Integration of edible beans (Phaseolus vulgaris L.) into the push–pull technology developed for stemborer and Striga control in maize-based cropping systems
(Elsevier Ltd, 2009-11)
Smallholder farming systems in eastern Africa are characterized by cereal/edible legume intercrops in fields severely constrained by parasitic weed, Striga hermonthica, cereal stemborers and declining soil fertility. The ...
On-farm evaluation of the ‘push–pull’ technology for the control of stemborers and striga weed on maize in western Kenya
(Elsevier Inc., 2008-03)
The ‘push–pull’ technology is a novel pest management strategy developed for control of stemborers and striga weed, Striga hermonthica, in maize-based farming systems in eastern Africa, where maize is intercropped with ...
Evaluation of farmers' field days as a dissemination tool for push-pull technology in Western Kenya
(Elsevier Ltd, 2009-03)
Our earlier study on farmers' adoption of ‘Push-pull’ technology (PPT) for management of cereal stemborers and Striga weed showed that field days (FDs) could be effective in technology dissemination. Hence, in an effort ...
Constituents of the essential oil of blumea brevipes (oliv. & hiern) willd
(John Wiley & Sons, Ltd, 1994)
The composition of the essential oil of Blumea brevipes (Oliv. & Hiern) Willd. isolated by hydrodistillation was analysed by GC and GC-MS. Sixty-eight compounds constituting about 94% of the oil were identified. The main ...
The Structure and Synthesis of Barakol: a Novel Dioxaphenalene Derivative from Cassia siamea
(Royal Society of Chemistry, 1970)
Barakol, from the leaves of Cassia siamea, is shown to be a novel dioxaphenalene derivative. A synthesis from 3,5-dihydroxyphenylacetic acid is described.
A 4-Alkyl-substituted Analogue Of Guaiacol Shows Greater Repellency To Savannah Tsetse (Glossina spp.)
The responses of Glossina morsitans morsitans Westwood to guaiacol (2-methoxyphenol), a mild repellent constituent of bovid odors, and seven analogues comprising 2-methoxyfuran, 2,4-dimethylphenol, 2-methoxy-4-methylphenol ...
Traditional use of mosquito-repellent plants in western Kenya and their evaluation in semi-field experimental huts against Anopheles gambiae: ethnobotanical studies and application by thermal expulsion and direct burning
(Oxford University Press, 2002-06)
Ethnobotanical survey in 2 communities in western Kenya revealed that the most commonly known repellent plants were Ocimum americanum L. (64•1%), Lantana camara L. (17•9%), Tagetes minuta L. (11•3%) and Azadirachta indica ...
Combined control of Striga hermonthica and stemborers by maize–Desmodium spp. intercrops
The African witchweed (Striga spp.) and lepidopteran stemborers are two major biotic constraints to the efficient production of maize in sub-Saharan Africa. Previous studies had shown the value of intercropping maize with ...
Insights for the Management of Different Locust Species from New Findings on the Chemical Ecology of the Desert Locust
(Cambridge University Press, 2011-09-19)
Recent studies on the chemical ecology of the desert locust, Schistocerca gregaria, have unravelled a rich and complex system of pheromonal and other semiochemical-mediated communication in this insect. The key pheromones ...
Anti-protozoal and structure-activity relationships of chemical constituents of Acridocarpus chloropterus Oliver (Malpighiaceae) from Tanzania
(Universal Research Publications, 2013)
Chromatographic separation of Acridocarpus chloropterus extract led to the isolation and identification of five triterpenes: β-sitosterol (1), stigmasterol (2), friedelin (3), oleanolic acid (4), ursolic acid (5); and five ...
