Description

Introduction:Mosquitoes are major vectors responsible for many vector-borne diseases. They develop in various larval habitats. Understanding these breeding sites is essential for developing effective vector control strategies. This study aims to identify the types of breeding sites of Aedes mosquitoes in domestic environments in Benin.
Methods: Data were collected between August 2023 and November 2024. In each municipality, domestic and peri-domestic containers were inspected, and the results were recorded on a tablet. Larvae samples were collected from positive breeding sites. A chi-square test was performed to compare proportions using R software, version 3.6.3. STATA and QGIS software were used for statistical analysis.
Results: In the municipalities of Djougou, Bassila, Savalou, and Bohicon, larval habitats in the categories of domestic containers (indoors) and tyres (outdoors) were the most prevalent and infested with mosquito larvae. However, in the municipality of Parakou, tyres were the most prevalent. In the municipalities of Boukoumbé, Savè, Bantè, Dassa-Zounmé, Lokossa, Comé, and Grand-Popo, domestic containers were predominant both indoors and outdoors of human dwellings. Furthermore, Aedes aegypti was the most abundant species in all the inspected breeding sites. Culex quinquefasciatus, Aedes albopictus, Aedes vittatus, Anopheles gambiae, Culex nebulosus, and Culex tigripes followed, but were relatively low in proportion.
Conclusion: The study revealed an array of mosquito breeding sites, with tyres, buckets, jars, cans, cisterns, and barrels being the most prevalent. Each municipality has its own specific breeding sites. The presence of these types of breeding sites in domestic and peri-domestic environments provides an ideal breeding ground for mosquito larvae. These results clearly demonstrate the need for an integrated breeding site management system based on environmental factors, health education, and community engagement in each municipality.
