Malaria is transmitted by which mosquitoes?

• A. Aedes quadrimaculatus and crucians
• B. Anopheles quadrimaculatus and crucians
• C. Culex quinquefasciatus
• D. Mansonia species

Answer: (B)

Malaria is transmitted by mosquitoes of the Anopheles genus. The female Anopheles mosquitoes become vectors when they bite an infected person and ingest Plasmodium parasites; the parasites develop inside the mosquito and reach the salivary glands, ready to be transmitted in the next bite. Among common vectors listed, Anopheles quadrimaculatus and Anopheles crucians are the malaria-carrying species. Other genera like Aedes and Culex spread different diseases (yellow fever, dengue, West Nile, etc.), not malaria. So the pairing that reflects malaria transmission is the Anopheles species listed.
