| dynamics of malaria transmission near two permanent breeding sites in baringo district, kenya. | entomological and malario-metric measurements were made near two permanent breeding sites in baringo district, kenya in order to determine the prevalence and seasonality of malaria and the relative importance of two local anopheline mosquitoes as malaria vectors. the breeding sites studied were the perkerra irrigation scheme and the loboi swamp, whereas the mosquito species involved were anopheles gambiae giles (sensu lato) and anopheles funestus giles. malaria accounted for 54 per cent of annua ... | 1997 | 9183076 |
| population genetic structure of the african malaria mosquito anopheles funestus in kenya. | anopheles funestus giles is a major malaria vector in africa, but little is known about the genetic structure of natural populations. in this study, microsatellite markers were used to investigate the genetic structure of a. funestus populations from kenya. two populations from western kenya 80 km apart and two from coastal kenya 50 km apart were collected and examined for allelic variation at five trinucleotide microsatellite loci. we found a. funestus giles was the predominant species (> 98%) ... | 2003 | 14628948 |
| dry season ecology of anopheles gambiae complex mosquitoes at larval habitats in two traditionally semi-arid villages in baringo, kenya. | pre-adult stages of malaria vectors in semi-arid areas are confronted with highly variable and challenging climatic conditions. the objective of this study was to determine which larval habitat types are most productive in terms of larval densities in the dry and wet seasons within semi-arid environments, and how vector species productivity is partitioned over time. | 2011 | 21352608 |
| plasmodium falciparum transmission and aridity: a kenyan experience from the dry lands of baringo and its implications for anopheles arabiensis control. | abstract: background: the ecology of malaria vectors particularly in semi-arid areas of africa is poorly understood. accurate knowledge on this subject will boost current efforts to reduce the burden of malaria in sub-saharan africa. the objective of this study was to describe the dynamics of malaria transmission in two model semi-arid sites (kamarimar and tirion) in baringo in kenya. methods: adult mosquitoes were collected indoors by pyrethrum spray collections (psc) and outdoors by centers fo ... | 2011 | 21569546 |
| mosquito species abundance and diversity in malindi, kenya and their potential implication in pathogen transmission. | mosquitoes (diptera: culicidae) are important vectors of human disease-causing pathogens. mosquitoes are found both in rural and urban areas. deteriorating infrastructure, poor access to health, water and sanitation services, increasing population density, and widespread poverty contribute to conditions that modify the environment, which directly influences the risk of disease within the urban and peri-urban ecosystem. the objective of this study was to evaluate the mosquito vector abundance and ... | 2011 | 21626425 |
| a survey of the anopheles funestus (diptera: culicidae) group of mosquitoes from 10 sites in kenya with special emphasis on population genetic structure based on chromosomal inversion karyotypes. | we sampled anopheles funestus giles mosquitoes from 10 sites in kenya to determine (1) the different members of this group present at these sites and (2) the population genetic structure of these species based on chromosomal inversion karyotypes with particular reference to the role of the eastern arm of the great rift valley and geographical distance as barriers to gene flow. four members of this species group, namely an. funestus s.s., an. parensis, an. leesoni, and an. rivulorum, were found. ... | 2003 | 14596280 |
| the effects of climatic factors on the distribution and abundance of malaria vectors in kenya. | since 1988 malaria epidemics have occurred in multiple sites in western kenya highlands. climatic variability has been associated with some of the recent epidemics. we examined influences of climatic factors on the distribution and abundance of three malaria vector species, anopheles gambiae, anopheles arabiensis, and anopheles funestus in western kenya and in the great rift valley. mosquito samples were collected from the lowland and highland areas with various climatic conditions. the three ve ... | 2002 | 12495180 |
