MM: A recent Washington State University (WSU) study measured honey bee colony exposure to four neonicotinoid insecticides (clothianidin, dinotefuran, imidacloprid, and thiamethoxam) in urban, rural and agricultural settings. What did the researchers find?

***

[JC:] In rural or urban landscapes, they found less than 5 percent of beehives in a two-year period had any detectable residues at all. The authors of the study concluded there is no risk of adverse effect on beehives in rural and urban landscapes, and there was a very low risk in agricultural landscapes. The highest amount found was 3.9 parts per billion in an agricultural landscape. EPA considers 25 parts per billion the cutoff for potential for adverse effects.

ARA comments on EPA’s imidacloprid registration review

From: AgProfessional

By Agricultural Retailers Association

***

ARA supports the use of risk-based assessments in understanding factors that may impact honey bee and native pollinator health. EPA needs to use widely accepted, peer-reviewed science and methodologies as it relates to any preliminary pollinator assessment for imidacloprid or other critical agricultural pesticide products.

The key to any short-term and long-term solution to improve pollinator health is through a diverse public-private partnership that brings together all impacted segments such as agribusinesses, farmers, commercial beekeepers, government agencies, conservation groups, manufacturers, and food processors. Read ARA’s comments to EPA

Rising CO2 levels threaten bees

From: Agri-News

WEST LAFAYETTE, Ind. — Rising levels of atmospheric carbon dioxide have reduced protein in goldenrod pollen, a key late-season food source for North American bees, a Purdue University study shows.

Researchers found that the overall protein concentration of goldenrod pollen fell about one-third from the onset of the Industrial Revolution to the beginning of the 21st century.

Honeybee Mite Infestations More Severe Than Once Thought

From: Lancaster Farming

Key findings show that the varroa mite, a major honeybee pest, is far more abundant than previous estimates indicated and is closely linked to several damaging viruses.

Also, the results show that the previously rare Chronic Bee Paralysis Virus has skyrocketed in prevalence since it was first detected by the survey in 2010.

How pathogens such as viruses affect new honey bees health?

From: National Daily Press

***

Research in the Flenniken lab is aimed at better understanding how multiple biotic factors such as viruses, bacteria, fungi and mites affect colony losses with other factors such as agrochemicals and weather events.

“It isn’t just one factor” that’s responsible for colony losses,” Flenniken said. “Currently, researchers are focused on determining how multiple, synergistic factors cause the death of a colony.”

Varroa Mites and Associated Honey Bee Diseases More Severe than Previously Thought

From: Entomology Today

Researchers from the University of Maryland and the U.S. Department of Agriculture recently completed the first comprehensive, multi-year study of honey bee parasites and disease as part of the National Honey Bee Disease Survey. Key findings, which are published in the journal Apidologie, show that the Varroa mite, a major honey bee pest, is far more abundant than previous estimates indicated and is closely linked to several damaging viruses. Also, the results show that the previously rare chronic bee paralysis virus has skyrocketed in prevalence since it was first detected by the survey in 2010.

The first multi-year honeybee disease study in the United States has revealed that varroa mite infestations in the country are far worse than what was previously believed, as the population of the deadly pests is more abundant than ever.

Contrary to EPA, new report finds neonicotinoids boost yields in soybean fields

From: Genetic Literacy Project

The GLP aggregated and excerpted this blog/article to reflect the diversity of news, opinion and analysis.

The class of insecticides called neonicotinoids (neonics) were introduced to a lot of fanfare from farmers and environmentalists alike. They were seen as far less toxic than alternative pesticides, and could be applied into the soil or on seeds, avoiding the damage to beneficial insects that’s often caused by sprays.

***

Gore and his colleagues discovered that treating soybean seeds with neonics (imidacloprid or thiamethoxam) and a fungicide provided higher yields than seed treatments using a fungicide only. . . .

This Dog’s Certified Nose is Saving Bee Colonies from Disease

From: GoodNewsNetwork

by Terry Turner

Klinker may look like any other black Labrador retriever, but she’s the only dog in America that can do this job — sniffing out disease and saving whole colonies of bees with one visit.

Since 2008, Klinker has been sniffing out American foulbrood — a bacteria that if not caught right away, can sweep through a colony, jumping from hive to hive and destroying any larvae. It’s the most common and destructive disease facing honey bees, but it’s no match for this dog’s nose.
