How so?

I ask as I see pesticide kills on a regular basis. I need to tell apart.

My guess is a CCD deadout mixed in with a few deadouts from a penncap M.
kill would fool most researchers. i have seen plenty of penncap M kills and
quite a few claimed CCD deadouts.

*Usually* the penncap M can not be detected in the deadout as the poison is
so deadly to bees the bees never return. All that's left is a queen and some
bees. If pollen is needed the hive empties and after awhile even nurse bees
forage. My point is the hive left is full of BROOD ,honey and pollen and
only a small number of bees and a strong hive can be reduced in an apple
orchard setting to look like a CCD deadout in a few hours *if* the bees are
active on the sprayed blooms.

One problem with pesticide kills is that they are not always the same even
when the same pesticide is involved. However is a severe case of bee kill
away from the hive the result would mimic CCD would it not?
If not in what way?
