Call in to speak with the host
In the world of beekeeping, neonicotinoids have maintained the spotlight as the scientific evidence continues to grow regarding the decline of the world’s bee population. Neonicotinoids are defined by the EPA as a class of insecticides with a common mode of action that affects the central nervous system of insects, causing paralysis and death. All of the neonicotinoids were registered after 1984 and were not subject to reregistration. Some uncertainties have been identified since their initial registration regarding the potential environmental fate and effects of neonicotinoid pesticides, particularly as they relate to pollinators.
Data suggests that neonicotinic residues can accumulate in pollen and nectar of treated plants and may represent a potential exposure to pollinators. Adverse effects data as well as beekill incidents have also been reported, highlighting the potential direct and/or indirect effects of neonicotinic pesticides. Therefore, among other refinements to ecological risk assessment during registration review, the Agency will consider potential effects of the neonicotinoids to honeybees and other pollinating insects.
Dr. David Goulson, Professor of Biological Sciences at the University of Sterling and his team have conducted new research titled “Neonicotinoid pesticide reduces bumble bee colony growth and queen production.”
In this special series called “The Neonicotinoid View”, my co- host, Tom Theobald and I will be joined today by Dr. David Goulson, Professor of Biological Sciences at the University of Sterling to discuss his research. Stay tuned!
