Up to a third of our food supply depends on pollination by domesticated honeybees, but the insects are up to five times more efficient when wild bees buzz the same fields. (2006-09-21)

Tree cavities for wild honeybees
The forests in Europe provide habitat for around 80,000 colonies of wild honeybees. That is why more attention should be paid to preserving the nesting sites for these threatened insects, according to researchers. (2019-12-11)

'Intensive' beekeeping not to blame for common bee diseases
More 'intensive' beekeeping does not raise the risk of diseases that harm or kill the insects, new research suggests. (2019-07-17)

Honeybee mite raises bumblebee virus risk
A mite that spreads a dangerous virus among honeybees also plays an indirect role in infecting wild bumblebees, new research shows. (2019-06-12)

Queen bee promiscuity boosts hive health
Though promiscuity may be risky behavior for humans, it's healthy for honeybees: Queen honeybees who indulge in sexual surfeits with multiple drones produce more disease-resistant colonies than monogamous monarchs, according to a new study. (2006-12-08)

New study reveals widespread risk of infectious diseases to wild bees
Researchers have discovered a network of viruses, which were previously associated with managed honeybees, may now pose a widespread risk to bumblebees in the wild, according to a new study published Wednesday, March 4, in the Journal of Animal Ecology. (2015-03-04)

Pesticides not yet proven guilty of causing honeybee declines
The impact of crop pesticides on honeybee colonies is unlikely to cause colony collapse, according to a paper in the journal Science. More research is now needed to predict the impact of widely-used agricultural insecticides, called neonicotinoids, on honeybee populations. UK scientists highlight flaws in previous research that predicted that neonicotinoids could cause honeybee colony collapse. Neonicotinoids are among the most widely-used agricultural insecticides and honeybees ingest residues of the pesticides as they gather nectar and pollen from treated plants. (2012-09-20)

Another species of Varroa mite threatens European honeybees
A sister species of the Varroa destructor mite is developing the ability to parasitize European honeybees, threatening pollinators already hard pressed by pesticides, nutritional deficiencies and disease, a Purdue University study says. (2016-11-17)

How honeybees do without males
An isolated population of honeybees, the Cape bees, living in South Africa has evolved a strategy to reproduce without males. A research team from Uppsala University has sequenced the entire genomes of a sample of Cape bees and compared them with other populations of honeybees to find out the genetic mechanisms behind their asexual reproduction. (2016-06-09)

Diesel exhaust stops honeybees from finding the flowers they want to forage
Exposure to common air pollutants found in diesel exhaust pollution can affect the ability of honeybees to recognize floral odors, new University of Southampton research shows. (2013-10-03)

Detecting poisons in nectar is an odour-ous task for honeybees
Though many spring flowers have bright advertisements offering sweet rewards to honeybees, some common flowers have not-so-sweet or even toxic nectars. Why plants would try to poison the honeybees they wish to attract is a scientific mystery. Can honeybees learn whether nectar contains toxins, and does this influence their ability as pollinators? Dr. Geraldine Wright from Newcastle University will present data on how toxins in nectar affect a honeybee's willingness to eat floral nectar. (2007-03-31)

Banned EU pesticide affects learning of honeybees but not bumblebees
Scientists have discovered that a banned EU pesticide affects the learning of honeybees but not bumblebees. This has important implications for global regulatory assessments because they generally use honeybees as a model for all bees. (2016-04-06)

Fipronil and imidacloprid reduce honeybee mitochondrial activity
New research published in Environmental Toxicology and Chemistry addresses the effects of fipronil and imidacloprid on honeybees. While damage at sublethal levels may not be evident, low level exposure inhibits the ability to forage and return to the hive, which could result in declining bee populations. (2014-08-06)

New study suggests severe deficits in UK honeybee numbers
A study published by the University of Reading's Centre for Agri-Environmental Research suggests that honeybees may not be as important to pollination services in the UK than previously supposed. The research was published in the journal Agriculture, Ecosystems and Environment. (2011-07-01)

Managed honeybees linked to new diseases in wild bees
Diseases that are common in managed honeybee colonies are now widespread in the UK's wild bumblebees, according to research published in Nature. The study suggests that some diseases are being driven into wild bumblebee populations from managed honeybees. (2014-02-19)

Bee challenged -- toxin-laden nectar poses problems for honeybees
Researchers at Newcastle University have shown for the first time that chemical seratonin enables the honeybee to learn to avoid nectar containing toxins. (2010-12-20)

Evolutionary history of honeybees revealed by genomics
In a study published in Nature Genetics, researchers from Uppsala University present the first global analysis of genome variation in honeybees. The findings show a surprisingly high level of genetic diversity in honeybees, and indicate that the species most probably originates from Asia, and not from Africa as previously thought. (2014-08-24)

Wild pollinators support farm productivity and stabilize yield
Eighty-four percent of European crops are dependent on insect pollination. The serious decline in managed honeybees and wild bees in Europe can cause yield decreases with threats to the environment and economy of Europe. To raise awareness, the EC FP7 STEP Project published a farmers' fact sheet in 15 European languages. It encourages utilizing the benefits of wild insect pollinators, reducing the risks of relying solely on honeybees for crop production. (2012-08-17)

Alien honeybees could cause plant extinction
New research indicates that introduced 'alien' honeybees are competing for resources with native bees and threatening the survival of plants that rely on interactions with specific pollinators. (2018-02-08)

Pesticide deadly to bees now easily detected in honey
A common insecticide that is a major hazard for honeybees is now effectively detected in honey thanks to a simple new method. (2020-11-24)

Honeybees infect wild bumblebees -- through shared flowers
Viruses in managed honeybees are spilling over to wild bumblebee populations though the shared use of flowers, a first-of-its-kind study reveals. This research suggests commercial apiaries may need to be kept away from areas where there are vulnerable native pollinator species, like the endangered rusty patched bumblebee. (2019-06-26)

Had your morning coffee? Thank a killer bee
Debunking the widely held belief that the self-pollinating shrub that produces the Arabica coffee bean has no use for insects, David W. Roubik of the Smithsonian Tropical Research Institute has demonstrated that pollination - particularly by non-native African honeybees - dramatically boosts the yield from coffee plants. The research emphasizes the importance of shade-grown coffee - not only to improve the flavor of the beverage, but also to maintain the habitat for naturalized honeybees and other pollinators. (2002-06-12)

Bumblebees get by with a little help from their honeybee rivals
Bumblebees can use cues from their rivals the honeybees to learn where the best food resources are, according to new research from Queen Mary, University of London. (2012-02-14)

Bee warned -- Study finds pesticides threaten native pollinators
A new Cornell study of New York state apple orchards finds that pesticides harm wild bees, and fungicides labeled 'safe for bees' also indirectly may threaten native pollinators. (2015-06-04)

This flower smells like a bee under attack
A new discovery takes plants' deception of their pollinators to a whole new level. Researchers reporting in Current Biology on Oct. 6 found that the ornamental plant popularly known as Giant Ceropegia fools certain freeloading flies into pollinating it by mimicking the scent of honeybees under attack. The flies find that smell attractive because they typically dine on the drippings of honeybees that are in the clutches of a spider or other predatory insect. (2016-10-06)

Cyprian honeybees kill their enemy by smothering them
For the first time, researchers have discovered that when Cyprian honeybees mob and kill their arch enemy, the Oriental hornet, the cause of death is asphyxiation. They reported their findings in the Sept. 18, 2007, issue of Current Biology, a publication of Cell Press. (2007-09-17)

A smelling bee?
If there were an international smelling bee, a deadly mite would be a favorite to win. (2015-06-03)

Changes in a vibration-sensitive neuron may equip forager honeybees for waggle dance communication, according to research recently published in eNeuro. (2019-08-26)

Hives ferment a yeasty brew, attract beetle pest
The honeybee's alarm signal may not only bring help, but also attract the small hive beetle. Now, an international team of researchers has found that small hive beetles can detect some alarm pheromones at levels below that detected by honeybees. (2007-05-16)

Stronger pesticide regulations likely needed to protect all bee species, say studies
Regulators worldwide currently use honeybees as the sole model species failing to account for potential threats posed by agrochemicals to the full diversity of bee species from bumblebees to solitary bees, which are probably more important for pollination of food crops than managed honeybees. They are potentially more vulnerable to pesticides given they nest in the ground and bumblebee queens have different life cycles that could increase exposure. (2018-12-11)

EMBO recognizes German zoologist for public communication
Juergen Tautz from the University of Wuerzburg will receive a special discretionary prize, as part of the 2008 EMBO Award for Communication in the Life Sciences. The European Molecular Biology Organization awards the prize annually to a practicing scientist in Europe for outstanding communication with the public. The additional award was made in recognition of Tautz's long-term public communication activity on a single organism using all available media. (2008-08-27)

Pesticides used to help bees may actually harm them
Honeybees from chlorothalanil-treated hives showed the greatest change in gut microbiome. (2016-08-08)

Think of honeybees as 'livestock,' not wildlife, argue experts
Contrary to public perception, die-offs in honeybee colonies are an agricultural not a conservation issue, argue Cambridge researchers, who say that manged honeybees may contribute to the genuine biodiversity crisis of Europe's declining wild pollinators. (2018-01-25)

Pollinators focus of international conference
The decline of pollinator populations around the world and the potential causes and cures for the decline will be the focus of the International Conference on Pollinator Biology, Health and Policy, July 24-28, 2010, Penn State's University Park campus. (2010-06-17)

How does a honeybee queen avoid inbreeding in her colony?
Recombination, or crossing-over, occurs when sperm and egg cells are formed and segments of each chromosome pair are interchanged. This process plays an crucial role in the maintenance of genetic variation. Matthew Webster and Andreas Wallberg at the Biomedical Centre, Uppsala University, have studied recombination in honeybees. The extreme recombination rates found in this species seem to be crucial for their survival. (2015-04-29)

Honeybee dance breaks down cultural barrier
Asian and European honeybees can learn to understand one another's dance languages despite having evolved different forms of communication, an international research team has shown for the first time. The findings are published this week in the journal PLoS ONE. (2008-06-03)

New orchid deception found: wearing the scent of hornet's prey
Orchids are famous for their deceptions. Most of those with nothing of value to offer their pollinators lure them instead with the scents of more rewarding flowers or potential mates. Now, a report published online on Aug. 6 in Current Biology, a Cell Press publication, reveals for the first time that a species of orchid, which lives on the Chinese island of Hainan, fools its hornet pollinator by issuing a chemical that honeybees use to send an alarm. (2009-08-06)

Honeybee dance dialects
Honeybees use their waggle dance to tell their conspecifics where to find food. Depending on the honeybee species, there are different dance dialects, as a German-Indian research team has shown. (2020-03-04)
