THE MOSQUITO
There are three groups of mosquito that are a nuisance to man.
In the proboscis there are six slender lancets which are modified mouthparts used to pierce the skin and inject the anti-coagulant saliva. Disease organisms are then injected with the saliva.
How a Malaria Carrying Mosquito Works ...
As a female Anopheles mosquito with the parasite drinks her fill, she transmits many threadlike structures, call sporozoites, into the new host.

How a Malaria Carrying Mosquito Works ...
As a female Anopheles mosquito with the parasite drinks her fill, she transmits many threadlike structures, call sporozoites, into the new host.
- These sporozoites travel to the liver, where they multiple and form another kind of spore called a merozoite.
- The merozoites enter the bloodstream and penetrate the red blood cells, where they devour haemoglobin, the chemical that transports oxygen.
- When the blood cell disintegrates, the metozoites - now multiplied 16-fold - escape and infect other blood cells.
- A few merozoites form a sexual stage, which can be sucked up by another mosquito taking a meal.
- Two sexually active merozoites meet in the mosquito's gut and produce a new generation of parasites.
- This mosquito can transmit the infection only if she sucks more blood from an uninfected person before she dies.
