HI Everyone, Peter wrote in part: "It would seem logical that if it possible to breed bees that are resistant to AFB then the same could be done for EFB; perhaps the mechanism is the same and AFB resistant bees would there be resistant to EFB?" Well, the answer is no the hygenic trait that is involved in resistance to AFB and chalkbrood does not confer resistance to EFB. We don't understand why but other mechanisms are involved with resistance to EFB. blane ****************************************** Blane White MN Dept of Agriculture [log in to unmask] :::::::::::::::::::::::::::::::::::::::::::::::::::::::::::::::::::: -- Visit www.honeybeeworld.com/BEE-L for rules, FAQ and other info --- ::::::::::::::::::::::::::::::::::::::::::::::::::::::::::::::::::::
