First, hornets are not bees, they are a variety of wasp.
If a hornet colony loses its queen there will be no-one laying eggs, so the colony will eventually die out as the older workers are not being replaced.
The hornet, mice, other bees, wasps and small mites called varoa which can kill whole hives by making the queen infertile
No. Hornets are carnivores; they feed on other bees.
Queen bees only sting other queen bees.
WASPS AND OTHER bees and queen bees
Yes. This technique is used by Japanese honey bees on their predator the giant hornet. When the hornet enters a nest, the bees swarm over it and vibrate violently to produce heat. The heat they produce is about 2 degrees more than what the hornet can tolerate. They can only do this 1 hornet at a time and so far no other specie is known to do this yet.
other queen bees
If a queen bee dies, the whole colony will die out soon, because there will be no more production of royal jelly. Royal jelly are needed for potential new queen. Queen bees are the only bees that can produces new drones and workers bees.
