Harold asks:
In the letter he didn't mention how many hives he has and how many he
checked.

Hives I run as production I do not count nor do i monitor each hive in those
yards. I KNOW they do not tolerate varroa and am not interested in finding
survivors among those hives.

Hives i run for production which are being not treated I simply cull those
hives which I deem as not as varroa tolerant as I care to see.

I usually check 24 hives with drops and have checked as many as 120 at a
setting as I have made up 120 reusable sticky boards from 4X8 white panels.

>Also does he have out yards and how far apart are they from each
other.There could be a great difference in the counts from different places.

I keep production hives  in four counties in Missouri. ( Jackson, Lafayette,
Johnson and Pettis ) on a regular basis.  I am migratory so I move
production hives around. Both treated an untreated hives.

Test hives which provide information such as I posted are on permanent
locations in a certain areas. Close by my operation so I can monitor closely
at times. I like to put those on the road I travel regularly so I can drop
by often. Yards with bees I don't care to use as a drone source I keep the
farthermost from  from home.

Sincerely,
Bob Harrison
