Bees Throw Out Mites
Honey bees are now fighting back aggressively against Varroa mites, thanks to Agricultural Research Service (ARS) efforts to develop bees with a genetic trait that allows them to more easily find the mites ...
Honey bees use multiple genetic pathways to fight infections
Honey bees use different sets of genes, regulated by two distinct mechanisms, to fight off viruses, bacteria and gut parasites, according to researchers at Penn State and the Georgia Institute of Technology.
Manganese speeds up honey bees
Asked to name one way people have changed the environment, many people would probably say "global warming." But that's really just the start of it.
'Stressed' young bees could be the cause of colony collapse
Colony Collapse Disorder (CCD) is a major threat to bee colonies around the world and affects their ability to perform vital human food crop pollination. It has been a cause of urgent concern for scientists ...
Researchers confirm that neonicotinoid insecticides impair bee's brains
Research at the Universities of St Andrews and Dundee has confirmed that levels of neonicotinoid insecticides accepted to exist in agriculture cause both impairment of bumblebees' brain cells and subsequent ...
Scientists track gene activity when honey bees do and don't eat honey
Many beekeepers feed their honey bees sucrose or high-fructose corn syrup when times are lean inside the hive. This practice has come under scrutiny, however, in response to colony collapse disorder, the ...
Research trio suggest certain bee populations could be key to food security
Pesticides impair bees' ability to gather food, researchers find
(Phys.org) —Controversial pesticides ingested by bumble bees can seriously impact the insects' ability to collect food, even at very low levels of contamination, says new research from the University of ...
Molecular evolution of genetic sex-determination switch in honeybees
It's taken nearly 200 years, but scientists in Arizona and Europe have teased out how the molecular switch for sex gradually and adaptively evolved in the honeybee.
New research provides evolutionary snapshot of surprisingly altruistic bees
(Phys.org) —A paper published today in Current Biology demonstrates that even in the hopeless situation of colony collapse, queenless honeybees will still show remarkable altruism towards their colony, defend ...
Bees under threat from disease-carrying bumblebee imports, research reveals
Stricter controls over bumblebee imports to the UK are urgently required to prevent diseases spreading to native bumblebees and honeybees, scientists have warned. The call follows the discovery of parasites in over three-quarters ...
Lonely bees make better guests
Solitary bees are twice as likely to pollinate the flowers they visit as their more sociable counterparts, according to a new study.
Researchers find genetic diversity key to survival of honey bee colonies
When it comes to honey bees, more mates is better. A new study from North Carolina State University, the University of Maryland and the U.S. Department of Agriculture (USDA) shows that genetic diversity is ...
US report: Many causes for dramatic bee disappearance (Update)
A new U.S. report blames a combination of problems for a mysterious and dramatic disappearance of honeybees across the country since 2006.
