The Swarm (1978)

While investigating the bee-sting deaths of Air Force personnel at a missile base near Houston, Texas, an entomologist realizes that the dreaded African killer bees--long expected by scientists--have arrived in the United States. The hallucination-inducing bees derail a commuter train and destroy a nuclear power plant, killing hundreds of people as scientists race against the clock to develop an antitoxin to stop the devastation of The Swarm. From "master of disaster" Irwin Allen (The Poseidon Adventure, The Towering Inferno) and based on the novel by Arthur Herzog.
