PMRA is intensively reviewing neonicotinoids and risks associated with them. Certainly the PMRA also has some internal studies looking at the risks of neonics to honeybees. So in terms of risks to honeybee health, I think the PMRA is in a better position to answer that question, although within AAFC we are looking at relative residues of insecticides in hive products and in crops, and by simply looking at the levels present, we can also do a cursory evaluation of how available they are to bees in realistic field settings.
