What is the main vector for transmission of malaria?

The main vector for the transmission of malaria is the Anopheles mosquito. This particular genus of mosquito is specialized for breeding in specific water bodies and has a unique lifecycle that allows it to transmit the Plasmodium parasites, which are responsible for malaria. When an infected mosquito bites a human, it injects the parasites into the bloodstream, leading to infection.

Anopheles mosquitoes are the only vectors that can carry these parasites; their role in the lifecycle of malaria is crucial. The female Anopheles, which requires blood to develop its eggs, often bites humans and, in doing so, transfers the parasites from the host to another person.

The other options provided, such as houseflies, fleas, and ticks, do not play a role in the transmission of malaria. Houseflies are not blood feeders and therefore do not transmit this parasite; fleas are known for transmitting other diseases like the plague; and ticks are associated with diseases like Lyme disease rather than malaria. Thus, the Anopheles mosquito is uniquely linked to malaria transmission, making it the correct answer.
