Julien Orain, French beekeeper displays dead bees found in or near hives, on his honey production site, on June 9, 2009 in Campbon, France.  Beekeepers and environmental groups have repeatedly accused the pesticides to be responsible for much of the excess mortality of bees and called for the withdrawal of recently approved products as Force 1.5 G or Cruiser. The study found the increased use of a pesticide like Force 1.5 or Cruuiser which is linked to causing serious harm in bees worldwide. Swiss agrochemicals company Syngenta has legally challenged in August 2013 a partial EU ban of one of its pesticides that has been shown to kill bees.
