I'm looking for any comments...or better yet, some observable trends...regarding whether captured swarms or hives that came from cut-outs tend to have more Varroa destructor compared with managed hives.
FYI, I have been carefully checking drone brood in cut-outs, looking for evidence of Varroa.
Wondering if high Varroa numbers are an inducement to swarm?
Also wondering if healthy, rapidly-expanding hives are related to Varroa-resistant conditions which in turn cause swarms/feral hives to have some lower/higher incidence of Varroa.
Looking forward to hearing your experiences, thanks,
