Why is it not advisable to try to kill all insect pests in turf?

• A. To maintain predator-prey beneficial aspects.
• B. To prevent damage to turf-based plants.
• C. Because pests are beneficial in all seasons.
• D. Because it is illegal to kill all pests.

Answer: (A)

In turf ecosystems, pest suppression relies on natural enemies—the predators, parasitoids, and pathogens that keep insect populations in check. Trying to kill every insect pest eliminates these beneficial organisms and their control services. Without predators and parasitoids, pest populations can rebound, often more aggressively, leading to greater turf damage than if some pests were left and managed with targeted, threshold-based methods. That balance—preserving predator-prey dynamics—is what makes it unwise to attempt total eradication. Broadly killing all pests can also disrupt other beneficial roles insects play and isn’t necessary when you can use selective, integrated pest management to keep pest levels below economic thresholds.
