Which type of pest management can be characterized by the use of traps and barriers?

Mechanical pest management refers to the use of physical methods to control pests, which includes the use of traps and barriers. Traps can be designed to capture pests, thereby reducing their population in a targeted area. Barriers, such as screens or row covers, can prevent pests from reaching plants or other susceptible areas. This method is effective because it doesn't involve the application of pesticides or chemicals, making it environmentally friendly and safe for beneficial insects and non-target species.

In contrast, biological pest management focuses on using natural predators or parasites to control pest populations, often leveraging the ecosystem's natural balance. Cultural pest management involves altering farming practices to reduce pest issues, such as crop rotation or adjusting planting times. Chemical pest management, on the other hand, utilizes pesticides and similar chemical substances to kill or repel pests. Each of these methods serves a different purpose, but mechanical methods specifically rely on physical devices like traps and barriers to achieve pest control.
