>Are all of the surveyed indicating that collapsing or collapsed colonies
due to varroa do not get robbed?  That also sounds as rare and unusual as
the reports that CCD equipment is left alone by bees and pests.

Not at all!  In areas in which there is any nectar flow going on at the
time of collapse, colonies get robbed immediately.

>If true, then where do mite bombs come from?

Researchers are backing off on using that term.
In areas such as mine, I call the high-mite colonies "mite diffusers."
