Results point to a need for increased research, extension, and best management practices. 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 … More U.S. beekeepers lost over 40 percent of colonies last year, highest winter losses ever recorded.
Wild bees in Europe are in trouble — more than 50 percent of local species are now classified as endangered. Recent findings indicate that, in farming areas, species that emerge in late summer are most acutely threatened. The pollination services provided by wild bees are indispensable, not only for ecological but also for eminently economic … More Insects in decline: On farmland, latecomers lose out.
Adjuvants not as benign as previously thought A new article reveals that adjuvants, chemicals commonly added to pesticides, amplify toxicity affecting mortality rates, flight intensity, colony intensity, and pupae development in honey bees. Adjuvants are chemicals that are commonly added to plant protection products, such as pesticides, to help them spread, adhere to targets, disperse … More Pesticides deliver a one-two punch to honey bees.
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 … More Fungus provides powerful medicine in fighting honey bee viruses.
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.
