I haven’t got Africanized bees here in Vermont. Too far north for them to survive. They have been found in Maine and New York in migratory operations returning from their pollination runs. Also found in package bees or nucleus colonies originating in Florida or Texas, etc. not common. These have been found to be seriously defensive.
But s as bout if they can be calmed. I would say yes. I’ve seen a number of apiaries in Mexico where the bees are Africanized. The cells are the smallest I have ever seen...a good indication of the Scutellata genes. First time in an apiary there , they dressed me in a heavy suit. I’m thinking Ru-Row! Wasn’t long before I took off the suit. Too damn hot for that noise...they weren’t attacking me. Then in 2019 I visited 4 apiaries in the state of Oaxaca. Again they dressed me in a heavy jacket/veil setup. After nearing heat stroke...shaky and pukey, no more suit. My shite shirt...sleeves rolled up, and a veil. Plenty. Got a couple stings but no more. Funny thing...the stings are smaller than what I see here. Also much less venom per sting.
So, yes, I do believe they can be tamed
