I must admit that I don't know if they do respond in the
same manner with smoke, however, they do respond in the
same manner as honeybees do when sprayed with sugar syrup.
I have several bumble bee hives as well as the honeybee
hives, and could attempt to determine if they do.  As all my
bumblebee hives are set up as observation hives once the
outer lid is opened, such observations are easy to determine.
Using one as a control, I could experiment on another to
determine the result.  Just let me know if you'd like me to run
the experiment.
