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 ...
Management of witchweed, Striga hermonthica, and stemborers in sorghum, Sorghum bicolor, through intercropping with greenleaf desmodium, Desmodium intortum
(Routledge Taylor & Francis Group, 2007-02-27)
On-station and on-farm studies were conducted in western Kenya to assess the potential role of greenleaf desmodium, Desmodium intortum (Mill.) Urb., in a combined control strategy for witchweed, Striga hermonthica, and ...
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.
Sex differentiation studies relating to releaser aggregation pheromones of the desert locust, Schistocerca gregar
Behavioural responses of nymphs and adults in the gregarious phase of the desert locust, Schistocerca gregaria (Forskal) (Orthoptera: Acrididae) were investigated in a single-chamber bioassay system to a choice of two ...
Time-course haemolymph juvenile hormone titres in solitarious and gregarious adults of Schistocerca gregaria, and their relation to pheromone emission, CA volumetric changes and oocyte growth
The haemolymph JH III titres in solitarious and gregarious adult desert locusts, Schistocerca gregaria, were examined in relation to corpus allatum (CA) volumes, aggregation–maturation pheromone production in males and ...
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 ...
