Those hornets would tear the killer bees up just as much. I read somewhere (can't vouche for accuracy) that the reason killer bees are called that is because they are more aggressive and their sting contains a pheromone that 'tells' the others where/what to sting. Almost like tagging a missile target with a laser. That wouldn't improve the bees chances at all.
Makes sense to me. I knew the killer bees were more aggro, but thought their sting was more powerful also. If their sting is equal to a regular honey bee, you're right, the results would be the same.
I just hope that no one is ever stupid enough to export those hornets Anywhere
My earlier comment about studying the hornet's VAAM substance, do the studies in Japan!
