Title: Molecular identification and population dynamics of the major malaria vectors in a rainforest zone of Nigeria
Abstract:Adult female mosquito vectors were collected from three villages in a typical rain forest area of Nigeria where no information exists on the major malaria vectors associated with human malaria. Sampli...Adult female mosquito vectors were collected from three villages in a typical rain forest area of Nigeria where no information exists on the major malaria vectors associated with human malaria. Sampling was carried out between January 2004 and January 2005 using pyrethrum and Human landing catch (HLC) techniques. A total catch of 2010 mosquitoes was recorded out of which 1800 were morphologically identified as female Anopheline mosquitoes. Further identification of the Anopheline species using the morphological keys revealed that 1399 (77.7%) belonged to the Anopheles gambiae s.l. and 401 (22.3%) to Anopheles funestus. A PCR based test on the Anopheles gambiae group identified 636 (45.5%) as Anopheles gambiae s.s and 763 (54.5%) as Anopheles arabiensis respectively. The cocktail PCR-assay on the total Anopheles funestus group showed 307 (76.6%), to be Anopheles funestus s.s and 94 (23.4%) to be Anopheles leesoni. The total number of Anopheles gambiae collected across the 3 villages was significantly higher (PRead More
