Which option best represents a genetic pest management approach?

• A. Biological
• B. Mechanical
• C. Cultural
• D. Genetic

Answer: (D)

Genetic pest management relies on altering the inheritance or genetics of pests to reduce their numbers or damage. This approach uses inherited traits to suppress populations rather than killing pests with chemicals, using natural enemies, or changing farming practices. A classic example is the sterile insect technique: releasing large numbers of sterile males so that matings produce no viable offspring, leading to a gradual decline in the pest population over generations. This directly targets the pest’s genetics to prevent reproduction. Biological control, by contrast, uses predators, parasites, or pathogens to reduce pests, not their genes. Mechanical methods rely on physical devices or barriers, and cultural methods involve changing farming practices to deter pests.
