Honey bee populations have been mysteriously falling for at least five years in the United States, but the cause of so-called colony collapse disorder (CCD) is still largely unknown. In a report published Nov. 2 in the online journal PLoS ONE, researchers report that a widely used in-hive medication may make bees more susceptible to toxicity of commonly used pesticides, and that this interaction may be at least partially responsible for the continuing honey bee population loss. The...

The World Organization for Animal Health (OIE) said Wednesday that the dramatic die-off of honey bees around the world, threatening crops that rely on the insects for pollination, is not due to any one single factor. The OIE said that a host of issues are plaguing the honey bees - including parasites, viruses, bacterial infections, pesticides, and poor nutrition resulting from the impact of human activities on the environment. Bee colonies naturally lose about 5 percent of their populations...

Ground-breaking discoveries by Michigan State University researchers could help protect honeybees from deadly parasites that have devastated commercial colonies. The MSU researchers for the first time were able to produce in the laboratory proteins that help channel sodium ions through cell membranes of parasites known as Varroa mites. The research, using cellular frog eggs, also found that these proteins react to chemicals differently than the sodium channel proteins in honeybees, a finding...

Attendees of this year's Apimondia, the 41st world apiculture congress, in southern France are focusing on what is killing the world's bees. Pesticides, viruses, industrialized farming and fungus are among the possible reasons why bee hives throughout parts of North America, Europe, and Asia have been struck by a mysterious ailment known as Colony Collapse Disorder (CCD).  Although bee communities naturally lose around five percent of their numbers during normal times, up to 90 percent...

Damage to the honey bee's internal protein-producing "factories" may provide researchers with a new clue to the sudden collapse of honey bee colonies across the nation. Colony collapse disorder is a phenomenon in which worker bees from beehives or colonies abruptly disappear. These disappearances have been happening since the dawn of apiculture, but the term "Ëœcolony collapse disorder' was first used to describe a drastic increase in the number of disappearances of Western honey...

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 for Applied Microbiology: Environmental Microbiology Reports, scientists from Spain analyzed two apiaries and found evidence of honey bee colony depopulation syndrome (also known as colony collapse...

In Britain, the honey bee population is on the decline, which has led to the prediction that the country will run out of English honey by Christmas. But what's more important is the effect this decline will have on farmers in the region. "We are extremely aware of the enormous threat there is to honey bees and the huge reduction in population," said Adrian Barlow, chief executive of trade group English Apples and Pears. "It is something we are very concerned about." Honey bees have the...

It's about bee-ing all they can be. An enhanced-line honey bee stock developed by University of California, Davis bee breeder-geneticist Susan Cobey, that crosses her bee line "New World Carnolians" with "Old World" Carnolians from Germany, shows genetic promise in aiding the troubled bee industry, research reveals. "I'm really pleased with the stock," said Cobey, project leader of a honey bee stock improvement grant, funded by the California State Beekeepers' Association and the...

One of the biggest world wide threats to honey bees, the varroa mite, could soon be about to meet its nemesis. Researchers at the University of Warwick are examining naturally occurring fungi that kill the varroa mite. They are also exploring a range of ways to deliver the killer fungus throughout the hives from bee fungal foot baths to powder sprays. It well known that bees world wide are suffering serious declines and one of the causes of that decline is the varroa mite, Varroa destructor....


Word of the Day
tesla
  • The unit of magnetic flux density in the International System of Units, equal to the magnitude of the magnetic field vector necessary to produce a force of one newton on a charge of one coulomb moving perpendicular to the direction of the magnetic field vector with a velocity of one meter per second. It is equivalent to one weber per square meter.
This word is named for Nikola Tesla, the inventor, engineer, and futurist.
