Frankly from the standpoint of spreading disease and parasites, packages
and migratories are one and the same.  Granted packages are one way, but
where in the definition of  the word "migratory" is a return trip
implied?   While individual packages may be dispersed over a wider area,
unless they become part of a "migratory" outfit they rarely move again.
The same can't be said for "migratories" and if one factors in the number
of moves per year to different locations, not to mention the number of
other "migratories" and "sationaries" those hives come in contact with
over the course of a year, the picture changes.  Bellowing when your
"pet" ox is gored, splitting frog hairs and finger pointing is not only
counterproductive but it contributes nothing to the solution.
