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.
Risk assessment usually includes four issues: 1) characterization of biological control agents, 2) health risks, 3) environmental risks and 4) efficacy. [23] Mistaken identification of a pest may result in ineffective actions.
Human disturbance of ecology ecological systems, particularly the development of monoculture and the movement of species tends to stimulate pest problems by reducing biodiversity which usually has natural controls that keep pest populations in line. Biological pest control does not seek to eradicate pests, but to keep them to economically ...
By the 1960s, problems of resistance to chemicals and damage to the environment began to emerge, and biological control had a renaissance. Chemical pest control is still the predominant type of pest control today, although a renewed interest in traditional and biological pest control developed towards the end of the 20th century and continues ...
For example, biopesticides help control downy mildew diseases. Their benefits include: a 0-day pre-harvest interval (see: maximum residue limit ), success under moderate to severe disease pressure, and the ability to use as a tank mix or in a rotational program with other fungicides.
Like most invasive plants, once garlic mustard is introduced into a new location, it persists and spreads into undisturbed plant communities. In many areas of its introduction in Eastern North America, it has become the dominant under-story species in woodland and flood plain environments, where eradication is difficult.
A decades-old cosmetic procedure called mesotherapy, which involves injecting unregulated mixtures of vitamins and drugs under the skin to reduce under-eye bags, is regaining popularity in the US.
Ladybirds (also known as lady bugs in North America) are a beneficial insect commonly sold for biological control of aphids. Beneficial insects (sometimes called beneficial bugs ) are any of a number of species of insects that perform valued services like pollination and pest control.
