Excellent point, Bill!  That's why the title of the paper did not mention
imidicloprid.

However, although the Pettis paper states, "Two similar studies have just
been published that
directly treated individual bees with imidacloprid, fipronil,
or thiacloprid and then challenged them with Nosema with
similar synergistic interaction between Nosema and pesticide
exposure," in fact, in the Vidau study exposure to fipronil *decreased* nosema
spore proliferation, so not really similar.  So until tested, we don't know
which pesticides will increase nosema reproduction, and which suppress.
