Which pest management strategy promotes biological control?

The strategy that promotes biological control is the introduction of natural predators of pests. This approach involves using living organisms that feed on or otherwise reduce pest populations, thereby helping to manage pest issues in a sustainable way. Biological control takes advantage of the natural predator-prey relationships found in ecosystems, allowing for the reduction of pests without relying solely on chemical treatments.

In contrast, using chemical pesticides exclusively often leads to resistance in pest populations and can harm non-target organisms, including beneficial insects. Encouraging pest reproduction to enhance their population is counterproductive; it does not address the problem of pest management and can lead to greater pest issues. Planting only monocultures can increase pest problems since it creates an environment that is more favorable for pests while reducing biodiversity that can provide natural pest control. Thus, introducing natural predators effectively leverages ecological balance to manage pest populations.
