C hemical ecology deals with molecularly mediated biological interactions. Its scope includes the production and chemical characterization of signal molecules, their emission and transmission mechanisms, their detection in recipient organisms, the transduction of these signals, and the neuroendocrine-mediated behavioral or developmental responses they evoke. Inevitably, given the breadth of its...
The roles and chemistry of pheromones that mediate reproductive behaviors of cerambycid beetles have received remarkably little attention, given the economic importance of many cerambycid species. Until recently, very few volatile sex pheromones and nonvolatile contact pheromones had been identified. However, that situation is changing rapidly, with the number of identified pheromones more than...
A llelopathy is defined by most scientists as the adverse effect of one plant species on another through production of phytotoxins (allelochemicals), although more expansive definitions have been formulated. Allelopathy is but one component of plant/plant interference, the other being competition for resources such as nutrients, light, and water. Allelopathy has been a recognized phenomenon for...
