Kakugo virus

Kakugo virus is a picorna-like virus most commonly found in the brains of worker bees. It is a subtype of the Deformed wing virus. The Kakugo (Japanese for 'ready to attack') virus, when resident in a bee's brain, can contribute to aggressive behaviors such as are preeminent during a bee's guard phase in their life cycle. Kakugo is the first virus to have been found to cause aggressive behavior, although because the virus was only recently discovered to have such effects, research into the matter is limited.
