EPA Describes New Registration as Safer for Bees
On January 21, 2015, the U.S. Environmental Protection Agency (EPA) announced that it is registering a new insecticide, flupyradifurone, which EPA claims is “safer for bees” and will be “an alternative to more toxic products including pyrethroid, neonicotinoid, organophosphate and avermectin insecticides.” EPA has been under increasing pressure to take action to mitigate a decline in the viability of honeybee colonies known as colony collapse disorder or CCD. The neonicotinoid class of insecticides has been a subject of particular regulatory scrutiny, based on assertions that pesticides in this group are particularly toxic to pollinators. EPA has been reluctant to single out pesticide use as the dominant cause of CCD, and has suggested that habitat loss, infections with the varoa mite, and exposure to other pathogens are likely to be contributing factors as well.
In early 2013, the European Food Safety Authority released a risk assessment indicating that three neonicotinoids, clothianidin, imidacloprid, and thiamethoxam, pose an acute risk to pollinators, which led subsequently to a two-year suspension of the registrations for these three neonicotinoids in the European Union. Later that year, EPA informed registrants that it would require new labeling for neonicotinoids to mitigate risks to pollinators. In June 2014, President Obama issued a memorandum creating a federal task force to promote the health of honeybees and other pollinators, and directed EPA to assess the effects of pesticides, “including neonicotinoids,” on pollinator health.
Neonicotinoids have become more popular in large measure because of restrictions on organophosphate use that were intended to protect applicators and to reduce potential dietary risks from treated commodities. Although EPA has not expressly determined its view regarding how much neonicotinoids are contributing to CCD, EPA has been under pressure to take decisive action to address the risk to pollinators. By characterizing a newly registered insecticide primarily in terms of the risk that it poses to bees, EPA appears to be suggesting that alternatives to the neonicotinoids will become an important part of the regulatory response to CCD.
