The influence of sublethal doses of insecticides on the reproduction of glossina-pallidipes austen and glossina morsitans morsitans westwood (Diptera: Glossinidae)
(1992)
Insecticides utilised in the field to control tsetse flies often do not reach
their targets in sufficient quantities to kill them. The effects of such sublethal
doses on the reproduction of these flies is therefore ...
The physicochemical investigation of termiticidal components from the local trees, Juniperus procera and croton megalocarpus
(1995)
For many years various methods have been employed to control termite and prevent damage by termites on buildings, trees and other plants. Termiticides of various kinds have been used but there has been a general concern ...
The hydrological characteristics of the arid and semi-arid parts of Kenya
(1993)
The purpose of the study was to investigate the
hydrological characteristics of the arid and semi-arid
lands (ASAL) of Kenya with a view of establishing the water
resources potential of ephemeral streams in providing
...
Ecological studies on the tropical warehouse moth Ephestia Cautella (walker) (Lepidoptera : Pyralidae) and its predator mite Blattisocius Tarsalis (berlese) (Acari : Ascidae) in relation to effective warehouse integrated pest management programmes
(University of Nairobi, 1996)
The abundance and economic importance 01 the moth Ephestia
cautella (Walker) on maize grain was established through field
surveys in central storage depots and detailed evaluations
carried out in selected warehouses. ...
Numerical simulation of the influence of the large-scale Monsoon flow on the diurnal weather patterns over Kenya
(1992)
The influence of the large-scale monsoonal wind systems on the diurnal weather patterns
over Kenya was investigated in this study using a three-dimensional limited-area
model known as the Regional Atmospheric Modeling ...
The flood hazard in the lower reaches of the Sondu/Miriu river
(University of Nairobi, 1990)
This dissertation is on the flood hazard on the River Sondu
floodplain which is structurally continuous with the Kano Plains in
Kisumu District. The incidence of floods has become greater in the

A taxonomic, ecological and commercial potential study of the genus gracilaria (gracilariales, rhodophyta) of the Kenya coast
(University of Nairobi, 1993)
A study was carried out on the taxonomy, ecology and the yield as well as properties of the polysaccharides of the marine algal genus Gracilaria, which is
one of the genera of commercial importance worldwide. Eight species ...
Space-time characteristics of streamflow in Kenya
(1998)
The major objective of this study was to determine the homogeneous
hydrological divisions through space-time analysis of stream flow and to develop the
best forecasting and flood prediction regional model. The homogeneous ...
