I remember now--memory isn't the best anymore. In WA, they apparently discovered that honey bees have a natural defense to murder hornets. I guess the hornets are very sensitive to heat. The bees instinctively? or learned this. When the hive is attacked, they increase activity in the hive raising the temperature above what the hornet can tolerate and they die. Here's more on it. Murder hornets and thermal defense by honeybees
Correction: The Japanese honeybees have a natural defense; the European honeybees do not. That's really why people are freaking out about their appearance in the US. They worry they could destroy bee colonies.
