Lionel,
There's no good way for humans to measure a single queen's pheromones in
the hive, but of course the bees are doing it all the time. The time and
expense involved are far greater than the cost of just replacing a
questionable queen.
How long have you been keeping bees in that location and how many
hives? Did your bees produce well there in years past?
Cheers,
