Peter, could you please elaborate on this observation?
Hostathion (an organophosphate) was banned, replaced at first by
pyrethroids, and then neonics. Bumblebees were then able to recolonize the
formerly toxic areas.
This seems like an improvement, ecologically speaking. What am I not
understanding?
