Hi Herve', Thanks for the report. Until the Bee Culture magazine published an article on the Lusbys, I hadn't given any thought to the effects of comb on bee behavior. But after seeing the impact that small cell sized comb had on colony health, my perspective changed. Comb is much more than just a place for bees to hang out, store food and raise young. I wish I could read that book for myself. But unfortunately my tongue is stuck in English :>) Regards Dennis :::::::::::::::::::::::::::::::::::::::::::::::::::::::::::::::::::: -- Visit www.honeybeeworld.com/BEE-L for rules, FAQ and other info --- ::::::::::::::::::::::::::::::::::::::::::::::::::::::::::::::::::::
