Insecticides are Becoming MORE Toxic to Honey Bees

During the past 20 years, insecticides applied to U.S. agricultural landscapes have become significantly more toxic — over 120-fold in some Midwestern states — to honey bees when ingested, according to a team of researchers, who identified rising neonicotinoid seed treatments in corn and soy as the primary driver of this change. The study is the first to characterize the geographic patterns of insecticide toxicity to bees and reveal specific areas of the country where mitigation and conservation efforts could be focused. According to Christina Grozinger, Distinguished Professor of Entomology and director of the Center for Pollinator Research, Penn State, this toxicity has increased during the same period in which widespread decline in populations of pollinators and other insects have been documented.
