How the use of just three of the neurotoxic neonicotinoids has spread across the American landscape since 1993

By courtesy of Tom Theobald, Boulder County Beekeepers, here are ‘animated’ maps constructed from USGS pesticide usage maps up until 2009, (now 4 years old). You can see how the use of clothianidin (given illegal conditional registration in 2003) has spread.

Each reveals, in a dramatic manner, how the use of just three of the neurotoxic chemicals has spread across the American landscape since 1993.

There are two other papers of interested. Eminent Canadian Toxicologist Dr Pierre Mineau was commissioned to write a Report for the American Bird Conservancy, showing that the issue is much wider than just Honey Bees. The Report shows massive declines in birds and aquatic invertebrates in the US. The effects of these insecticides: “should be considered, not on a farm scale, but in the context of whole watersheds and regions…many of those impacts may be mediated through the aquatic environment.”

In addition, Environment Canada has just put out a PowerPoint presentation from the National Water Research Institute to show that "clothianidin is the most persistent neonic residue and was present in wetlands in agricultural fields as a result of either snowmelt run-off or other transport mechanisms"
