Which of the following describes a mechanical pest management practice?

Using traps to capture pests is a clear example of a mechanical pest management practice. This method relies on physical devices to control or eliminate pest populations without the use of chemicals. Mechanical practices can include various types of traps, such as sticky traps, snap traps, or electric traps, that physically catch and hold pests. This method is effective for monitoring pest populations, reducing their numbers, and minimizing damage to crops or structures.

In contrast, crop rotation involves changing the types of crops planted in a specific area, which disrupts pest life cycles but does not involve a physical mechanism for pest management. Introducing natural predators is a biological control method that leverages ecological relationships to manage pest populations, while using chemical pesticides employs synthesized chemicals aimed at exterminating pests.
