The study, conducted by researchers at North Carolina State University and the University of Massachusetts Amherst, showed that two different species of bees fed a diet of sunflower pollen had dramatically lower rates of infection by specific pathogens. Bumble bees on the sunflower diet also had generally better colony health than bees fed on diets … More Sunflower pollen has medicinal, protective effects on bees.
A new tool from the Agricultural Research Service (ARS) can predict the odds that honey bee colonies overwintered in cold storage will be large enough to rent for almond pollination in February. Identifying which colonies will not be worth spending dollars to overwinter can improve beekeepers’ bottom line. Beekeepers have been losing an average of 30 percent of overwintered … More New tool improves beekeepers’ overwintering odds and bottom line.
The European Union banned dangerous neonicotinoid pesticides more than TWO YEARS AGO, knowing they contribute to mass pollinator deaths. So why does the U.S. still use them? Because they make big money for corporations like Bayer-Monsanto. These and other Big Polluters are driving bumblebees, monarch butterflies and countless other pollinators to the brink of mass extinction. We cannot let … More Over 1 BILLION. That’s how many pounds of lethal pesticides we spray every year. More than 1 billion pounds of toxic chemicals that kill pollinators and endanger our food supply.
Scientists at UBC are unravelling the mysteries behind a persistent problem in commercial beekeeping that is one of the leading causes of colony mortality — queen bee failure. This occurs when the queen fails to produce enough fertilized eggs to maintain the hive, and is regularly cited by the Canadian Association of Professional Apiarists as … More Scientists find clues to queen bee failure.
More “intensive” beekeeping does not raise the risk of diseases that harm or kill the insects, new research suggests. Intensive agriculture — where animals or plants are kept crowded together in very high densities — is thought to result in higher rates of disease spreading. But researchers from the University of Exeter and the University … More ‘Intensive’ beekeeping not to blame for common bee diseases.
The reddish-brown varroa mite, a parasite of honeybees and accidentally introduced in the Big Island of Hawaii in 2007-08, is about the size of a pinhead. Yet, its effects there are concerning to entomologists because the mite is found nearly everywhere honeybees are present. A team led by entomologists at the University of California, Riverside, … More Bee mite arrival in Hawaii causes pathogen changes in honeybee predators.
A new study from Northwestern University and the Chicago Botanic Garden has found that climate change may drive local extinction of mason bees in Arizona and other naturally warm climates. In a two-year, in situ field experiment that altered the temperature of the bees’ nests to simulate a warmer, future climate, 35 percent of bees … More Climate change linked to potential population decline in bees.
For the first time ever, scientists have documented a widespread extinction of bees that occurred 65 million years ago, concurrent with the massive event that wiped out land dinosaurs and many flowering plants. Their findings, published this week in the journal PLOS ONE, could shed light on the current decline in bee species. Lead author Sandra … More Bees underwent massive extinctions at the same time as the dinosaurs.
A coalition that includes Environmental Defence and the Ontario Beekeepers Federation says proposed rule changes for neonicotinoids, or neonics for short, will make it easier for farmers to use them and harder for the government to track them. But the Ontario government, farmer organizations and pesticide manufacturers who support the changes say they would reduce … More Environmental groups say the Ontario government is proposing to weaken the province’s restrictions on a class of agricultural pesticides that some scientific studies blame for large declines in the populations of bees and other insects.
The immediate “no-regret” measures they propose include aggressively curbing planet-heating emissions and the use of synthetic pesticides. by Jessica Corbett, staff writer Highlighting the “strong scientific consensus that the decline of insects, other arthropods, and biodiversity as a whole, is a very real and serious threat that society must urgently address,” 73 international scientists on … More ‘Because Insects Are Key to Our Own Survival,’ 73 Scientists Unveil Global Road map to Battle Bugpocalypse.
