The Anopheles gambiae complex consists of at least seven morphologically indistinguishable species of mosquitoes in the genus Anopheles. The complex was recognised in the 1960s and includes the most important vectors of malaria in sub-Saharan Africa, particularly of the most dangerous malaria parasite, Plasmodium falciparum. It is one of the most efficient malaria vectors known.


Discovery and elements

Anopheles gambiae Anopheles gambiae African malaria mosquito

The Anopheles gambiae complex or Anopheles gambiae sensu lato was recognized as a species complex only in the 1960s. As of 2011, the A. gambiae complex consisted of seven species:

  • Anopheles arabiensis
  • Anopheles bwambae
  • Anopheles melas
  • Anopheles merus
  • Anopheles quadriannulatus
  • Anopheles gambiae sensu stricto

  • Anopheles gambiae African malaria mosquito Anopheles gambiae Say

    The individual species of the complex are morphologically difficult to distinguish from each other, although it is possible for larvae and adult females. The species exhibit different behavioural traits. For example, Anopheles quadriannulatus is both a saltwater and mineralwater species. A. melas and A. merus are saltwater species, while the remainder are freshwater species. Anopheles quadriannulatus generally takes its blood meal from animals (zoophilic), whereas Anopheles gambiae sensu stricto generally feeds on humans, i.e. is considered anthropophilic. Identification to the individual species level using the molecular methods of Scott et al. (1993) can have important implications in subsequent control measures.

    Anopheles gambiae in the strict sense

    An. gambiae s.s. has been discovered to be currently in a state of diverging into two different species — the Mopti (M) and Savannah (S) strains — though as of 2007, the two strains are still considered to be a single species. The An. gambiae s.s. genome has been sequenced three times, once for the M strain, once for the S strain, and once for a hybrid strain. Currently, ~90 miRNA have been predicted in the literature (38 miRNA officially listed in miRBase) for An. gambiae s.s. based upon conserved sequences to miRNA found in Drosophila.

    The mechanism of species recognition appears to be sounds emitted by the wings and identified by Johnston's organ.

    Historical note

    Anopheles gambiae Species

    An. gambiense invaded northeastern Brazil in 1930, which led to a malaria epidemic in 1938/1939. The Brazilian government assisted by the Rockefeller Foundation in a programme spearheaded by Fred Soper eradicated these mosquitoes from this area. This effort was modeled on the earlier success in eradication of Aedes aegypti as part of the yellow fever control program. The exact species involved in this epidemic has been identified as An. arabiensis.
