positive.
One beekeeper I know had 33 hives last year and only 7 made it through the winter.
Bee shortage is not a lie here in the north east.
Could they please make a version of Roundup that is toxic to mosquitos?
The appearance of the CCD calamity lines up much better with Neo-nicotinoids.
nicotinoids were rolled out from the early 1990’s thru 2013.
Roundup introduced in the late 1970’s.
CCD appeared big time in 2006.
Those weedy plants aren't generally the plants with flowers that bees feed upon.
So, I wonder, if Roundup is the culprit, how it is being used and on what plants it is used for the burn down.
Monsanto is now owned by Bayer.
Bayer is facing massive lawsuits on 3 fronts....ill effects of contrast dye from medical imaging, essure birth control, and now Roundup.
It’s cha-ching time for the lawyers.
Glyphosate increases the strength of butterfly wings such that a butterfly in the Congo causes increased eddy currents that travel to Africa and create tropical disturbances of the coast of Sierra Leone.
Cat 5 hurricanes! We all gonna die!
Before the government can properly utilize our earning potential....
Until we know more, I will try to figure out what food products have the Roundup chemical in their production, and avoid such products (although it's hard to be sure).
Been beekeeping 14 years.
Typically, I was getting used to losing 25% of hives over the winter.
A year ago, I had 8 hives. After the winter, I was down to 1, experiencing the most losses I’ve ever had.
now, two loses, I can say were due to carnivorous wasps. The bulk of my loses were probably mite related.
But, perhaps it’s glowbull warming (insert Goebbels icon here).
I'm just an old carpenter, so will bow to the expertise of your future findings.
I would, however, close by saying that the folks who own one of the largest honeybee pollination outfits in this half of the country are family friends, and their business is buzzing along quite nicely.
I just lost a colony this summer. They seemed fine in August. Then last week I noticed a yellow jacket coming out of the hive. So I opened it up and - not a bee in sight. All cells cleaned out.
Was that the wasps? There were not even any dead bees around.
Anyway, on the Roundup question... The plants with Roundup are DEAD. Bees don’t care about dead plants.
