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 ...
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 ...
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 ...
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 ...
Researchers ID queens, mysterious disease syndrome as key factors in bee colony deaths
(Phys.org) —A new long-term study of honey bee health has found that a little-understood disease study authors are calling "idiopathic brood disease syndrome" (IBDS), which kills off bee larvae, is the ...
Honey bees fight back against Varroa
The parasitic mite Varroa destructor is a major contributor to the recent mysterious death of honey bee (Apis mellifera) colonies. New research published in BioMed Central's open access journal Genome Biolog ...
Biologists tag 'zombees' to track their flight
After last year's accidental discovery of "zombie"-like bees infected with a fly parasite, SF State researchers are conducting an elaborate experiment to learn more about the plight of the honey bees.
Deformed Wing Virus in honey bees transmitted by mites: study
Researchers in Hawaii and the UK report that the parasitic 'Varroa' mite has caused the Deformed Wing Virus (DWV) to proliferate in honey bee colonies.
Commonly used pesticide turns honey bees into 'picky eaters'
Biologists at UC San Diego have discovered that a small dose of a commonly used crop pesticide turns honey bees into "picky eaters" and affects their ability to recruit their nestmates to otherwise good sources of food.
Increased honey bee diversity means fewer pathogens, more helpful bacteria
A novel study of honey bee genetic diversity co-authored by an Indiana University biologist has for the first time found that greater diversity in worker bees leads to colonies with fewer pathogens and more ...
