Jerry and others:
 
I am not expert in wax moths but can relay that Bt works best on small
instars that are eating voraciously.  (In tent caterpillars, we recom-
mend delaying treatment during cool weather when caterpillars aren't
eating much.)  Also Bt must be alive.  Sometimes storage conditions
(en route or on site) aren't the best.  (Well, Bt used to have to be
alive, but now that I think of it, newer Bts can be only the crystal
that the Bt produces.) Anyway, you might check that angle.
 
UGuelph's Entomology list has a discussion going on genetically altered
food  crops with Bt genes incorporated.  Genetically altered bees with
their own personal supply of Bt??????
