Which statement about biological control methods is accurate?

Modifying the environment to enhance natural enemies is a key practice in biological control methods. This approach involves creating conditions that support the survival and effectiveness of natural predators or parasitoids that can help manage pest populations. By making environmental adjustments—such as planting specific vegetation, providing shelter, or managing habitats—pesticide applicators can promote the existing natural enemies of pests, which may reduce the need for chemical interventions and lead to a more sustainable pest management strategy.

In contrast, biological control does not involve importing pests, as the goal is to control pest populations through their natural enemies rather than introduce new threats. Additionally, while multiple pesticide use might be a strategy for conventional pest control, it is not a principle component of biological control, which relies more on promoting natural ecological balances. Likewise, biological control is fundamentally aimed at minimizing or eliminating the need for chemical interventions, so the focus is on natural methods of pest management rather than relying on chemicals.
