Phytochemical evaluation of Elaeodendron buchananii stem Bark for microbial activities
(Maseno university, 2010)Public health is under serious threat due to wide array of emerging and re-emerging infections as a result of resistance of microorganisms to first line drugs. Despite the wide availability of clinically useful antifungal ... -
Phytochemical evaluation of Ocimum kilimandscharicum GUERKE, Gnidia subcordata MEISN AND Annona mucosa jacq leaves for secondary metabolites and their insecticidal activities against Sitophilus zeamais and Prostephanus truncatus.
(Maseno University, 2023)Global food security of which maize is a major component is threatened by food loss due to storage insect pests. Sitophilus zeamais and Prostephanus truncatus cause stored maize losses of 20% world wide and 45% in Africa. ... -
Phytochemical investigations of lonchocarpus eriocalyx (harms), alysicarpus ovalifolius (schumach) and erythrina abyssinica (dc) for antiplasmodial, larvicidal, mosquitocidal and antimicrobial activities
(Maseno University, 2016)Management of parasitic disease continues to be a burden and a major public health problem the world over today. Malaria is most lethal of the parasitic vector-borne diseases due to drug and vector resistance to the available ... -
Relationship between mites infestation levels in Kenyan tea to overhead volatile organic compounds and their variations with seasons, regions and selected agronomic practices
(Maseno University, 2016)Tea (Camellia sinensis) is a major cash crop in Kenya that suffers economic losses due to Brevipalpus phoenicis and Oligonychus coffeae infestations during droughts. Pesticides use on tea is prohibited and pests control ... -
