The mass breeding and release of sterile, incompatible specimens into pest populations is termed__________________?
Show answer Hide answer
Answer: A. Genetic control
Explanation
Genetic control involves mass-rearing and releasing sterile or genetically modified pests to reduce wild reproduction. Sterile males mate with wild females, producing no offspring and driving down the pest population over time. This species-specific method suppresses pest numbers successfully without introducing harmful chemical residues into nature. The sterile insect technique uses gamma radiation to sterilize mass-reared male pests safely before release. This environmentally friendly approach requires releasing millions of sterile insects to overwhelm wild populations. Successful genetic control programs have eradicated major agricultural and livestock pests from large regions.
Governments use genetic control programs to eradicate devastating livestock pests like the New World screwworm. Modern biotechnology expands genetic control options through inherited sterility and gene drive technologies. Integrating sterile insect releases into pest management protects sensitive ecosystems from chemical pollution. Option B is incorrect because chemical control relies on synthetic pesticides rather than releasing sterile insects. Option C is incorrect because regularity control is not a recognized technical term in pest management. Option D is incorrect because physical control involves temperature manipulation or barriers instead of genetics.
