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

1. Physical

2. Cultural

3. Genetic

4. Biological

The correct answer is: Genetic

Utilizing plant varieties that display natural resistance to insect feeding is an illustration of genetic pest management methods. This approach capitalizes on the inherent traits of specific plant breeds that have been developed or selected due to their ability to withstand or deter pests. By employing these resistant varieties, growers can lessen their reliance on chemical pesticides, which not only helps in maintaining ecological balance but also mitigates potential negative impacts on non-target organisms. This method is grounded in the principles of genetics, where the desired traits are either naturally occurring or enhanced through selective breeding or biotechnological advancements. It reflects a proactive strategy in pest management that aims to prevent pest problems before they arise, rather than simply reacting to infestations. Hence, the focus on genetic resistance not only improves crop yields but also contributes to sustainable agricultural practices.
