Subject: varron on drone brood
A similar observation...when using drone brood as a trap crop, often,
not always, the mite load on the trap frame as a whole will be more or
less evenly distributed across the frame (this is early in the season
when the load is heavier), whereas, small clusters of drone brood on a
damaged frame, as Allen says, in a different part of the colony will
be...extremely heavily infested, or clean or nearly so. The
consistency of this made me curious, and an anecdotal observation is
that those clusters heavily infested were further from the center of
the brood (cooler?) than those clusters closer...by at least a frame,
often two. By the third round of this in a colony (after 60 some days)
this went away, but if any varroa remained, they were in the clusters
farthest from the center (which by now may be those locations that at
one time were closer), which by now had moved...again, anecdotal on
not many 8 frame colonies, in northeast Ohio.
