Which pest management method uses selection to a pest as a means of managing pests?

• A. Cultural Resistance
• B. Mechanical Resistance
• C. Host plant Resistance.
• D. Biological Resistance

Answer: (C)

Using host plant resistance means relying on plant genetics to make the crop less suitable for pests. By choosing or breeding varieties with traits that deter feeding, slow pest development, or tolerate damage, you create selective pressure on the pest population. Only pests able to overcome these plant defenses will thrive, so overall pest success and crop injury are reduced even without heavy chemical use. This approach is preventive and fits into integrated pest management as a way to lower pest pressure over time. Other methods focus on changing practices, using physical barriers, or employing natural enemies, rather than leveraging the plant’s genetics to select against the pest.
