>>I didn't find that Buckfast bees...Texas strain...was very resistant to Chalk. Forgive my bias but I won't order a queen from Texas, or some of the other southern states, due to the presence of AHB there. Especially, since this queen is needed for a nature center that gets many visitors. >>I wouldn't use either of these stocks, but would buy a hygienic Carniolan strain. Can you recommend a source? Has anyone used NWCs from Strachan and found them to clean up chalkbrood? >>Or perhaps a Russian queen from Francois Petit in Ontario, Canada. They are selected for being hygienic. You can find him at: http://www.igs.net/~pilgrimventures/The_Russian_Bee_Breeding_Program.h tm I'll check them out. I'll also check with Purvis Brothers about their bees' ability to clean up chalkbrood. Waldemar -- Visit www.honeybeeworld.com/bee-l for rules, FAQ and other info ---
