  abstract = {{S}imultaneously with a control of breeding sites primarily for #{C}ulex quinquefasciatus$ and secondarily for anophelines with #{B}acillus sphaericus$ in the town of {M}aroua (120,000 inhabitants) in {N}orth {C}ameroon, a survey of anopheline populations and of transmission rates of malaria was performed. {M}onthly night catches in 8 districts of the town emphasized the relation between the biting rate by #{A}nopheles$ in the districts and two main factors. {O}ne factor was the distance of a district from the breeding sites, i.e., natural flooded areas along the periphery of the town or artificial breeding sites (ditches, puddles) filled with rain water during the rainy season and with water from the water network throughout the year. {T}he second factor was the density of the habitation that reduced dispersal of femal mosquitoes from the breeding sites and the risk for inhabitants to be injected because of scattered bites. {T}he treatment with #{B}. sphaericus$ was followed by a delay (2 months) in the beginning of the transmission period and a decrease in the incidence of malaria cases studied in a health facility of the town. {I}t thus seems to be possible to reduce malaria transmission by applying #{B}. sphaericus$ to the breeding sites, but this requires a good knowledge of the location and dynamics of breeding sites and an improved formulation of the pesticide.
