Answer: Female Aedes aegypti mosquito.
- A Anopheles mosquito, the malaria vector
- B Female Aedes aegypti mosquito
- C Culex mosquito, a vector for filariasis
- D Sandfly, a vector for leishmaniasis
Correct answer: B. Female Aedes aegypti mosquito
Explanation: Dengue fever is transmitted by the female Aedes aegypti mosquito (also Aedes albopictus). It bites during the day. Dengue is caused by the dengue virus (flavivirus, 4 serotypes). No specific treatment; supportive care.
The Plasmodium parasite needs both hosts: the female Anopheles mosquito injects sporozoites while biting (infecting the human liver and RBCs, causing the malaria fever cycle), then picks up gametocytes from an infected person's blood, completing the parasite's sexual stage inside the mosquito.
