Question:
Vector for Plasmodium vivax is
Vector for Plasmodium vivax is
Show Hint
Female Anopheles mosquito is both the vector and definitive host of Plasmodium because sexual reproduction occurs inside the mosquito.
Updated On: Jun 12, 2026
- Periplaneta
- Musca
- Anopheles
- Culex
Show Solution
Verified By Collegedunia
The Correct Option is C
Solution and Explanation
Concept:
Malaria is a protozoan disease caused by species of Plasmodium.
The parasite requires two hosts to complete its life cycle:
• Human (intermediate host)
• Female Anopheles mosquito (definitive host and vector)
Step 1: Identify the causative organism. Plasmodium vivax is one of the important malaria-causing species in humans.
Step 2: Identify the transmitting agent. The infective sporozoites are injected into humans through the bite of infected female Anopheles mosquito.
Step 3: Eliminate other options.
• Periplaneta = Cockroach
• Musca = Housefly
• Culex = Vector of filariasis and some viral diseases None of these transmit Plasmodium vivax.
Step 4: Final conclusion. The vector is: \[ \boxed{\textit{Anopheles}} \] Hence option (C) is correct.
