biological control

The natural control of one species by another, as is the use of biological pesticides.

biological control

a method of pest control using natural predators (harmless to other organisms) to regulate the size of pest populations. The technique has been mainly used against arthropod pests causing economic or medical problems. For example, red spider mites (Tetranychus urticae), which are pests of glasshouse crops such as cucumbers, are routinely controlled by application of commercially available samples of predatory mites (Phytoseilus persimilis) that feed on the red spider mites, thus reducing their numbers below an economically harmful level.
