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

Utilizing plant varieties that exhibit natural resistance to insect feeding is an example of a genetic pest management method. This approach focuses on leveraging the inherent genetic traits of certain plants that make them less susceptible or completely resistant to specific pests. By selecting or developing these resistant varieties, pest management can be more sustainable and environmentally friendly, reducing the reliance on chemical pesticides.

A genetic method not only helps to protect crops from pest damage effectively but also contributes to maintaining the ecological balance by limiting chemical inputs. The ability of these plants to repel or endure pest attacks can lead to healthier crops, improved yields, and a lower likelihood of pest outbreaks.

In contrast, physical methods involve barriers and traps, cultural methods encompass agricultural practices that promote pest resistance through crop rotation and proper sanitation, and mechanical methods rely on physical actions like handpicking pests or using machinery. Each of these alternatives plays a role in pest management, but employing genetically resistant plant varieties specifically addresses pest resistance through biological traits.
