[Characterization of entomopathogenic Bacillus samples isolated in Senegal and study of their toxicity for malaria vectors].
A screening program developed in Senegal to isolate new strains of entomopathogenic Bacillus has led to the isolation of 194 strains of Bacillus thuringiensis and 9 strains of Bacillus sphaericus from various sites and insect samples. The characterization of these strains regarding their H serotype, their crystal composition and their toxicity against mosquitoes (Culex pipiens, Aedes aegypti and Anopheles stephensi) has led to the isolation of 27 mosquitocidal strains. As malaria is an important public health problem in Senegal, these strains were more completely characterized looking for their toxicity against the two major malaria vectors in Senegal: Anopheles gambiae and Anopheles arabiensis.
