Thanks to Fred Dunn that brought the following article to my attention:
Determination of the effect of electric fence system on productivity and behaviour of honeybees housed in different beehive types (Apis mellifera L.)

I need some help understanding how the fence could generate EMF if there was not a current flow produced by a short to ground.
In normal operations the fence is rarely activated except when the fence wires are intruded by a bear or other such creature. This
would be a rare occurance. How could such a rare event produce the results they describe?
On a related matter, bees don't seem to avoid household AC wiring when they swarm and create a colony under floor boards or in barns.
How can we reconcile this observation with the above experimental data if one assumes it is advantageous for bee colonies to avoid EMFs?
For me this is not an idle musing as I have sheep grazing near my hives and e-fences to keep them in graze zones.
