Anopheles pharoensis is a relatively large Anopheles
mosquito, which is very abundant in the Nile delta. Its average
dispersion from its larval breeding grounds is considerable, around
6 km. Occasionally, by taking advantage of a North-West wind, it
has been documented as traveling in excess of 100 km, once as far
as 280 km, biting large numbers of military personnel in the middle
of the desert. It is a vector in Egypt and is also present in
tropical Africa where its role as a vector is very weak, almost
negligible, where other major vectors are present.
