What does biological control refer to in pest management?

Biological control in pest management specifically involves the use of natural predators, parasites, or pathogens to manage pest populations. This method leverages the natural ecosystem where certain organisms feed on or eliminate pests without relying on synthetic chemicals. By introducing or enhancing the population of these beneficial organisms, it is possible to achieve a sustainable and ecological balance, reducing the need for chemical interventions.

This approach is favored because it can lead to longer-term pest management solutions and minimizes environmental impact. It also helps in preserving biodiversity and can be a cost-effective method of pest control over time. In contrast, using synthetic chemicals targets pests directly, which can lead to resistance issues and environmental harm, while manual removal or environmental modification does not utilize natural biological relationships. Thus, understanding biological control is essential for effective and sustainable pest management practices.
