biological control, the use of living organisms to control pests. A natural enemy such as a parasite, predator, or disease organism is introduced into the environment of a pest or, if already present, is encouraged to multiply and become more effective in reducing the number of pest organisms.

What is biological control explain?
Biological control is a component of an integrated pest management strategy. It is defined as the reduction of pest populations by natural enemies and typically involves an active human role. Natural enemies of insect pests, also known as biological control agents, include predators, parasitoids, and pathogens.
What is an example of a biological control?
An example of biological control is the release of parasitic wasps to control aphids. Aphids are a pest of plants and cause huge damage to plants as they remove nutrients from the plant. The parasitic wasp lays eggs in aphids, as shown in the movie. In this way the aphid population will decrease quickly.
What is a biological control and what is it used for?
Biological control is the use of living organisms to suppress pest populations, making them less damaging than they would otherwise be. Natural enemies of insects play an important role in limiting the densities of potential pests. These natural enemies include predators, parasitoids, and pathogens.
Why is biological control used?
Biological control is an alternative to using pesticides and involves using one species or biological agent to control the population size of another species. The organism used is called a biological control agent. By releasing a natural predator into the crop growing area, the number of pests can be reduced.
What is classical biological control?
Classical biological control (CBC) refers to the intentional introduction of an exotic biological control agent for permanent establishment and long-term pest control to an area that the pest has invaded.
What are the types of biological control?
There are three general approaches to biological control; importation, augmentation and conservation of natural enemies. Each of these techniques can be used either alone or in combination in a biological control program.
What are the 3 types of biological control agents?
Introduction. Biological control is the use of living organisms to maintain pest populations below damaging levels. Natural enemies of arthropods fall into three major categories: predators, parasitoids, and pathogens (Altieri et al., 2005; Mahr et al., 2008).
What is biological method?
The biological method refers to bioremediation, in which biological processes (microorganisms) are used to degrade and metabolize chemical substances and restore environment quality. It is a cheap, sustainable remediation method, and yet benign to the environment.
