Greetings,
if some U.S. beekeepers are no longer using Checkmite, then what are they
using to control varroa mites. Here in Quebec half of the beekeepers
immediately switched to Check Mite after heavy losses supposedly due to
Apistan failure. The beekeepers who do not wish to use Check Mite due to the
long term contamination are trying to perfect other techniques, such as
formic acid. Not many U.S. beekeepers mention tracheal mites? Has there been
a natural selection since the parasite appeared??
