Excerpt from "EPA’s Final Work Plan (FWP) for the registration review of imidacloprid" > During the public comment period, the Agency received over 12,000 comments. The majority of those comments were received as a result of a letter writing campaign organized by Natural Resources Defense Council (NRDC) voicing concern that imidacloprid presents unacceptable risks to pollinators. The Agency received similar comments, i.e., concern over the risk to pollinators, from private citizens, honey beekeeper interests represented by the National Honey Bee Advisory Board (NHBAB), and environmental advocacy groups like Beyond Pesticides, NRDC, and Sierra Club. Excerpts from the Office of Pesticide Programs Response to the Sierra Club: As OPP's Director, I appreciate the opportunity to address the issues you raise and respond to your request that EPA suspend use of nicotinyl insecticides. OPP has been actively involved in pollinator protection, and we share your concern that pesticides may have a role in Colony Collapse Disorder (CCD). For more than five years, EPA has required studies to evaluate sub-lethal effects of nicotinyl pesticides on bees as a requirement for registration. We have evaluated the potential for a variety of sub-lethal effects in these studies, such as behavioral effects and incidence of disease, that could cumulatively affect the functioning of hives. These studies and information available in the open literature to date do not demonstrate a link between these effects and severe adverse impacts to bees, such as the incidence of CCD, that you identify in your letter. Specifically, a survey of beekeepers conducted by the U.S. Department of Agriculture (USDA) shows no consistent link between the use of neonicotinics or pesticides in general on the frequency or location of bee colony losses attributed to CCD. Additionally, acute and chronic effects thus far demonstrated for most pesticides, including the neonicotinics, in both registrant submitted data and open literature, are not consistent with the sudden disappearance of bees that is considered diagnostic for CCD. While the current battery of guideline toxicity tests on pollinators focuses on adult forage bees initially, higher tier testing (field pollinator tests) examines potential effects on adult bees and their brood. In each tier of testing, however, sublethal behavioral effects are monitored. None of these tests thus far have provided any evidence of adult bees abandoning the hive and leaving no trace of their whereabouts, as has been observed with CCD. Our discussions with academic and government researchers studying this problem reaffirm that there is currently no evidence directly linking pesticides, including the neonicotinoid insecticides, to CCD or other serious impacts to colonies where they have become more susceptible to disease. http://www.regulations.gov/ Docket Detail EPA-HQ-OPP-2008-0844 *********************************************** The BEE-L mailing list is powered by L-Soft's renowned LISTSERV(R) list management software.
