The Bee Problem :

Humans have been benefiting from bees for ages through honey, royal jelly or beeswax directly or indirectly through pollination. Bees are one of the most important pollinators. Out of 54 leading crops, 42% are pollinated by at least on wild bee species, while out of 107 leading crops about 33% are pollinated by honeybees and other wild pollinators (Klein et al., 2007). An estimate of 80% of flowering plants depends on pollination and about half of tropical plants are bee pollinated (FAO (1)).

Figure 1. Example of crops pollinated by bees (NAPPC)

The economic value of pollination of fruits vegetables and seeds is estimated to be close to $20 billion in the USA (FAO (2)), between $37 billion and $91 billion in the UK (BBC, Richard Black) and €153 billion worldwide (Gallai et al., 2008).

Honeybees have been more and more suffering from Colony Collapse disorder (CCD). CCD was first reported in 2006 and is defined as a colony only composed of the queen, substantial amount of food and young bees, without any adult bees or their dead bodies (USDA News and EPA article). CCD is the result of multiple factors including but not limited to pesticides, pathogens (Varroa mites, Nosema cerenae, deformed wing virus…), change or loss of habitat and poor nutrition (USDA News; EPA article; NRDC article). In 2006-07 and 2007-08 honeybee colony loss due to CCD in USA was estimated respectively to 31% and 36% which is higher than the 10-20% loss considered normal (UNEP report 2010).

Awareness needs to be raise regarding bees’ importance and the danger they face.

Our team want to raise awareness on bees’ importance for our ecosystem and the trouble they face, on one hand. On the other hand, in addition we want to establish a method to detect multiple factors related to CCD, indicating bees’ health state, which will allow early detection and early measures to save them.
