Controlling Malaria Vectors Targets Mosquitoes

Steps:

• Identify the malarial vector: Malaria is transmitted by Anopheles mosquitoes.
• Determine control methods: Vector control focuses on killing or repelling mosquitoes to break transmission.
• Evaluate options: Match choices to mosquito-specific interventions.
• Select best fit: Insecticide directly targets insects like mosquitoes.

Why C is correct:

• Insecticides are chemicals designed to kill insects, including malaria-carrying mosquitoes, as per WHO vector control guidelines.

Why the others are wrong:

• A. Antibiotics treat bacterial infections, not insect vectors.
• B. Antibodies are immune responses to pathogens, not vector control tools.
• D. Herbicides kill plants, irrelevant to mosquito populations.

Final answer: C
