Popis: Abstract Members of the Anopheles gambiae complex and Anopheles funestus group are significant vectors of the malaria parasite Plasmodium species in the Afro-tropical region of the world. Molecular identification and variation in the wing were studied among female An. Gambiae complex and An. funestus group, to investigate morphological variations in the wing of local vectors populations of adult female mosquitoes found in five different locations in Akure North Local Government Area of Ondo State (Oba—Ile, Igoba, Isinigbo, Ita—Ogbolu and Iju). The variations in the wing character were found in the 3rd main dark spot area (Pre-apical dark spot—character 8) on the coastal region (Vein region I) of Anopheles gambiae complex wing; with two types (A and B) of wings identified with An. gambiae complex in the study area. Molecular study shows that all the wing type A are Anopheles gambiae s.s., they represent 53.39% of the total An. gambiae complex in the study area. Some of the Anopheles gambiae s.s. (28.30%) and all An. arabiensis (18.30%) were found with wing type B. Among 750 individual Anopheles mosquito species identified using Polymerase Chain Reaction (PCR method), 433 samples representing 57.73% were An. gambiae s.s. while 97 (12.93%) samples were An. arabiensis. Anopheles leesoni was the only member of the An. funestus group identified in the study area. Anopheles leesoni mosquitoes identified in the study location were 182, representing 24.27% of the total Anopheles mosquito species identified using the molecular method. Anopheles gambiae s.s., An. arabiensis, and An. leesoni are only Anopheles mosquito species responsible for malaria transmission in the study area. Anopheles leesoni was the only member of the An. funestus group identified in the study area.
