02mar12:00 pm1:00 pmISTC Sustainability Seminar Series - Are Pyrethroid Insecticides a Threat to Aquatic Non-Target Species?

Event Details

Presented by Michael Lydy, Ph.D. — Professor in the Departments of Zoology and Chemistry & Biochemistry, Southern Illinois University at Carbondale

Pyrethroid insecticides are currently used for pest control in terrestrial environments in both agricultural and urban areas world-wide, but often their residues are transported to aquatic systems through runoff events. These insecticides are hydrophobic so they tend to associate with the organic carbon portion of sediments and mortality has been linked with sediment pyrethroid residues. Special concern has been raised about the impacts of pyrethroid exposure in urban environments.  This presentation will address how prevalent pyrethroids are in the aquatic environment, and whether they are detected at high enough concentrations to cause harm to non-target aquatic species. It will also detail results concerning the potential for transfer of pyrethroids from resistant individuals to higher trophic level organisms.


This webinar will be broadcast live and also archived on ISTC’s website,, for later viewing. If you cannot attend the event at ISTC, you may view the webinar live by registering here.  ISTC is a part of the Prairie Research Institute at the University of Illinois Urbana-Champaign.
