Bumblebees use nicotine to fight off parasites
Bumblebees that have been infected by parasites seek out flowers with nicotine in the nectar, likely to fight off the infection, new research has found. The nicotine appears to slow the progression of disease in infected bees but has harmful effects when consumed by healthy bees. (2015-04-27)

Old bees' memory fades; mirrors recall of mammals
A study published Oct. 19 in the open access journal Public Library of Science (PLoS) ONE, shows that not just human memories fade.

'Bee' informed: Public interest exceeds understanding in bee conservation
Many people have heard bee populations are declining due to such threats as colony collapse disorder, pesticides and habitat loss. And many understand bees are critical to plant pollination. Yet, according to a study led by Utah State University ecologist Joseph Wilson, few are aware of the wide diversity of bees and other pollinators beyond such species as honeybees. Because conservation efforts require substantial public support, outreach is needed to help people understand bee declines and how to protect pollinators. (2017-09-05)

Ground-nesting bees on farms lack food, grow smaller
According to a recent study, the size of a common ground-nesting bee -- an important crop pollinator -- has grown smaller in heavily farmed landscapes. (2016-03-24)

'Stressed' young bees could be the cause of colony collapse
Researchers have tracked the activity of bees forced to begin foraging earlier in their lives due to stress on their colonies and found that they collect less pollen and die earlier, accelerating the decline and collapse of their hives. (2015-02-09)

London bee tracking project begins
Hundreds of bees with individual colored number tags will be released from the rooftops of Queen Mary University of London on Tuesday, June 21, and over the next month for a project that hopes to uncover the secret lives of London's bees. (2016-06-20)

New orchid bee guide
A new guide to the orchid bees of tropical America is now available. Co-authored by David Roubik, Staff Scientist at the Smithsonian Tropical Research Institute in Panama, and Paul E. Hanson; published by Costa Rica's National Biodiversity Institute (INBio), this bilingual field guide provides a (2004-05-10)

Social bees mark dangerous flowers with chemical signals
Scientists already knew that some social bee species warn their conspecifics when detecting the presence of a predator near their hive, which in turn causes an attack response to the possible predator. Researchers at the University of Tours in collaboration with the Experimental Station of Arid Zones of Almeria have now demonstrated that they also use chemical signals to mark those flowers where they have previously been attacked. (2013-03-14)

Bumblebees copy one another when contending with unfamiliar flowers
Researchers have reported findings that offer a surprising new twist to our understanding of how bumblebees, a vital floral pollinator, select the flowers from which they collect nectar. When faced with unfamiliar plants, foraging bees do not choose flowers entirely alone but instead copy the choices of other bees. The new findings suggest that bees adjust their behavior when dealing with flowers of unfamiliar plant species. (2005-06-20)

Male bees have more than a one-track mind
Male bumblebees are just as smart as female worker bees despite their dim-witted reputation, according to new research from Queen Mary University of London. (2015-11-12)

Bumblebees learn the sweet smell of foraging success
Bumblebees use flower scent to guide their nest-mates to good food sources, according to scientists from Queen Mary, University of London. (2008-10-24)

Bumblebees differentiate flower types when arranged horizontally but not vertically
Bumblebees trained to go to feeders labelled with a certain color or pattern cue but avoid differently labelled alternative feeders did so when feeders were arranged horizontally but didn't when arranged vertically. Researchers believe this could be because groups of flowers arranged horizontally, like those in a meadow, often include several different species, while those arranged vertically, such as in blossoming trees are likely to all be the same species. (2015-04-07)

Promiscuous queen bees maintain genetic diversity
By mating with nearly 100 males, queen bees on isolated islands avoid inbreeding and keep colonies healthy. The results, published in the current issue of PLoS ONE, focused on giant honey bee colonies on Hainan Island, off the coast of China. Since these bees have long been separated from their continental cousins, it was thought that the island bees would be prime candidates for inbreeding as well as having very different genes, said Zachary Huang, Michigan State University entomologist. (2012-04-16)

Bumble bees prefer a low-fat diet
Are bees dying of malnourishment? Professor Sara Diana Leonhardt examines the interactions between plants and insects with her work group at the TUM School of Life Sciences Weihenstephan. Using behavioral experiments, her team analyzes how bumble bees evaluate the quality of food sources and how foods of various qualities affect their well-being. (2020-02-05)

Smells like bees' spirit
When bumblebees return to the nest from a successful foraging mission, they produce a pheromone which encourages their nest mates to also go out and find food. Scientists had originally thought that these pheromones elicited a standard response from all bees. But new research from Queen Mary's School of Biological and Chemical Sciences has shown that bees' response to the pheromone changes according to their situation. (2008-08-13)

Secret life of bees now a little less secret
Many plants produce toxic chemicals to protect themselves against plant-eating animals, and many flowering plants have evolved flower structures that prevent pollinators such as bees from taking too much pollen. Now ecologists have produced experimental evidence that flowering plants might also use chemical defenses to protect their pollen from some bees. The results are published next week in the British Ecological Society's journal Functional Ecology. (2011-02-01)

Research reveals why plant diversity is so important for bee diversity
A study in southern England reveals why bumble bees and honey bees thrive despite foraging on the same flowers. (2021-02-10)

Fear of predators drives honey bees away from good food sources
Honey bees live in a world filled with danger in which predators seize them from the sky and wait to ambush them on flowers. Such fear drives bees to avoid food sources closely associated with predators and, interestingly, makes colonies of bees less risk-tolerant than individual bees, according to a study published in this week's issue of the open-access journal PLOS ONE. (2013-10-02)

Scents and sense ability: Diesel fumes alter half the flower smells bees need
In polluted environments, diesel fumes may be reducing the availability of almost half the most common flower odours that bees use to find their food, research has found. (2015-10-19)

Scientists train honey bees to stick out their tongues
A new video-article in Journal of Visualized Experiments illustrates a novel tactile conditioning experiment using honey bees. The technique, presented by the lab of Dr. Volker Dürr of Bielefeld University, trains honey bees to stick out their tongues when their antennae touch an object. This procedure allows researchers to analyze how changes in antennal movement correspond to tactile pattern recognition and learning. (2012-12-12)
