Agroterrorism, also known as agriterrorism and agricultural terrorism, is a malicious attempt to disrupt or destroy the agricultural industry and/or food supply system of a population through "the malicious use of plant or animal pathogens to cause devastating disease in the agricultural sectors". It is closely related to the concepts of biological warfare and entomological warfare, except carried out by non-state parties.
A hostile attack, towards an agricultural environment, including infrastructures and processes, in order to significantly damage national and international political interests.
The terms agroterrorism, along with agroterror and agrosecurity, were coined by veterinarian pathologist Corrie Brown and writer Esmond Choueke in September 1999 as a means to spread the importance of this topic. The first public use of agroterrorism was in a report by Dr. Brown which was then reprinted in a front page article of the New York Times on Sept. 22, 1999 by reporter Judith Miller. Dr. Brown's article in 2,000 for Emerging Diseases of Animals (American Society for Microbiology) made these words a permanent fixture, and they soon ended up as part of everyday use. The Oxford Dictionary now recognizes the word agroterroism and its derivatives. An initial debate by Dr. Brown and Mr. Choueke involved the spellings agriterror vs. agroterror. The spelling with the "o" won, as it was closest to bioterrorism and thus would be easier to remember.
Clemson University's Regulatory and Public Service Program listed "diseases vectored by insects" among bioterrorism scenarios considered "most likely". Because invasive species are already a problem worldwide one University of Nebraska entomologist considered it likely that the source of any sudden appearance of a new agricultural pest would be difficult, if not impossible, to determine. Lockwood considers insects a more effective means of transmitting biological agents for acts of bioterrorism than the actual agents. Insect vectors are easily gathered and their eggs easily transportable without detection. Isolating and delivering biological agents, on the other hand, is extremely challenging and hazardous.
