Anopheles (Cellia) sergentii species complex

Habitats

Anopheles sergentii is known as the ‘oasis vector’ or the ‘desert malaria vector’ due to its distribution within oases across the Saharan belt in northern Africa and into the Middle East, and its ability to cope with the extreme climates across this region. It may be able to survive in such harsh conditions due to its adaptability. It makes use of a range of larval habitats, including streams, seepages, canals, irrigation channels, springs, rice fields and most other non-polluted, shallow sites that contain fresh water with a slow current, slight shade and emergent vegetation or algae. However, larvae have also been found in moderately brackish habitats, areas of stagnant water, light to moderately polluted locations or in sites in full sunlight. In general, the presence of vegetation or algae seems to be the only characteristic common to all larval habitats of this species.

Resting and feeding preferences

Various studies have described An. sergentii as principally or even highly zoophilic. In villages where animals are housed in rooms within human habitations, An. sergentii may be diverted away from human hosts and towards animals. The exo-/endophilic and exo-/endophagic status of An. sergentii is unclear. Anopheles sergentii can overwinter as both adult females and larvae.

Vectorial capacity

Anopheles sergentii is considered to be a dominant malaria vector species.
