Flying doctor bees to prevent cherry disease

Posted by External 27 days ago General — A method to use bees to deliver disease control to cherry blossom, preventing brown rot in cherries, is being introduced by researchers. "Brown rot is caused by a fungus that significantly impacts the cherry industry through costs of applying fungicide, yield loss and fruit spoilage," says the project's leader and bee researcher.

Of bees, mites, and viruses: Virus infections after arrival of new parasitic mite in New Zealand honeybee colonies

Posted by External 62 days ago General — Honeybee colonies are dying at alarming rates worldwide. A variety of factors have been proposed to explain their decline, but the exact cause -- and how bees can be saved -- remains unclear. A new article examines the viral landscape in honeybee colonies in New Zealand after the recent arrival of the parasitic Varroa destructor mite. Read More

Bees Don't Always Listen to the Hive

Posted by External 75 days ago General — Honey bees are known for their fascinating social structure. A honey bee colony is in fact a well-organized machine, running on good communication, defense and division of labor. As social insects, honey bees have also been shown the communicate to their fellow foragers, a dance to tell their counterparts where food is located. But listening to other bees isn’t always the name of the game. Read More

Vasculature of the hive: How honey bees stay cool

Posted by External 91 days ago General — Honey bees, especially the young, are highly sensitive to temperature and to protect developing bees, adults work together to maintain temperatures within a narrow range. New research also supports the theoretical construct of the bee hive as a superorganism — an entity in which its many members carry out specialized and vital functions to keep the whole functioning as a unit.

Radio frequency ID tags on honey bees reveal hive dynamics

Posted by External 92 days ago General — Scientists attached radio-frequency identification tags to hundreds of individual honey bees and tracked them for several weeks. The effort yielded two discoveries: Some foraging bees are much busier than others; and if those busy bees disappear, others will take their place. Read More

Best for bees to be stay-at-homes: Imported bees don't do as well as locals

Posted by External 96 days ago General — Bees born in the local area manage better than bees imported from elsewhere, a study has shown. "Many beekeepers believe that it is best to buy queens from outside instead of using the queens they have in their own beehives. However, there is increasing evidence that the global honey bee trade has detrimental effects, including the spread of new diseases and pests," says one expert. Read More

For bees and flowers, tongue size matters

Posted by External 98 days ago General — When it comes to bee tongues, length is proportional to the size of the bee, but heritage sets the proportion. Estimating this hard to measure trait helps scientists understand bee species' resiliency to change. Read More

Pesticide impairs bees' ability to forage

Posted by External 99 days ago General — A study that involved fitting bumblebees with tiny radio frequency tags found long-term exposure to a neonicotinoid pesticide hampers bees' ability to forage for pollen. The research by Nigel Raine, a professor at the University of Guelph, and Richard Gill of Imperial College, London, shows how long-term pesticide exposure affects individual bees' day-to-day behaviour, including pollen collection Read More
