The vector for the malaria parasite is the female Anopheles mosquito.
A vector is an organism that carries and transmits a disease from one host to another. In the case of malaria, the disease is caused by a parasite called Plasmodium and it is transmitted to humans through the bite of a female Anopheles mosquito. The female mosquito takes in the parasite when it bites an infected person and then passes it on to another person when it bites again. So, the female Anopheles mosquito acts as the vector for the malaria parasite, spreading the disease from person to person.
