A chemical emitted by an organism of one species that influences the physiology or behavior of an organism of a different species. Synthetic allelochemicals are sometimes used as herbicides or insecticides.

absoluta were obtained in plants with high content of this allelochemical. In contrast, the highest values for plant, leaflet and leaf injuries were observed in plants with low acylsugar content.
The vegetal mass produced by the coverings must be considered (Table 2), which is responsible for the physical effect of weed suppression; this might be completed by a produced allelochemical, although this study has not focused in its determination.

Traits such as the physical properties of the leaves (thickness, hardness, texture, epicuticular wax, and surface hairiness), chemical properties (allelochemical), and nutritional properties influence the amount of leaf consumed by an insect (SMITH, 2005, HANLEY et al., 2007).
