The life cycle of a female
anophele mosquito
Egg.
Larva.
Pupa.
Once an adult, anophele can fly.
Mating.
The female anophele looks for a blood meal
to ensure that her eggs develop.
She bites an individual who may be infected with malaria.
She ingests the blood containing the malaria parasite.
She lays her eggs in water.
The female anophele, now infected with the parasite,
has another blood meal and, as she bites, can transmit
the parasites to a healthy person

The female anophele, now infected with the parasite, bites
a healthy individual and thus transmits the malaria parasites.
The parasites migrate to the liver in less than an hour,
carried by the blood.
The parasites multiply in the liver cells for 7 to 10 days.
The infected liver cells release thousands of parasites
into the blood.
The parasites invade the red blood cells.
The parasites multiply in the red blood cells in 1, 2 or 3 days.
The red blood cells burst and release the parasites into
the blood. When enough red blood cells have burst,
the parasites provoke the symptoms of malaria. After a few
days, the sexed forms of the parasite, male and female,
appear in the blood.
PHASE 1 :
PHASE 2 :
development of the parasite
in the liver.
development of the parasite
in the blood.
A female anophele ingests the sexed forms
of the parasite during a blood meal.
The male and female parasites fertilise and produce
an egg, which crosses the stomach wall of the mosquito
and attaches to its outer surface.
The egg develops, the parasites multiply and produce
thousands of sexed forms of the parasite.
The parasites migrate and invade the mosquito’s salivary
glands. They can then be transmitted to man during
a blood meal.
