Distribution of dominant or potentially important malaria vectors<br />
A wide range of primary vectors exists globally. They are usually the target of most control efforts.<br />

The two most important methods of vector<br />
control are ITNs and IRS. ITNs are particularly<br />
effective against mosquitoes that bite late at<br />
night while people are sleeping under the treated<br />
net and IRS is effective against mosquitoes that<br />
bite and rest indoors. ITNs and IRS are much<br />
less effective against species that bite and rest<br />
outdoors such as the forest vector An. Dirus,<br />
which is widespread in Southern Asia. For<br />
these vectors, alternative strategies such as<br />
insecticide-treated hammocks and the use of<br />
personal repellents are sometimes employed.<br />
Some species with readily identified and accessible<br />
breeding sites, such as the urban vector<br />
in India An. stephensii, can be controlled using<br />
larvicidal technologies (spraying of larvicides or<br />
deploying fish which eat Anopheles larvae). Thus,<br />

vector control for settings outside of Africa must<br />
be carefully chosen to suit the circumstances<br />
prevalent in a country.<br />
Because there is much variation in the behaviour<br />
of vectors that carry malaria, and because<br />
P. falciparum and P. vivax have different<br />
characteristics, the epidemiology of malaria<br />
is highly variable across the world. This report<br />
examines the epidemiology of malaria, and<br />
progress of malaria control, in four geographical<br />
regions outside of Africa. The four regions<br />
illustrate the diversity of situations in which<br />
malaria is encountered and the challenges<br />
for control but it is acknowledged that the<br />
epidemiology of malaria is still highly variable<br />
within these regions.<br />
