Definition of Biological Control

Biological control, when considered from the ecological view point as a phase of natural control, can be defined as “The action of parasites, predators or pathogens in maintaining another organism’s population density at a lower average than would occur in their absence”. (Paul DeBach, 1964).

This definition is more demographic and ecological in context, but it does not explain the mechanism of control or regulation. It is a factual type of definition in that Biological control can be measured experimentally but man’s activity or manipulation of natural enemies not implicit / exhibited. Hence, in more precise way as an applied control, Biological control can be defined as “The destruction or suppression of undesirable insects, other animals or plants by the introduction, encouragement or artificial increase of their natural enemies”.
