There are YouTube videos of these Asian hornets destroying an itialian hive. Only takes 40-50 hornets to completely destroy an Italian hive numbering 20,000-30,000. The hornets, with their huge jaws, easily remove the heads of honeybees, then feast on the honeybee brood.
The local honey bees of Japan have evolved a strategy to eliminate the Asian hornet scout. The honeybees invite the hornet into the hive showing no resistance, then in a quick move the honeybees surround the Asian bee and ball the hornet killing the hornet with heat. The honey bees ball the hornet, just like balling an undesirable queen bee and the honey bees use their wing muscles to generate heat thus killing the Asian scout.
To my knowledge, this strategy is only known to the Japanese honey bee. The hornets are armor plated and impervious to honeybee stings, the only weak spot is heat generate by honey bees in a tight ball.
