What is the role of biological control in pest management?

The role of biological control in pest management involves encouraging natural predators to reduce pest populations. This approach utilizes the natural ecosystem's existing dynamics, where certain organisms have evolved to keep pest populations in check. By promoting or conserving the presence of these natural enemies—such as beneficial insects, birds, or other wildlife—landowners and farmers can enhance the natural regulation of pest species without solely relying on chemical pesticides.

This method is particularly valued because it can lead to sustainable pest management practices, reducing the risk of pesticide resistance and minimizing harmful impacts on non-target organisms and the environment. Integrating biological control into pest management strategies often leads to a balanced ecosystem, which is more resilient against pest outbreaks.

In contrast, other options focus on chemical methods, monitoring, or eradication strategies that might not support ecosystem balance or sustainability in the long term.
