Which is the biological control of pests?

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 are the major techniques 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.

How does biological control reduce the use of pesticides?

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.

How can natural enemies help in pest management?

In agricultural systems, the most common natural enemies are other insects and spiders. Natural enemies can help keep plant-feeding insects from attaining damaging population levels.

What is biological control briefly explain biological control?

Biological control is a method of restricting effects of harmful animals, pathogens and plants using other useful organisms, e.g. microorganisms, insects and plants that inhibit the harmful organisms.

Who is best rodent pests biological control?

Bacillus thuringiensis, a soil-dwelling bacterium, is the most widely applied species of bacteria used for biological control, with at least four sub-species used against Lepidopteran (moth, butterfly), Coleopteran (beetle) and Dipteran (true fly) insect pests.

What is biological control of pests How is it beneficial?

Biological control is the beneficial action of parasites, pathogens, and predators in managing pests and their damage. Biocontrol provided by these living organisms, collectively called “natural enemies,” is especially important for reducing the numbers of pest insects and mites.

What is biological pest control and examples?

Often, the natural enemies are found in the home range of the invasive pest. Some notable examples of classical biological control include the use of decapitating flies (several Pseudacteon species) against red imported fire ants, and a group of flea beetles, thrips, and stem borers used against alligator weed.
