According to research, it is less quality and quantity of pollen and yes I
would imaging quality of propolis collected, plus mites, plus bacteria the
cause.

According to researchers a combination of varroa, DWV and harmful bacteria
ALL need to be present for it to collapse a colony, and DWV and varroa
needed to show symptoms of DWV.

According to research that a varroa infestation can affect quality and
quantity of pollen foraged. So a long lived or division of labor in
itself may not provide adequate remedy if the bees are not getting the
quality and quality of nutrition they need to begin with.
>Just what is meant by presence doesn't cause colony death?
Just what I said, same as AFB can be present and not show clinical
symptoms. viruses can be present and not cause death or show symptoms.
Supporting this statement is research that found viruses present in “100%
of the queens tested“. In examination of 10 queens, researchers found
the viruses BQCV, CBPV, DWV, KBV, and SBV were present in one or more
queen tissues. The presence of DWV and BQCV was found in 100% of the
queens tested
