'Honey bee health' of concern at Western Apicultural Society conference

Honey bee specialists and native pollinator experts will address the 31st annual Western Apicultural Society (WAS) Conference, set Aug. 17-20 in Healdsburg, Sonoma County. The main conference sessions will take place in the Dry Creek Inn and Krug Event Center, 198 Dry Creek Road. "The conf...

Live-in domestics: Mites as maids in tropical rainforest sweat bee nests

Mites not only inhabit the dust bunnies under the bed, they also occupy the nests of tropical sweat bees where they keep fungi in check. Bees and their young are healthier when mites live-in, report researchers from the Smithsonian Tropical Research Institute in Panama and the University of Texas ...

A cure for honey bee colony collapse?

For the first time, scientists have isolated the parasite Nosema ceranae (Microsporidia) from professional apiaries suffering from honey bee colony depopulation syndrome. They then went on to treat the infection with complete success. In a study published in the new journal from the Society f...

Bee smart, bee healthy

Bumblebee colonies which are fast learners are also better able to fight off infection, according to scientists from Queen Mary, University of London and the University of Leicester. Dr Nigel Raine from Queen Mary's School of Biological and Chemical Sciences, and Akram Alghamdi, Ezio Rosato and...

Springer bee expert Juergen Tautz wins prize for public communication

Juergen Tautz will receive a special discretionary prize as part of the 2008 European Molecular Biology Organization (EMBO) Award for Communication in the Life Sciences. The award was made in recognition of Tautz's long-term public communication activity on a single organism using all available m...

Pesticide build-up could lead to poor honey bee health

Honey bees industriously bring pollen and nectar to the hive, but along with the bounty comes a wide variety of pesticides, according to Penn State researchers. Add the outside assault to the pesticides already in the waxy structure of the hive, and bee researchers see a problem difficult to evalu...

New bee checklist lets scientists link important information about all bee species

In time for National Pollinator Week, June 22 through June 28, biologists have completed an online effort to compile a world checklist of bees. They have identified nearly 19,500 bee species worldwide, about 2,000 more than previously estimated. There is a current crisis known as "colony collapse ...

For honey bee queens, multiple mating makes a difference

The success of the reign of a honey bee queen appears to be determined to a large degree by the number of times she mates with drone bees. That is what research by scientists in the Department of Entomology and W.M. Keck Center for Behavioral Biology at North Carolina State University suggests...

A young brain for an old bee

We are all familiar with the fact that cognitive function declines as we get older. Moreover, recent studies have shown that the specific kind of daily activities we engage in during the course of our lives appears to influence the extent of this decline. A team of researchers from Technische Univ...

Flight of the bumble (and honey) bee

CARBONDALE, ILInsects such as honeybees and bumble bees are predictable in the way they move among flowers, typically moving directly from one flower to an adjacent cluster of flowers in the same row of plants. The bees' flight paths have a direct affect on their ability to hunt for pollen and gen...

Building a better bee

DAVIS, CALIF. A UC Davis researcher known for her honey bee line "New World Carniolans" has crossed her bees with their Old World counterparts to enhance their positive characteristics. "The bees are very gentle, very hygienic and very productive, and hopefully will confer increased resistance...

Two studies on bee evolution reveal surprises

The discovery of a 100-million-year old bee embedded in amber -- perhaps the oldest bee ever found -- "pushes the bee fossil record back about 35 million years," according to Bryan Danforth, Cornell associate professor of entomology. Danforth and George Poinar of Oregon State University found the...

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 Cornell study published in the Jan. 7 issue of the Proceedings ...

Honey bee genome holds clues to social behavior

By studying the humble honey bee, researchers at the University of Illinois at Urbana-Champaign have come a step closer to understanding the molecular basis of social behavior in humans. "The honey bee (Apis millifera) has been called a model system for social behavior," said Saurabh (pronounced ...

Scientists identify 36 genes, 100 neuropeptides in honey bee brains

From humans to honey bees, neuropeptides control brain activity and, hence, our behaviors. Understanding the roles these peptides play in the life of a honey bee will assist researchers in understanding the roles they play in their human counterparts. There are a million neurons in the brain of a...

Looking to a new era in bee research

A respected UK entomology journal, Insect Molecular Biology, today publishes its Honey Bee Genome Special Issue, timed to coincide with the release of the long-awaited Honey Bee Genome Sequence, published earlier this week in Nature magazine.

Mayan stingless bee keeping: Going, going, gone?

Long before Europeans brought honey bees (Apis mellifera) to the Americas, Mayan bee keepers harvested honey from the log nests of stingless bees native to tropical forests.

Bee mites suppress bee immunity, open door for viruses and bacteria

A non-native bee mite is causing the dramatic and sudden collapse of bee colonies across the country, but Penn State researchers believe they have found the combination of factors that triggers colony deaths which includes suppression of the bee immune system by the mites. The Varroa destructor ...
