I'd like to know how to distinguish african bees from european bees and, if its possible to know the percentage of africanization. I prefer to analyse their morfological characteristics than wing beat frequency or composition of C-G (DNA). I'm a student of Animal Science at Universidade de Sao Paulo (Brazil), and i'm not a member of Bee-L. Alexandre Pongracz Rossi e-mail [log in to unmask] or [log in to unmask] Thanks
