2010 AGRO New Investigator Award

Co-Sponsored by Dow AgroSciences

2010 AGRO New InvestigatorDr. Kyong Sup Yoon is an insecticide toxicologist and a medical entomologist. He received his M.S. in 2001 and his Ph.D. in 2006, both from University of Massachusetts-Amherst. While pursing his master’s research, he successfully determined the inducible oxidative metabolism of abamectin as a principal resistance mechanism in Colorado Potato Beetle (CPB), Leptinotarsa decemlineata Say. Dr. Yoon developed the first in vitro rearing system for large-scale maintenance of human head lice Pediculus capitis under laboratory conditions while conducting Ph.D. research. This system has become an industry standard to test formulated peduculicides. His graduate work was recognized by AGRO in the student award programs at the 2001 and 2006 National ACS meetings.

After graduation, Dr. Yoon expanded his efforts in bed bug resistance to deltamethrin and determined that a population collected from New York City was 264-fold more resistant compared to an insecticide-susceptible population. In this study, he and his colleagues identified two point mutations in voltage-sensitive sodium channel α-subunit gene from the deltamethrin-resistant bed bugs. This work was published in Journal of Medical Entomology and authors received Editors Choice Award for the Best Article of 2008.

Dr. Yoon’s current research focuses on elucidation of the specific binding site of a pyrethroid insecticide on the mammalian G-protein beta subunit and the rat voltage-sensitive sodium channel α-subunit (SNS or Nav1.8). He is an adjunct assistant professor in the Department of Natural Resources and Conservation, University of Massachusetts-Amherst and laboratory manager under Dr. J Marshall Clark’s supervision. He has trained students who are new to the laboratory or who need to acquire specific research techniques for their research projects. He is also a lecturer/instructor for courses offered in Environmental Science Program.
