Counting the Vanishing Bees
No census exists so far, but a new monitoring method involving pan traps is remarkably cheap and efficient.http://en.wikipedia.org/wiki/Colony_collapse_disorder
Colony collapse disorder
From Wikipedia, the free encyclopedia
Colony collapse disorder (CCD) is a phenomenon in which worker bees from a beehive or European honey bee colony abruptly disappear. While such disappearances have occurred throughout the history of apiculture, the term colony collapse disorder was first applied to a drastic rise in the number of disappearances of Western honey bee colonies in North America in late 2006.[1] Colony collapse is significant economically because many agricultural crops worldwide are pollinated by bees; and ecologically, because of the major role that bees play in the reproduction of plant communities in the wild.European beekeepers observed similar phenomena in Belgium, France, the Netherlands, Greece, Italy, Portugal, and Spain,[2] and initial reports have also come in from Switzerland and Germany, albeit to a lesser degree[3] while the Northern Ireland Assembly received reports of a decline greater than 50%.[4]
Multiple possible causes of CCD have been identified. In 2007, some authorities attributed the problem to biotic factors such as Varroa mites and insect diseases (i.e., pathogens[5] including Nosema apis and Israel acute paralysis virus).[6][7] Other proposed causes include environmental change-related stresses,[8] malnutrition, pesticides (e.g.. neonicotinoids such as clothianidin and imidacloprid[9][10][11]), and migratory beekeeping. More speculative possibilities have included both cell phone radiation[12][13] and genetically modified (GM) crops with pest control characteristics.[14][15]
It has also been suggested that it may be due to a combination of many factors and that no single factor is the cause.[16][17][18] The most recent report (USDA - 2010) states that "based on an initial analysis of collected bee samples (CCD- and non-CCD affected), reports have noted the high number of viruses and other pathogens, pesticides, and parasites present in CCD colonies, and lower levels in non-CCD colonies. This work suggests that a combination of environmental stressors may set off a cascade of events and contribute to a colony where weakened worker bees are more susceptible to pests and pathogens."[19] Applying proteomics-based pathogen screening tools in 2010, researchers announced they had identified a co-infection of invertebrate iridescent virus type 6 (IIV-6) and the fungus Nosema ceranae in all CCD colonies sampled.[20][21] However, subsequent studies have questioned the methodology used in these proteomic experiments.[22][23]
