Neither are the "Beyond Pesticide" people.

(Beyond Pesticides, February 6, 2013) The U.S. Environmental Protection
> Agency (EPA) has proposed to register a new insecticide, sulfoxaflor, which
> the agency has classified as “very highly toxic” to honey bees.

> Last month, EPA opened the comment period for the proposed conditional
> registration of sulfoxaflor, a new active ingredient, whose mode of action
> is similar to that of neonicotinoid pesticides -it acts on the nicotinic
> acetylcholine receptor (nAChR) in insects. Even though it has not been
> classified as a neonicotinoid, it elicits similar neurological responses in
> honey bees
