The term “biological control” has been defined in many ways by various biologists. The earliest definitions of biological control focused on the use of predators and parasitoids (i.e., parasites of insects) to control another organism.

The “father” of modern biological control, Professor Harry Scott Smith, defined it as the use of natural enemies (whether introduced or otherwise manipulated) to control insect pests. Other well-respected biological control workers have provided their own definitions.

Dr. Paul DeBach refined the Smith’s definition and stated that biological control was "the action of parasites, predators, or pathogens in maintaining another organism's population density at a lower average than would occur in their absence." DeBach distinguished biological control from “natural control,” which he defined as "the maintenance of a more or less fluctuating population density of an organism within certain definable upper and lower limits over a period of time by the actions of abiotic and/or biotic environmental factors.”

Later, Dr. Robert van den Bosch referred to biological control as the "manipulation of natural enemies by man to control pests" and natural control as "control that occurs without man's intervention."

Biological control can be used to regulate numerous types of organisms including insects, mites, spiders, snails, weeds, trees, fungi, algae and even animal by-products (i.e., cattle dung). Natural enemies that control plants are actually highly specific plant feeders (i.e., herbivores). Even pathogens of organisms are used that cause fatal diseases (e.g., milky spore disease of the Japanese beetle).

Biological control is often referred to as “biocontrol” and among researchers in the field it is often shortened to “BC.” The major emphasis of W2185 scientists is the control of insect pests and weedy plants.
