What are the biological control practices for insect pest?
A number of other biological approaches to the management of insect pests have at times been considered to be biological control tactics, and these include host plant resistance, transgenic insecticidal crops, insect growth regulators (IGRs), botanical insecticides, pheromone disruption techniques, and sterile insect …
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 some 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.
How are pests controlled by biological means?
There are three primary methods of using biological control in the field: 1) conservation of existing natural enemies, 2) introducing new natural enemies and establishing a permanent population (called “classical biological control”), and 3) mass rearing and periodic release, either on a seasonal basis or inundatively.
How many strategies are used for biological control of insects?
three
There are three basic biological pest control strategies: importation (classical biological control), augmentation and conservation.
How 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 a biological control method?
Biological control (biocontrol) involves the reduction of pest populations through the use of natural enemies such as parasitoids, predators, pathogens, antagonists, or competitors to suppress pest populations. Biological control is a practical option for suppressing pest populations because: it is easy and safe to use.
What is biological pest control in agriculture?
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.
Why biological control is important?
Advantages of biological control are that no artificial substances are added, and that pathogens / animals that develop resistance against biological control agents are rare. Biological control is an important component of integrated pest management,(Integrated Pest Management).
How does biological control of pests reduce pollution?
How does biocontrol method control insects?
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 and give an example?
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 aphids will die when the eggs come out and the young wasps start to grow. In this way the aphid population will decrease quickly.
