BETWEEN MALE AND FEMALE MOSQUITO WHICH ONE CAUSES MALARIA?
Human malaria is carried out by certain species of mosquito of the Anopheles genus. They are the only females species of mosquitoes that can transmit malaria.
Both the Male and female mosquitoes feeds on various sources of sugar such as nectar. In addition to the sugar source female anopheles mosquitoes require iron and other nutrients for the developments of their eggs. As a result she bites the human to obtain the blood. The male does not need these proteins hence they do not transfer malaria.
Through the bite, a female anopheles mosquito transmits malaria. This often happens if they have been infected through a previous blood meal taken (If its host was infected).
It is true that the female anopheles mosquitoes are the only species of mosquito that can transmit human malaria.
Birds and other reptiles can also get Plasmodium, though different species than those that infect humans and other mammals, and these kinds of malaria can also be transmitted by other kinds of mosquitoes, such as Aedes and Culex mosquito.
Aedes and Ochlerotatus mosquitoes are painful and persistent biters. They search for a blood meal early in the morning, at dusk (crepuscular feeders) and into the evening. Some are diurnal (daytime biters) especially on cloudy days and in shaded areas. They usually do not enter dwellings, and they prefer to bite mammals like humans. Aedes and Ochlerotatus mosquitoes are strong fliers and are known to fly many miles from their larval developments sites.
Culiseta mosquitoes are moderately aggressive biters, attacking in the evening hours or in the shade during the day.
Culex mosquitoes are painful and persistent biters, they prefer to attack at dusk and after dark. They readily enter dwellings for blood meals.This type of mosquitoes are generally weak fliers and do not move far from home, although they have been known to fly up to two miles, they usually live only a few weeks during the warm summer months. Those females that emerge in late summer search for sheltered areas where they "hibernate" until spring. Warm weather brings them out again in search of water on which to lay their eggs. Culex mosquitoes usually lay their eggs at night over a period of time sticking them together to form a raft of from 100 to 300 eggs. A raft of eggs looks like a speck of soot floating on the water and is about 1/4 inch long and 1/8 inch wide. A female mosquito may lay a raft of eggs every third night during its life span.

I Stand to Fight Malaria is a sensitization program raising awareness about malaria and measures that can be taken to eradicate this mosquito borne parasite.
