Researchers Argue for Curbing Use of Neonicotinoid Insecticides

Writing in Proceedings of the National Academy of Sciences, researchers from North Carolina State University and Pennsylvania State University argued for curbing the use of neonicotinoid insecticides by discontinuing the practice of applying them preventively on crop seeds. Although the practice is widespread in the United States, at least one study has cast doubt on its efficacy. Furthermore, evidence shows that these pesticides spread through the environment to pollinators, predators, and other insects they are not intended to kill. These scientists say that using less neonicotinoid insecticide could help reduce cascading effects on the environment from insecticides whose risks have not been fully characterized.
