> I have several reports but there is no location data attached to them (for anonymity), other than the state (NY). What it looks like to me is that the varroa are under control but the DWV is through the roof. And yet, no DWV symptoms. PLB <
That is my experience as well. My workplace hives get tested as part of the USDA/Bee Informed survey and in August 2015 ( don't have 2016 results yet ) mite loads were at 1% but DWV was detected in 80% of the bees tested. If I recall correctly, some other test sites in the state had higher mite counts but less DWV detected in the samples.
