Which mosquito is primarily responsible for the transmission of malaria?

Anopheles mosquitoes are primarily responsible for the transmission of malaria due to their specific feeding habits and breeding sites. They are the only mosquitoes that can harbor the Plasmodium parasites, which are the causative agents of malaria. These mosquitoes typically bite at night and are highly effective in transmitting the parasite during their blood meals, as the parasites enter the mosquito's salivary glands and are subsequently injected into the human host during feeding.

While other mosquito genera, such as Aedes and Culex, are known for transmitting other diseases like dengue and West Nile virus respectively, they do not play a role in the transmission of malaria. Mansonia mosquitoes mostly feed on plants and are not known to be significant vectors for malaria transmission as well. Therefore, Anopheles stands out as the definitive vector for malaria, confirming its vital role in the disease's life cycle and transmission.
