Re: Penn State "COMB" project posts Dec 2019 update
Noting that Roland is older than dirt if he remembers beekeeping from before 1914.
Beekeepers exploited swarms to the maximum back then often doubling or tripling colony counts in a good year. This was the time period when swarm control methods were developed with Demaree and others publishing methods to prevent or manage swarming.
I wonder if Walt Wright's comb management methods would have helped? I expect they could have benefited from obtaining queens that were known to have mite resistance instead of starting with commercial queens that definitely do not.
A colony that swarms repeatedly and excessively will have low mite counts. Prevent that colony from swarming and you will usually get a very high mite count by fall.
