| laboratory tests of oviposition by the african malaria mosquito, anopheles gambiae, on dark soil as influenced by presence or absence of vegetation. | physical objects like vegetation can influence oviposition by mosquitoes on soil or water substrates. anopheles gambiae s. l. is generally thought to utilize puddles over bare soil as its prime larval habitat and to avoid standing water populated with vegetation. in kisian, kenya near kisumu, water often pools in grassy drainage areas both during and after periods of infrequent rains, when typical puddle habitats become scarce because of drying. this raised the question of whether an. gambiae ha ... | 2006 | 17038187 |
| anopheles gambiae: historical population decline associated with regional distribution of insecticide-treated bed nets in western nyanza province, kenya. | high coverage of insecticide-treated bed nets in asembo and low coverage in seme, two adjacent communities in western nyanza province, kenya; followed by expanded coverage of bed nets in seme, as the kenya national malaria programme rolled out; provided a natural experiment for quantification of changes in relative abundance of two primary malaria vectors in this holoendemic region. both belong to the anopheles gambiae sensu lato (s.l.) species complex, namely a. gambiae sensu stricto (s.s.) and ... | 2010 | 20187956 |
| abandoning small-scale fish farming in western kenya leads to higher malaria vector abundance. | fishponds become abandoned due to lack of access to both young fish and technical support and faster economic returns from other activities. certain conditions found in abandoned fishponds, such as absence of fish and presence of aquatic vegetation, are conducive to the presence of malaria vectors. we conducted a district-wide fishpond census to determine the maintenance status and mosquito populations of fishponds in kisii central district in western kenya. two hundred and sixty one fishponds w ... | 2008 | 18068136 |
| the development of plasmodium falciparum in experimentally infected anopheles gambiae (diptera: culicidae) under ambient microhabitat temperature in western kenya. | the effect of microhabitat temperature variation on the early development of plasmodium falciparum in experimentally infected anopheles gambiae s.s. (diptera: culicidae) was studied. batches of mosquitoes were fed artificially on gametocyteamic blood obtained from human volunteers and then held in five environmental conditions described as: (1) incubator maintained at constant temperature of 28 +/- 1 degrees c as control; (2) temperature unregulated laboratory environment; (3) screen house; (4) ... | 2004 | 15350861 |
| the incidence of mosquitoes feeding on mothers and babies at kisumu, kenya. | blood fed mosquitoes were collected inside four bed nets in which mother/child pairs, having different haptoglobin types, slept. the bloodmeals were analysed by gradient gel electrophoresis to determine on which person the mosquitoes had fed. the results suggest that the mothers are fed on much more than babies by both anopheles gambiae s.l. and culex fatigans. in one hut at least 15.2 per cent of the mosquitoes had taken all or part of their bloodmeal elsewhere. a greater number of double feeds ... | 1978 | 25970 |
| a study of the host selection patterns of the mosquitoes of the kisumu area of kenya. | the results of 12,168 precipitin tests on blood meals of mosquitoes of the kano plain caught by a variety of catching techniques indicate that to gain an accurate overall picture of feeding patterns both the indoor and the outdoor biotope must be sampled. cdc light traps operated inside houses and monkswood type light traps operated under the outside eaves of houses were found to collect larger numbers of blood fed specimens from a wider range of species than battery driven aspirators collecting ... | 1975 | 2997 |
