Malaria is a disease that is caused by parasites transmitted to humans from the vector called as infected female Anopheles mosquitoes.
It is caused by certain species of mosquitoes of the Anopheles genus and only females these species can transmit malaria.
Malaria is caused by a one-celled parasite called a Plasmodium. Female Anopheles is considered as vector (vehicle) that can transmit parasites of Plasmodium and causes malaria. When female Anopheles mosquitoes bites an infected person, then plasmodium is taken up into body of mosquito and reaches the salivary glands of mosquito. This saliva then is injected to prevent blood clotting of person, when the mosquito feed or bite on the blood of a person.
Only female mosquito need blood to lay their eggs. After the mating, female searches for blood because blood is the good source of protein for her eggs. Therefore, to nurture eggs only female anopheles require eggs and thus causes malaria.
