Effects of Imidacloprid Treatment of Hemlocks on Aquatic Ecosystems: Is the Cure Worse than the Disease?

Duration

October 2016 - September 2019

Narrative

The invasive exotic insect, hemlock woolly adelgid (HWA), is decimating hemlock ecosystems and treatment with imidacloprid is frequently used to control this pest. Our study is assessing the risks and non-target impacts of imidacloprid treatments in riparian hemlock forests on water quality, benthic macroinvertebrates, and stream salamanders. Results could be used to reassess the HWA treatment programs in our study areas (NPS parks and Monongahela NF) as well as other lands that have HWA treatment programs.
