La conditioned prey aversion it consists of using chemical substances in the prey (or in an imitation of it) that produce an unpleasant adverse effect –such as vomiting, nausea and/or diarrhea– in the predator, so that it learns to reject this prey in subsequent encounters. It is about triggering a survival mechanism that many animals develop to avoid the consumption of toxic or spoiled food once they have had a first bad experience.
The diptych “Conditioned aversion to reduce predation by carnivores” is the IREC Disclosure Note No. 2, an informative material edited by the Institute for Research in Hunting Resources (IREC – CSIC, UCLM, JCCM) within the scope of the project “Application of innovative tools to reduce the damage caused by wolves in livestock in Castilla-La Mancha".
The diptych includes the description of conditioned aversion as a tool to control predation, the presentation of some fundamental results obtained in previous research on the operation of the tool and an outline of the lines of research that scientists have ahead of them, all This is contextualized in the conflict associated with the predation of large carnivores, such as wolves, on livestock.
