Clothianidin is a neonicotinoid insecticide that was developed jointly by Takeda Chemical Industries and Bayer. Neonicotinoids were developed to replace nicotine, which is an effective insecticide but degrades too rapidly to be practical for large-scale use. Neonicotinoids also replaced older pesticides that were harmful to humans and other mammals.
Recently, the use of neonicotinoids has been criticized because they are toxic to nontarget insects, especially honeybees. In 2013, the European Union (EU) issued a 2-year ban on clothianidin,听thiamexotham, and other neonicotinoids on crops that attract bees. But the US Environmental Protection Agency ruled that the data used by the EU were inconclusive, and it did not ban neonicotinoids.
Later in 2013, a study conducted by F. Pennacchio and co-workers at the University of Naples Federico II听: colony collapse disorder and deformed wing virus. This finding may lead to additional restrictions on the agricultural use of neonicotinoids.

Clothianidin and thiamethoxam were the Molecules of the Week for February 17, 2014听and October 15, 2012, respectively. Both are neonicotinoid insecticides that during the past decade have come under regulatory pressure because they are toxic to honeybees. Finally, this past week, the US Environmental Protection Agency canceled the registrations for 12 formulations that contain one or the other of these pesticides.

Clothianidin, imidacloprid, and thiamethoxam听were the Molecules of the Week for February 17, 2014, August 25, 2014, and October 15, 2012, respectively. All three are neonicotinoid pesticides, and all three have been found to contribute to the worldwide die-off of honeybees. Use of these pesticides has been gradually restricted during the past several years, but now the European Union is about to . Will the United States follow suit?
