The war against the potato beetle was a campaign launched in Warsaw Pact countries during the Cold War to eradicate the Colorado potato beetle (Leptinotarsa decemlineata). It was also a propaganda operation that alleged it was introduced into East Germany, the People's Republic of Poland and Communist Czechoslovakia by the United States as a form of entomological warfare. Communist propaganda of the time claimed that the insect was being dropped from parachutes and balloons, with the intent of immiserating the populations of these countries, causing famines, and facilitating an economic crisis.[1]
