Biological control or biocontrol is a method of controlling pests, whether pest animals such as insects and mites, weeds, or pathogens affecting animals or plants by using other organisms. [1] It relies on predation , parasitism , herbivory , or other natural mechanisms, but typically also involves an active human management role.
Biological pest control is a rapidly expanding field of agriculture, where natural agents, primarily parasitoids and predators are used to control a pest organism that has been causing economic harm to human interests. These methods can be as alternatives or supplements to conventional pest control methods such as insecticides.

Early methods included the use of sulphur compounds, before 2500 BC in Sumeria. In ancient China, insecticides derived from plants were in use by 1200 BC to treat seeds and to fumigate plants. Chinese agronomy recognised biological control by natural enemies of pests and the varying of planting time to reduce pests before the first century AD.
Many chemical compounds produced by plants protect them from pests; they are called antifeedants. These materials are biodegradable and renewable, which can be economical for practical use. Organic farming systems embraces this approach to pest control. [5] Biopesticides can be classified thusly:
Biological control (See Biological pest control) Control method involving a biological control agent that is a natural enemy of a target pest (Heutte and Bella 2003). Bioregion (See Ecoregion) A biological subdivision of the earth's surface delineated by the flora and fauna of the region (Allaby 1998). Biota
Non-pesticidal Management (NPM) describes various pest-control techniques which do not rely on pesticides. It is used in organic production of foodstuff, as well as in other situations in which the introduction of toxins is undesirable. Instead of the use of synthetic toxins, pest control is achieved by biological means.
