Colony collapse disorder (CCD) is an abnormal phenomenon that occurs when the majority of worker bees in a honey bee colony disappear, leaving behind a queen, plenty of food, and a few nurse bees to care for the remaining immature bees. [1]
Colony collapse disorder has attracted much public attention. According to a 2013 blog the winter losses of beehives had increased in recent years in Europe and the United States, with a hive failure rate up to 50%. [19]
Varroa in combination with viral vectors and bacteria have been theoretically implicated in colony collapse disorder. [ citation needed ] It is known that thymol , a compound produced by thyme , naturally occurring in thyme honey, is a treatment for Varroa , though it may cause bee mortality at high concentrations. [ 2 ]
Detected in the early 21st century, a threat in this direction is colony collapse disorder, [40] a phenomenon that might foreshadow the imminent extinction [41] of the Western honeybee. As the bee plays a vital role in pollination, its extinction would severely disrupt the food chain.
North American and European populations were severely depleted by Varroa mite infestations during the early 1990s, and U.S. beekeepers were further affected by colony collapse disorder in 2006 and 2007. [81] Some subspecies of Apis mellifera show naturally varroa sensitive hygiene, for example Apis mellifera lamarckii [82] and Apis mellifera ...
Gray goo (also spelled as grey goo) is a hypothetical global catastrophic scenario involving molecular nanotechnology in which out-of-control self-replicating machines consume all biomass (and perhaps also everything else) on Earth while building many more of themselves, [1] [2] a scenario that has been called ecophagy (literally: "consumption of the environment"). [3]
The story is centered on the sudden disappearance of honey bees from beehives around the world, caused by the poorly understood phenomenon known as colony collapse disorder or CCD. Although the film does not draw any firm scientific conclusions as to the precise cause or causes of CCD, it does suggest a link between neonicotinoid pesticides and ...
David Hackenberg is an American commercial beekeeper [1] [2] who started Hackenberg Apiaries which runs beehives in several American states.. Hackenberg witnessed the first case of what was going to be known as Colony Collapse Disorder (CCD) in November 2006 and reported it publicly in February 2007.
