Bees Don't Always Listen to the Hive

Posted by External 18 days ago General
http://www.enn.com — 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 34 days ago General
http://feeds.sciencedaily.com — 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 35 days ago General
http://feeds.sciencedaily.com — 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 39 days ago General
http://feeds.sciencedaily.com — 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

Pesticide impairs bees' ability to forage

Posted by External 42 days ago General
http://www.enn.com — 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

Taking account of environment of bees to better evaluate insecticide-related risks

Posted by External 46 days ago General
http://feeds.sciencedaily.com — The level of sensitivity of bees to the adverse effects of pesticides varies as a function of environmental conditions, research shows. Scientists observed that a neonicotinoid insecticide disturbed their ability to find their bearings, particularly in a complex landscape and under unfavorable weather conditions. Read More
