Making use of plant varieties that are naturally resistant to insect feeding is an example of which type of pest management method?

Using plant varieties that are naturally resistant to insect feeding exemplifies genetic pest management. This approach focuses on the inherent traits of plants, which have been selectively bred or modified to enhance their resistance to pests. By utilizing these genetically resilient plants, pest pressure can be reduced without relying on chemical pesticides, leading to a more sustainable agricultural practice.

Genetic resistance is a crucial strategy in integrated pest management (IPM) because it reduces dependency on chemical interventions and promotes a healthier ecosystem. This method can significantly lower the economic and environmental costs associated with pest control while still protecting crop yield and quality.

In contrast, other pest management methods are classified differently. Biological methods involve the use of natural predators or parasites to control pest populations, cultural methods focus on agricultural practices that improve crop health and reduce pest attractants, and physical methods utilize barriers or traps to prevent pests from causing damage. Each of these methods serves its purpose, but relying on genetic resistance directly targets the pest's feeding habits through plant traits.
