Dr. Niranjana Krishnan, an assistant research professor in biological sciences at Missouri S&T, says that certain insecticides are better than others for minimally impacting animal habitats. Krishnan recently published her research on milkweed plant habitats near corn and soybean fields in the journal Environmental Toxicology and Chemistry.
Krishnan’s paper, which was based on her doctoral dissertation research, was selected for the journal’s Best Paper Award for 2020 from 250 published papers. In the article, she reviewed the toxicity of six insecticides commonly used in leaf and seed treatments in Iowa and how they impact nearby monarch butterfly larvae.
