Scope for genetic enhancement of the parasitisation potential of four native strains of Trichogrammatoidea sp. nr. lutea Girault (Hymenoptera: Trichogrammatidae) in Kenya
(Taylor & Francis, 2007-09-14)In response to emerging interest in commercial mass production of Trichogramma for Helicoverpa armigera biocontrol in eastern Africa, laboratory experiments were undertaken to assess the scope for genetic enhancement of ... -
Smallholder summer flower production in Kenya: A myth or a prospect?
(XXVII International Horticultural Congress, 2008)“Summer flowers”, the general name given to annual species and bulbous perennials traditionally grown during summer in northern Europe, they include Ornithogalum saundersie (commercially known as “Arabicum”), Alstromeria ... -
Induced male-sterility alters dry matter distribution in solanum villosum mill.
(ISHS, 2008)African nightshades are leafy vegetables popular in Africa and South-East Asia for their high nutritional and medicinal value. The plants are strongly autogamic, exhibiting early and excessive flowering coupled with prolific ... -

Host-plant acceptance, fecundity and longevity of tetranychus evansi (acari: tetranychidae) on selected tomato accessions
(Afr. J. Hort. Sci., 2009)Seven tomato (Lycopersicon sp.) accessions were evaluated for their resistance to the tomato red spider mite, Tetranychus evansi Baker and Pritchard, in the laboratory. Data recorded was: (i) trichome density and (ii) ... -
Effect of pH and magnesium on colour development and anthocyanin accumulation in tuberose florets
(African Crop Science Conference Proceedings, Vol. 9. pp. 227 - 234, 2009)Anthocyanins are a group of plant pigments responsible for colors ranging from red to violet and blue. Anthocyanins are pigments that accumulate in the vacuoles of plant epidermal cells. Chroma and hue are dependent on ... -
Host-plant acceptance, fecundity and longevity of tetranychus evansi (acari: tetranychidae) on selected tomato accessions
(Global Science Books, 2009-01-21)Solanum villosum is an important leafy vegetable in Kenya whose production faces low yields. Two potentially high leaf-yielding genotypes of S. villosum, T-5 and an octoploid have been developed. Field experiments were ... -
Seasonality of food supply, coping strategies and child nutritional outcome in Sabatia-Kenya
(Airiti library, 2010)This study was conducted in Kenya. Samples of children and caregivers were selected using the EPI method. Food vendors and procurement strategy, demographic and socio-economic indicators of household were analyzed. A social ... -
Response of leaf yield and nutritive value of african nightshade (solanum villosum) genotypes to nitrogen application
(African Journal of Horticultural Science, 2010)The wild-type Solanumu villosum is an important leafy vegetable in Kenya, which however is low-yielding mainly due to the early flowering and prolific fruiting. Two new genotypes of S. villosum, T-5 and octoploid with ... -
Processed products of termites and lake flies: Improving entomophagy for food security within the Lake Victoria region
(ASSCAT, 2010-02)Among the factors contributing to food shortage in Africa are lack of appropriate preservation and storage facilities, tropical heat and poor road network for marketing produce. High food spoilage caused by high temperatures ... -
