Bee pollinators contribute more than $200 billion in revenue from vegetable, fruit and nut production in the U.S. To gain a better understanding of current honey bee health in Colorado, the Colorado Department of Agriculture has taken part in the National Honey Bee Health Survey for the last three years.Laura Pottorff, CDA Division of Plant Industry’s Apiary Program Manager, explains

Pottorff: “The more that we do this, the better our data becomes. It gives us a better window into what is going on with managed bees. We are seeing a number Varroa mite —which is a parasitic mite — that is high in both our commercial and hobby apiary. As well as a few other diseases, but it is the Varroa mite that we think is the most important. That is also true nationally as well. So this parasitic mite feeds on the blood or the hemolyph of the bees and it also transmits or spreads virus diseases to the bees too.”

Grooming Gene Protects Bees from Deadly Varroa Mites, New Study Finds

From: Guelph Now

Constant Scratching Gene Protects Bees From Lethal Mites

Grooming Gene Protects Bees from Deadly varroa mite Mites Through Constant Scratching

A gene linked to grooming could be the key to saving honeybees from the deadly varroa mite, according to new University of Guelph research.

Prof. Ernesto Guzman discovered that honeybees with higher expression of a gene linked to vigorous scratching are better at removing mites from their bodies, and more resistant to the bugs, than bees with lower gene expression.

The Biology of the Varroa Mite – June 12, 2017

From: Surry County Beekeepers Association | A chapter of the NC State Beekeepers Association

State Apiary Inspector Greg Fariss will be back to talk about the biology of the varroa mite (Varroa destructor). The varroa mite is currently the biggest threat to our honey bees and in order to effectively manage them in the bee yard, we need to understand about their biology and the life cycle of the female varroa in particular. Please join us for this excellent presentation.

On pesticides we must let science lead the way

From: Daniel Dalton, MEP for the West Midlands


Now, in a case study of how the EU really works, the EU is involved and is threatening to ban these pesticides. The story started several years ago in France, when the government there, keen to keep the green support to prop up the government, agreed to the green demand to ban three neonicotinoids, citing several arguments (not backed up by scientific evidence) that they affect bee populations.

Colorado Department of Agriculture shares the latest survey data on the health of managed honey bees

From: Colorado Department of Agriculture via The Fence Post

BROOMFIELD, Colo. — Bee pollinators play a crucial role in natural and agricultural ecosystems and contribute over $200 billion in revenue from vegetable, fruit and nut production in the United States. To gain a better understanding of current honey bee health in Colorado, the Colorado Department of Agriculture has taken part in the National Honey Bee Health Survey for the last three years.

Varroa Causes Losses of New Hampshire Bees

From: Valley News

Concord Monitor


The exact reason why the hives were lost is unknown. Of the 239 responses received on why hives died, almost 45 percent of beekeepers reported they didn’t know what caused their hives to die. The next-highest cause was varroa mites, at almost 30 percent, and starvation at around 17 percent. “Other” reasons included weakness and mice. The survey notes many of the responses listed multiple reasons for hive loss.

Detection of varroa: 5 new outbreaks confirmed in the island

On Thursday, may 4, the bee surveillance network detected the first case of presence of the varroa parasitic mite in honeybees, in an Apiary located Saint‑Denis. A shipment in metropolis for confirmation has been done as of Friday, may 5. The national reference laboratory (ANSES Sofia Antipolis) confirmed the identification of the varroa Tuesday, May 9.

VARROA, VARROA, VARROA! Not Neonicotinoids

From: American Bee Journal

The Classroom – May 2017

Jerry Hayes – (excerpt)



I wrote you earlier in the year and asked you your opinion about why my bees died. I was positive that it was some kind of pesticide exposure from farmers around me late last year that showed up under winter conditions. You asked me about sampling and treating for mites and what did I use and did I sample after to see what the count was to see if the treatment worked. The state bee inspector came out and took samples and sent them off to the USDA Lab to be analyzed. The report just came back and I had 33.9 mites per hundred bees. As much as I hate to admit it, you were right. Just wanted to let you know.

Regulation Fail: The EU’s Neonicotinoid Ban is an Ecological Disaster

From: Forbes

Pesticide Regulation In The European Union: The Worst Has Become The Norm

  • The kicker was that the ban produced no benefit–zero, none, zip–to bees or other beneficial insects–which was, after all, the whole point of the wrong-headed exercise.
  • in 2016 oilseed rape acreage in the UK fell for the fourth straight year and UK farmers lost £18.4 million and almost 28,800 hectares of crops due to the ban.
