Which method is often used to control pest populations sustainably?

Biological control strategies are a sustainable method for managing pest populations because they utilize natural predators, parasites, or pathogens to suppress pest populations. This approach can effectively reduce the need for synthetic chemicals, which can be harmful to the environment and non-target species. By harnessing the natural balance within ecosystems, biological control promotes long-term pest management that works in harmony with nature.

For instance, introducing beneficial insects like ladybugs can help control aphid populations, or using nematodes to target soil-borne pests without disrupting other organisms in the ecosystem. This method not only reduces reliance on chemical controls but also fosters biodiversity and the resilience of agricultural systems. Such practices can lead to healthier crops and a more stable environment over time.
