Potato Fact #73

The Kartoffelkäfer-Abwehrdienst (Potato Beetle Defence Service) was established during WWII to research the potential weaponization of the Colorado potato beetle. In Oct. 1943, researchers painted 40,000 beetles and airdropped them over fields near Speyer. The results were inconclusive. To date, there are no known cases of the beetle being deployed in “entomological warfare.”
