Untill this year I had a very healthy population of Osmia rufa. This season
about 10 percent of emerging bees were parasitized by Chaetodactylus osmiae.
I am afraid that, come next spring, the situation will be even worse. Does
anyone have more information on the importance of this mite, its life cycle
and possible control methods ?
 
Thanks for any suggestion,
