Abstract

Low doses of contaminants and toxins can stimulate pests feeding on contaminated tissues of host plants and enhance herbivore activity and plant damage. These effects are opposite to those of high toxic doses, have largely been missed so far, and could compromise crop production. Thus, they deserve further consideration and study.

Keywords: adaptive response; biological plasticity; dose-response relationship; hormetic effect; pest priming.
