control of culex quinquefasciatus (diptera: culicidae) with bacillus sphaericus in maroua, cameroon.	two strategies were tested to control culex quinquefasciatus with bacillus sphaericus in maroua (population 130,000), cameroon. the treatment of all potential breeding sites (27,000) with b. sphaericus during the dry season caused up to a 90% reduction in the adult biting rate. because of the short persistence of b. sphaericus and the occurrence of new breeding sites, unacceptable levels of adult biting rates were reached again in 5 months. in the second strategy, two treatments per year of the ...	1997	9383769
impact of treatments with bacillus sphaericus on anopheles populations and the transmission of malaria in maroua, a large city in a savannah region of cameroon.	simultaneously with a control of breeding sites primarily for culex quinquefasciatus and secondarily for anophelines with bacillus sphaericus in the town of maroua (120,000 inhabitants) in north cameroon, a survey of anopheline populations and of transmission rates of malaria was performed. monthly night catches in 8 districts of the town emphasized the relation between the biting rate by anopheles in the districts and two main factors. one factor was the distance of a district from the breeding ...	1998	9599321
[malaria vector control in cameroon: past, present, future. reflections].	during the fifties, large scale malaria vector control projects based upon house spraying were implemented in southern and northern parts of cameroon in line of malaria eradication concept. in the south, the pilot zone of yaounde gathered about 150,000 inhabitants, in the forest area. first operations started in 1953 but the programme became actually operational in 1956. it was divided in two parts: the western part was treated with ddt, while the eastern one was treated with dieldrin. at the sa ...	2001	16579079
