Bees living in suburban habitats are still being exposed to significant levels of pesticides despite the EU ban on the use of neonicotinoid pesticides on flowering crops, new research from University of Sussex scientists shows. While the introduction of new EU restrictions on the use of neonicotinoid chemicals five years ago has reduced exposure of … More Study shows EU pesticide ban failing to protect suburban bees.
The number of honey bee colonies fell by 16% in the winter of 2017-18, according to an international study led by the University of Strathclyde. The survey of 25,363 beekeepers in 36 countries found that, out of 544,879 colonies being managed at the start of winter, 89124 were lost, through a combination of circumstances including … More Honey bee colonies down by 16 percent.
Honey bee colony collapse has devastating consequences for the environment, the global economy, and food security worldwide. The culprits behind some of the destruction — parasitic Varroa mites — are just a couple of millimeters in size, and they infiltrate colonies and infect bees with viruses. Yet surprisingly little is known about the mite’s biology. Researchers from … More Genomes of parasitic mites harming the world’s bees.
Beekeepers across the United States lost 40.7% of their honey bee colonies from April 2018 to April 2019, according to preliminary results of the latest annual nationwide survey conducted by the University of Maryland-led nonprofit Bee Informed Partnership. Honey bees pollinate $15 billion worth of food crops in the United States each year. The survey … More U.S. beekeepers lost over 40 percent of colonies last year, the highest winter losses ever recorded. Results point to a need for increased research, extension, and best management practices.
Varroa mites do not feed on bee blood (hemolymph fluid) Research by scientists at the Agricultural Research Service (ARS) and the University of Maryland released today sheds new light — and reverses decades of scientific dogma — regarding a honey bee pest (Varroa destructor) that is considered the greatest single driver of the global honey … More Microscopy research helps unravel the workings of a major honey bee pest.
Researchers at the University of Sydney have found that the relationship between the tissue-sucking Varroa mite and virulence of a virus of honey bees, has most likely been misunderstood. The study challenges the long-held belief that the parasitic Varroa mite — a mite that sucks the tissue of honey bees — transmits the Deformed Wing Virus of honeybees … More Dangerous bee virus might be innocent bystander. Beekeepers urged to rethink fears around deadly virus.
Mycelium extract reduces viruses in honey bees. A mushroom extract fed to honey bees greatly reduces virus levels, according to a new paper from Washington State University scientists, the USDA and colleagues at Fungi Perfecti, a business based in Olympia, Washington. In field trials, colonies fed mycelium extract from amadou and reishi fungi showed a 79-fold reduction in … More Fungus provides powerful medicine in fighting honey bee viruses.
