18-Year Study Links Neonicotinoids to Bee Colony Decline

A type of insecticide used on oilseed rape plants in the U.K. is likely to blame for worrying declines in bee populations across the pond.

Over the past few decades, bee populations around the world over have declined precipitously. Habitat loss, viruses and pesticides are fingered as culprits, but a recent 18-year study in England focuses the blame largely on neonicotinoids, a type of insecticide approved there in 2002 for agricultural use. The researchers monitored 62 species of bees be
