Biological control is the use of non-chemical and environmentally friendly methods of controlling insect pests and diseases by the action of natural control agents. Unlike chemical method, which kills non target species, cause detrimental health effects to human beings and pollute environment.
What is biological control of pests and diseases?
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 4 biological methods of controlling pests?
Biological control of potential pest insects can be increased by: 1) conservation of existing natural enemies, 2) introducing new natural enemies and establishing a permanent population, and 3) mass rearing and periodic release of natural enemies, either on a seasonal basis or inundatively.
What are examples of biological control?
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.
What does biological pest control involve?
Biological pest control does involve human action and is often achieved through the use of beneficial insects that are natural enemies of the pest. Biological control is not the natural control of pests by their natural enemies; host plant resistance; or the judicious use of pesticides.
What is biological control of diseases?
Biological control is the control of disease by the application of biological agents to a host animal or plant that prevents the development of disease by a pathogen. With regard to plant diseases the biocontrol agents are usually bacterial or fungal strains isolated from the endosphere or rhizosphere.
What is biological method of disease control?
Biological control or biocontrol is a method of controlling pests such as insects, mites, weeds and plant diseases using other organisms. It relies on predation, parasitism, herbivory, or other natural mechanisms, but typically also involves an active human management role.
What is a biological control method?
What is biological disease control?
Abstract. Biological control is the control of disease by the application of biological agents to a host animal or plant that prevents the development of disease by a pathogen. With regard to plant diseases the biocontrol agents are usually bacterial or fungal strains isolated from the endosphere or rhizosphere.
Which insect is used for biological control?
Aphid mummies and a parasitic wasp (Lysiphlebus testaceipes). Biological control is the beneficial action of parasites, pathogens, and predators in managing pests and their damage….Predators.

What are the biological control methods for pests and pathogens?
There are three basic biological pest control strategies: importation (classical biological control), augmentation and conservation.
- Importation.
- Augmentation.
- Conservation.
- Predators.
- Parasitoids.
- Pathogens.
- Competitors.
- Combined use of parasitoids and pathogens.
What is biological control of plants?
The term biological control is used not only to control diseases in plants but also to control weeds and insects. Biological control was originally defined “the action of parasites, predators, or pathogens in maintaining another organism’s population density at a lower average than would occur in their absence”.
What are the three types of biological control?
Three forms of biological control are generally recognized: • Manipulative or Conservation Biological Control • Classical or Inoculative Biological Control • Augmentative Biological Control Here is how they apply in pepper and tomato production in Florida.
Who coined the term biological control?
The term biological control as a feasible preposition of plant disease management was coined for the first time by C. F. Von in 1914. Since then various bio- control products have been found to be very effective in controlling the plant disease.
What is habitat management to enhance biological control?
• Habitat management to enhance biological control refers to the establishment of environmental conditions amenable to natural enemies that increase and sustain their populations and improve their effectiveness in controlling pests.
