ShaneJ...Perhaps Mango here, and Mango there are two different things? Ours are amazingly sweet orange flesh, and very marketable for humans. I have never seen the slightest behavior to indicate robbing. In fact quite the opposite. I may be proven wrong in the future, but I find once the mango start to drop, the foragers usually have bellies full of a bunch of other stuff, too. No robbing here that I have ever seen. Won't be the first time I am wrong though. Mango is one of my favorites here! Honey robbing on the other hand, is a whole different ball game. I see no harm in allowing the bees to eat the fallen fruit they actually helped to pollinate. No problems thus far. They are always very peaceful.
