There is an ambiguity here.  Are you referring to an LD50 for
individual bees. Does anybody do work on LD50s for colonies?  How do
the two relate?  It may be that LD10 for individual bees has about the
same effect as an LD50 for colonies.  Does anybody have any thoughts
on that?  I assume that work has been done somewhere...

Best,
Blair
