This week, USDA and its partners released the results of the eight annual national survey of honey bee losses. The survey shows good news—fewer honey bee colonies were lost this winter than in previous years. According to survey results, total losses of managed honey bee colonies from all causes were 23.2 percent nationwide.
That figure is a significant improvement over the 30.5 percent loss reported last winter, but it is still higher than the eight-year average loss of 29.6 percent and still far above the 18.9 percent level of loss that beekeepers say is acceptable for their economic sustainability.
While we’re pleased to see improvement this year, these losses are still too high. Read more »
Click to visit the USDA's 24/7 bee watch camera.
At the ribbon cutting of the USDA Headquarters People’s Garden in April 2010 plans were already in place to install a beehive on the roof of the Whitten Building as well as a “bee-cam” so anyone anywhere could learn about bee activity. USDA’s newest ‘buzzing’ residents were welcomed on Earth Day but the bee cam was put on hold. 18 gallons of honey later, that idea has finally come to bee. You can now #USDABeeWatch 24/7 at www.usda.gov/beewatch.
So what will you see on our bee cam? This time of year, the camera – placed several feet from the entrance of the hive – shows female worker bees entering and exiting the hive gathering nectar and pollen (both collected from flowers) to convert into honey. Be on the lookout for bees carrying a load of pollen on their hind legs. As bees groom, they’ll move the pollen onto their back legs creating a pellet of pollen. A small amount of nectar is used to stick the dry pollen together. Read more »
The black dot on this honey bee is a varroa mite--a parasite that sucks vital fluids like a tick, although it also acts like a mosquito transmitting viruses and other pathogens to the bee.
This post is part of the Science Tuesday feature series on the USDA blog. Check back each week as we showcase stories and news from the USDA’s rich science and research portfolio.
You’ve probably heard that the honey bees in this country are in trouble, with about one-third of our managed colonies dying off every winter. Later this week, we will learn how the honey bees survived this winter. With severe weather in a number of areas in the U.S. this winter, a number of us concerned about bees will be closely watching the results.
While scientists continue work to identify all the factors that have lead to honey bee losses, it is clear that there are biological and environmental stresses that have created a complex challenge that will take a complex, multi-faceted approach to solve. Parasites, diseases, pesticides, narrow genetic diversity in honey bee colonies, and less access to diverse forage all play a role in colony declines. To confront this diverse mix of challenges, we require a mix of solutions – the odds are that we won’t find one magic fix to help our honey bees. Read more »
This month USDA will be highlighting the value of conservation with a different focus each week.
Sometimes the benefits of conservation can be abstract. For example, think a minute about the dollar value of a single tree. Can you come up with a number?
Did you consider that the tree creates oxygen, captures carbon and provides wildlife habitat? Or that the tree serves as a windbreak, shades and cools the surrounding area, and improves water quality? Don’t forget, these benefits extend for many decades over the lifetime of a healthy tree.

When Jake and Jondra Shadowen from Benton, Ky. got married 14 years ago, they decided to buy a 26-acre ranch with a goal of raising a healthy herd of cattle. Today, thanks to hard work and conservation, they maintain a strong herd of 26 cattle, up from 11 when they first began.
They worked with USDA’s Natural Resources Conservation Service to implement a rotational grazing system, which breaks up large pastures into smaller ones. A rotational grazing system allows for grass to grow faster and quicker and prevents soil from becoming prone to erosion. Read more »
Little brown bats, like these found in a cave in Maine in 2013, are increasingly being found with white-nose syndrome. The U.S. Forest Service is researching many angles to help wildlife managers and the public to combat the disease. (U.S. Fish and Wildlife Service)
Take a moment to look at the night sky and watch the swift flight of bats on their daily mission as they dart through your backyard or forest. Now, think about how it’s becoming harder to spot these winged wonders, and ask why. The answer: The quickly growing spread of a disease known as white-nose syndrome has been decimating bat populations, as explained in a recently released film on the subject.
This increasingly devastating disease has killed more than six million bats in just six years, a serious problem for a creature that provides so many benefits to the environment – as both a plant pollinator and as a major predator in keeping insect populations in check. Read more »
