Studies on the behaviour of peridomestic and endophagic M form Anopheles gambiae from a rice growing area of Ghana.

  • Authors: Charlwood JD, Egyir-Yawson A, Pitts RJ, Salgueiro P, Tomás EV, Pinto J

The ‘paddy paradox’, the occurrence of large populations of vectors but low amounts of malaria transmission where irrigated rice is grown, was investigated in a village in Ghana where M form Anopheles gambiae are common.

Field, genetic, and modeling approaches show strong positive selection acting upon an insecticide resistance mutation in Anopheles gambiae s.s

  • Authors: Barbosa S, Donnelly MJ, Egyir-Yawson A, Hastings I, Lynd A, Mitchell S, Weetman D, Pinto J
  • Journal: Molecular Biology and Evolution

Alleles subject to strong, recent positive selection will be swept toward fixation together with contiguous sections of the genome. Whether the genomic signatures of such selection will be readily detectable in outbred wild populations is unclear. In this study, we employ haplotype diversity analysis to examine evidence for selective sweeps around knockdown resistance (kdr) mutations […]

Geographic population structure of the African malaria vector Anopheles gambiae suggests a role for the forest-savannah biome transition as a barrier to gene flow

  • Authors: Caccone A, Charlwood JD, Della Torre A, Donnelly MJ, Egyir-Yawson A, Elissa N, Gomes B, Moreno M, Santolamazza F, Simard F, Vicente JL, Weetman D
  • Journal: Evolutionary Applications
  • Link: http://www.ncbi.nlm.nih.gov/pubmed/24062800

The primary Afrotropical malaria mosquito vector Anopheles gambiae sensu stricto has a complex population structure. In west Africa, this species is split into two molecular forms and displays local and regional variation in chromosomal arrangements and behaviors.
