(School of Biological Sciences, University of Nairobi, 1996)Tree hole breeding mosquitoes and other associating arthropods were collected from three adjacent forests in western Kenya to determine distribution and habitat preferences. Immature stages were collected from natural ... -
Residues of Chlorfenvinphos and 2,4-dichloroacetophenone in cow milk in Western Kenya
(School of Biological Sciences, University of Nairobi, 1995)A survey of the literature revealed that livestock production ranks second to cereals, provides employment and helps in alleviating poverty especially in the rural areas of Western Kenya; that a number of acaricides are ... -
Resistance of timber to termite attack and the efficacy of two botanicals and wood ash in their protection
(School of Biological Sciences, University of Nairobi, 1995)Different tree species have different susceptibility to termite attack. Ten tree species commonly used in Kenya as a source of timber were exposed to termites with a view to investigating their natural resistance to this ... -
Artificial regeneration and sustainable yield management of mangrove forests at Gazi bay, Kenya
(School of Biological Sciences, University of Nairobi, 1995)Mangrove forests in Kenya are estimated to cover about 50,000 - 60,000 ha. However non-sustainable utilization, over-exploitation of resources and conversion to other land uses principally for fish pond, salt pans, ... -
Characterisation of immune responses in vervet monkeys (Cercopithecus Aethiops) following vaccination with leishmania donovani antigen
(School of Biological Sciences, University of Nairobi, 1995)Visceral leishmaniasis is a severe systemic human disease which is always fatal if left untreated. The treatment is however expensive, painful and has unpleasant side effects as repeated courses or a change of drugs is ... -

(Department of Zoology, University of Nairobi, 1994)Studies on the malaria parasite transmission, identification of vector-related risk factors, and their relationships with the incidence of severe malaria in children aged 1 to 4 years were undertaken in the the rural and ... -
Evaluation of physiological and behavioural resistance to permethrin and its cross-resistance spectrum in anopheles mosquitoes from Western Kenya
(School of Biological Sciences, University of Nairobi, 1995)Anopheles gambiae sensu lato and Anopheles funestus were collected from villages with permethrin impregnated bednets or curtains (0.5gm/m2 ), villages with no intervention measures and from the Ahero Rice irrigation Scheme ... -
Geology and obsidian sources around Naivasha area, Kenya.
(School of Biological Sciences, University of Nairobi, 1994)The study examines in detail an area between Mount Longonot in the east tthrough Lake Naivasha Basin to Mount Eburru in the west. The result is a model of major occurrences of obsidian quarry sources that may have been ... -
Use of short tandem repeats to describe genetic variability in Anopheles Gambiae from three countries in Africa.
(Department of Zoology, University of Nairobi, 1996-01)Macrogeographic variation in An. gambiae was measured by analysing four polymorphic STR loci in four populations by electrophoresis on horizontal slab polyacrylamide gels. Mosquitoes were sampled from inland (Asembo) ... -
