> Nowadays, [tracheal] mite is very rarely mentioned. Why? Because the queen breeders have selected for tracheal mite resistance, and this seems to be a trait that nearly everyone can keep in their lines reliably. I'll still sample some bees, and thereby check each batch of queens, but if I found tracheal mite susceptibility, I'd have a quiet talk with the guy who sold me those queens. Tracheal mite resistance is right up there with 4 wings, two antenna, and 6 legs. Basic requirements. *********************************************** The BEE-L mailing list is powered by L-Soft's renowned LISTSERV(R) list management software.
