Weak Honey Bee Colonies May Fail From Cold Exposure During Shipping

by Kim Kaplan  FARGO, NORTH DAKOTA, April 18, 2019—Cold temperatures inside honey bee colonies may cause colony losses during and after long-distance hauling, according to a preliminary study by Agricultural Research Service (ARS) scientists.Every year almost 2 million honey bee colonies—nearly two-thirds of the managed colonies in the United States—are loaded aboard semi-trailers and shipped across the country multiple times to …

New RT25 Data Will Help Beekeepers and
Farmers Protect Pollinators

EPA is updating its Residual Time to 25% Bee Mortality (RT25) Data table with information the agency has collected since the table was first published in 2014. EPA published the RT25 data as one of many actions we have taken since 2006 to protect pollinators. RT25 data help farmers and beekeepers know about how long a specific pesticide may remain toxic …

Scientists Find Evidence of 27 New Viruses in Bees

We’ve all heard of Deformed Wing Virus and most of you can probably list another 3 or 4 honey bee viruses. But what other viruses still lurk undiscovered? An international team of researchers uncovered evidence of 27 previously unknown viruses in bees. The finding could help scientists design strategies to prevent the spread of viral pathogens among these important pollinators."Populations …

Raiding the Rape Field

Honey bees can produce vast amounts of honey off canola, known as oilseed rape in Europe. It’s an early flow that can crystallize in the comb if the weather turns cool. Some beekeepers lately have become hesitant about placing their colonies near canola, worried that the pollen from treated fields is negatively impacting honey bee health. New research shows that …

What Gives Bees their Sweet Tooth?

Scientists have discovered bees linger on a flower, emptying it of nectar, because they have sugar-sensing taste neurons which work together to prolong the pleasure of the sweetness.Newcastle University researchers report that the bees' taste neurons found on their proboscis - their mouthparts - fire intense signals for up to 10 seconds - much longer than the taste neurons found …

Honey Bees Struggle to Find Enough Good Bacteria

Modern monoculture farming, commercial forestry and even well-intentioned gardeners could be making it harder for honey bees to store food and fight off diseases, a new study suggests.Human changes to the landscape, such as large areas of monoculture grassland for livestock grazing, and coniferous forests for timber production, is affecting the diversity of the 'microbiome' associated with the long-term food …

New Pesticide as Alternative to Neonicotinoids

In February 2018, the European Food Safety Authority (EFSA) confirmed that the pesticide group of neonicotinoids is harmful to bees. A novel pesticide manufactured by Bayer AG is therefore being discussed as an alternative; it contains flupyradifurone from the class of butenolides. The product goes by the brand name of Sivanto.Sivanto is assumed to be effective against various sucking insects …
