>Microscopic examination for tracheal mites is most commonly done under a >dissecting scope. This is true but not absolutely necessary (high dollars $$$). A less power- ful (read 'less expensive') scope will do just fine (especially for the beginner). >Special media preperation is involved Not necessary for just the beginner or hobbiest. Remove head, remove collar and look inside, you'll find the mites if you've got 'em. It takes a little practice but the technique works fine once you figure it out. There is no need for elaborate prep work if you're not actually counting or recording the number of mites per bee or doing some other kind of "highly scientific" work. Now, who has some "cheap" scopes for sale??
