Cartography of the lists of mosquitoes in the department of the littoral, a tool for fight against urban malaria in Benin

The study was carried out from January to December 2013 during the period of alternation between the long dry season and the small rainy season in the city of Cotonou, Southern Benin. The aim of the present study was to provide a mapping of breeding sites that highlights the boroughs of Cotonou with strong development of Anopheles, Culex and other mosquitoes. For this purpose, breeding sites were identified in each borough during both dry and rainy seasons. Then, the geographical coordinates of each site were noted. Mosquito larvae were collected and their density evaluated. A total of 997 breeding sites were enumerated. The most prolific areas in both rainy and dry seasons were identified: 1st, 6th, 12th and 13th borough. In these boroughs, a multitude of breeding sites were found throughout the year. This situation is probably due to the lack of adequate road network, predominance of flood areas, inadequate and poorly managed sanitation and uncontrolled territorial occupation.
