Sulfoxaflor is from the sulfamine family and is also a systemic pesticide. Sulfoxaflor is effective against a wide range of sap-feeding insects and exerts its insecticidal activity as an agonist at the insect nicotinic acetylcholine receptor (nAChR), which plays a central role in the mediation of fast excitatory synaptic transmission in the insect central nervous system. Sulfoxaflor has not been evaluated previously by the Joint FAO/WHO Meeting on Pesticide Residues and was reviewed at the present Meeting at the request of the Codex Committee on Pesticide Residues. While it is not a neonicotinoid, it is systemic pesticide that targets the same neural receptors as the neonicotinoids. As we continue our special series called “The Neonicotinoid Viewâ€, hosts June Stoyer and special guest-host, Tom Theobald will be joined by Dr. Susan E. Kegley, to discuss the impact of sulfoxaflor and discuss the pros and cons of this agro-chemical. Dr. Kegley is Principal and Founder of the Pesticide Research Institute (PRI), an environmental consulting firm providing research, analysis, technical services and expert consulting on the chemistry and toxicology of pesticides. Dr. Kegley's consulting work focuses on pollutant fate and transport; human and ecological exposure assessment and risk assessment; development of tools to assess relative risks for different pesticides; development of integrated pest management (IPM) approaches to minimize pesticide use; environmental monitoring (with a focus on air and water sampling); and analytical chemistry. She also has expertise in pesticide regulation and policy, ecotoxicology, human toxicology, and epidemiology. Dr. Kegley has a BS in Chemistry, Summa cum laude, from the University of Richmond and a PhD in organic/inorganic Chemistry from the University of North Carolina at Chapel Hill.
