AMUSAN1, Babatunde  e  OGBOGU1, Sylvestre. Surveillance of mosquito larvae (Diptera: Culicidae) in microhabitats of a University Campus in Southwestern Nigeria. Cuadernos de Investigación UNED [online]. 2020, vol.12, n.1, pp.75-83. ISSN 1659-4266.

Introduction: Mosquitoes, vectors of vital diseases, are among the most deadly animals in the world. Their faunistic composition and prevalence of these mosquitoes are dependent on the characteristics of larval habitats. Objective: To determine how habitats influence the composition, abundance and distribution of the mosquito larvae on Obafemi Awolowo University, Ile - Ife campus. Methods: We sampled larvae monthly between 07: 00 and 10:00 (August, 2017 - January, 2019) using a standard dipping method. The microhabitats included ground pools, discarded containers, drainage channels and tree holes in each of the study sites. Results: We identified seven species distributed in three genera: Anopheles spp. (Anopheles gambiae, Anopheles funestus). Aedes spp. (Aedes aegypti, Aedes albopictus); Culex sp (Culex pipiens, Culex quinquefasciatus, Culex poicilipe). Culex was the dominant and most abundant genus (48%). Larvae were significantly (p<0,05) more abundant in the dry season. The highest abundance of mosquitoes was recorded in Akintola Hall (50,1%) and drainage channels were the main microhabitat. Location suggests that these species have affinity for humans and their dwellings. Conclusion: We recommend elimination of breeding sites (un-kept drainage channels, leakages and discarded domestic containers).
