338RE: [beemonitoring] Disease spread vector
- Jun 25, 2008I don't think 'clean new' honey bees really exist. There would be
some new disease some populations of honey bees wouldn't have,
but the usual suspects are fairly endemic. Ponds and flowers are probably
places bees can pick up diseases (maybe/ maybe-not mites), but the accepted
thought that I understand is that robbing of dead honey bee colonies
is the primary method 'not so infested' bees get very infested with
mites and logically thinking, other diseases as well.
And then of course there is the normal population build up of
mites and nosema you get through the seasons from the mites and nosema
that inevitably came with the new bees.

Trying to learn:
An issue of sharing a pond bank with possibly diseased neighbor's
bees, and "clean new" bees of the pond owner...
Are these mites more prevalent in nurses on brood?
These become foragers, yes? Do mite infestations in foragers
exist at near-same levels as nurses? ... indicating a reasonable
(reasonably high/negative) risk when sharing banks of a small pond?
Or is the risk equal as the vector is the visited flower, anyway?
Or do bees not visit "previously-owned' flowers?
(I thought I had read that. they tended not to.)
