| [larvivorous capacity of barbus pobeguini and possibility of using this in the fight against anopheles gambiae s.l]. | permanent breeding sites for anopheles gambiae s.l. were found to occur in the urban area of ouagadougou and to have some importance in the maintenance of vector populations. in these breeding places barbus pobeguini was found widespread and larvivorous as indicated by the presence of remnants of a. gambiae in its stomach contents. the use of b. pobeguini would avoid the introduction of non-local larvivorous fishes. a series of trials carried out in laboratory conditions with b. pobeguini of dif ... | 1988 | 3271991 |
| [a longitudinal entomologic survey on the transmission of malaria in ouagadougou (burkina faso)]. | a longitudinal entomological malaria survey was carried out in five zones of the town of ouagadougou, burkina faso, and in three neighbouring villages. the main vector is anopheles gambiae s.l. with an. funestus having a role in some localities during the dry season. pyrethrum spray catches were carried out once or twice per month to determine variations in vector density. inoculation rates were estimated from the number of blood-fed vectors per man and from the sporozoite rates. larval sampling ... | 1986 | 3455529 |
| [dispersion of anopheles gambiae s.l. in an urban zone of ouagadougou (burkina faso)]. | dispersion of anopheles gambiae s.l. from larval breeding places was examined in the town of ougadougou, burkina faso. a suitable study area was chosen, characterized by high concentration of larval breeding places along a water reservoir. mosquito density per room was calculated from the results of pyrethrum spray catches carried out on a series of seven groups of collecting stations along a transect from 100 to 1050 m from the water reservoir area. high density and uniform distribution of hous ... | 1986 | 3455531 |
| [chromosomal study of anopheles gambiae and anopheles arabiensis in ouagadougou (burkina faso) and various neighboring villages]. | adult females of anopheles gambiae s.1. were collected by pyrethrum spray catch in ouagadougou (burkina faso, formerly upper volta) and in four neighbouring villages. the collections have been carried out mostly during the 1984 rainy season. monthly collections in some sampling sites allowed a preliminary longitudinal study. by analysis of nurse cell polytene chromosomes in adult females, an. gambiae s.str. and an. arabiensis were identified in the study area. both species showed polymorphisms f ... | 1986 | 3455532 |
| insecticide susceptibility levels of anopheles gambiae s.l. in the area of ouagadougou, burkina faso. | tests to evaluate the susceptibility level in anopheles gambiae s.1. from ouagadougou and two nearby villages have been carried out. anopheles gambiae s.1. larvae from ouagadougou showed complete susceptibility to organophosphates and carbamates, and adults showed low-level resistance to ddt. nine percent survival of adult an. gambiae s.1. to one-hour exposure of 4% ddt was observed in samples from zagtouli village while in those from koubri village, where dieldrin also was tested, resistance to ... | 1986 | 3455533 |
| laboratory and field efficacy of bacillus thuringiensis var. israelensis and bacillus sphaericus against anopheles gambiae s.l. and culex quinquefasciatus in ouagadougou, burkina faso. | two wettable powders (bactimos and vectobac) and one flowable concentrate (teknar) of bacillus thuringiensis var. israelensis (b.t.i.) and primary powders of bacillus sphaericus isolates 1593 and 2362 were evaluated (laboratory) against field-collected larvae of anopheles gambiae s.l. and culex quinquefasciatus in ouagadougou, burkina faso. bactimos, vectobac and a corn-cob b.t.i. formulation (abg-6138g) were field tested against cx. quinquefasciatus and an. gambiae s.l. the isolates of b. sphae ... | 1987 | 3504891 |
| studies on insecticide susceptibility of anopheles gambiae s.1. and culex quinquefasciatus in the area of ouagadougou, burkina faso (west africa). | tests to evaluate the susceptibility level in anopheles gambiae s.1. and culex quinquefasciatus from ouagadougou and two nearby villages have been carried out. anopheles gambiae s.1. larvae from ouagadougou showed complete susceptibility to organophosphates and carbamates, and adults showed low level resistance to ddt. nine percent survival of adult an. gambiae s.1. to one hour exposure of 4% ddt was observed in samples from zaghtouli village while in those from koubri village, where dieldrin al ... | 1986 | 3507503 |
| odor-mediated host preferences of west african mosquitoes, with particular reference to malaria vectors. | the role of odors in mosquito host preferences was studied in a village near ouagadougou, burkina faso. two odor-baited entry-traps were put beside one another and a choice of host odor-laden air was blown out of them. odors of a human and a calf (of similar mass) were drawn from two tents in which each was separately concealed. allowances were made for trap position, differences in human-subject attractiveness, co2 levels, and trap contamination with alternative host odors. choices for the huma ... | 1998 | 9452293 |
| experimental formulations of bacillus sphaericus and b. thuringiensis israelensis against culex quinquefasciatus and anopheles gambiae (diptera: culicidae) in burkina faso. | efficacies of locally produced, sustained release granular formulations of bacillus sphaericus (bs) strain 2362 and b. thuringiensis israelensis (bti) were compared with commercial liquid concentrates of the same bacteria in cesspits and rain-filled puddles in ouagadougou, burkina faso. duration of control was dependent on the product, the transient nature of some sites, and the target mosquito larvae. bs granules applied at the rate of 3.0 g/m2 (30 kg/ha) reduced culex quinquefasciatus say 99% ... | 1999 | 10071494 |
| diversity in anopheline larval habitats and adult composition during the dry and wet seasons in ouagadougou (burkina faso). | several cases of malaria are frequently recorded during the dry period in ouagadougou town (burkina faso). this has led to the design of a series of studies focusing on both parasitological and entomological investigations intended to provide relevant health data on the risk of local malaria transmission according to the way of urbanisation. | 2010 | 20298619 |
| field efficacy of a new mosaic long-lasting mosquito net (permanet 3.0) against pyrethroid-resistant malaria vectors: a multi centre study in western and central africa. | due to the spread of pyrethroid-resistance in malaria vectors in africa, new strategies and tools are urgently needed to better control malaria transmission. the aim of this study was to evaluate the performances of a new mosaic long-lasting insecticidal net (llin), i.e. permanet 3.0, against wild pyrethroid-resistant anopheles gambiae s.l. in west and central africa. | 2010 | 20423479 |
