Hi All, I'm experimenting with powdered sugar. I've read Fakhimzadeh's 2000 paper, Aliano and Ellis's 2005 papers, and searched the archives. But I'm not finding a paper that details the efficacy (in percent) of mite removal by brushing a cup (more than Fakhimzadeh used) of sugar over the top bars (Aliano put bees in a cage). A simple test--does anyone know of someone who's done it? If I had a few collapsing colonies to sacrifice, I'd do the counts myself, but (knock on wood) my bees are finally looking pretty good! Any references out there? Randy Oliver -- Visit www.honeybeeworld.com/bee-l for rules, FAQ and other info ---
