Abstract:

The effective control of malaria through larva source management requires the information on the breeding sites and the physicochemical parameters present in them. This study aims to establish the correlation between the presence of physicochemical parameters in breeding sites of Anopheles gambiae sensu lato and the larval development. Anopheles gambiae s.l. mosquito larvae were collected from September to November 2024 during the small rainy season and from March to July 2025 during the great rainy season in the six districts of Couffo department which were Aplahoué, Djakotomey, Dogbo, Klouékanmè, lalo and Toviklin districts. Then, the measurements of physicochemical parameters in breeding sites were done in laboratory using a spectrophotometer DR5000. The other methods employed were: Thermometric, Potentiometric and Electrical conductometric. The results showed that the breeding sites with higher physicochemical parameters such as: Hydrogen Potential, Conductivity, Total Hardness and Alkalinity conferred the development to Anopheles gambiae s.l. larvae. However, there was a negative correlation between some parameters such as Total Dissolve Solids and Salinity and Anopheles gambiae s.l larval development. Different ions such as ammonia, calcium, magnesium, iron and phosphate were present in Anopheles gambiae s.l. larval habitats and served as nutrient composition to the larvae. The breeding sites of Anopheles gambiae s.l. are influenced by many physicochemical parameters and there is a relationship between the presence of physicochemical parameters in Anopheles gambiae s.l breeding sites and the development of these mosquito larvae.
