Which statement about biological control methods is true?

Modifying the environment to enhance natural enemies is a key principle in biological control methods. This approach focuses on creating an ecosystem that supports and promotes the natural predators or parasites of pest species. By enhancing the habitat for these beneficial organisms, it is possible to improve their effectiveness in controlling pest populations naturally. This strategy aligns with biological control’s objective of reducing reliance on synthetic pesticides while fostering a more balanced ecosystem.

The other statements misrepresent the concept of biological control. Biological control does not rely solely on pesticides; in fact, it aims to reduce the need for chemical interventions by utilizing natural mechanisms. Additionally, not all pests can be controlled through biological methods, as the success of these approaches depends on many factors, including the specific pest, the environment, and the availability of effective natural enemies. Lastly, monitoring is a crucial component of biological control, as it helps assess pest populations and the impact of natural enemies, ensuring that the control measures are effective and making it possible to adjust strategies as needed.
