An assessment of neonicotinoid exposure on USFWS high diversity grasslands in the Prairie Pothole Region


March 2016 - September 2019


Neonicotinoids are a class of neuro-active insecticides developed in the 1990s because of widespread pest resistance and environmental objections to organophosphorus insecticides. We intend to estimate rate of uptake, accumulation, persistence, and concentration of neonicotiniods in native prairie plants on US Fish and Wildlife Service remnant native and restored grasslands in the Prairie Pothole Region.
