(University of NairobiSchool of Biological and Physical Sciences, 1974)The effects of the eriophyid miteAceria ficus Cotte, the tetranychid miteTetranychus arabicus Attiah and castor-oil pollen on the development and fecundity of the phytoseiid predatorPhytoseius plumifer (C. & F.) were ... -
The “picnic” model for research training at African Universities: evaluation and preliminary comparison
(University of Nairobi.Department of Meteorology, 1998)What distinguishes the “Picnic” model for research training at African universities from more classical models is reviewed and it is shown how the “Picnic” model deals with remaining drawbacks from the now popular “Sandwich” ... -
Pigeonpea (Cajanus cajan) varietal response to insect podborer infestation in Kenya.
(University of Nairobi.Department of Zoology, 1980)In field trials with (a) determinate and (b) indeterminate pigeon pea cv., pod damage by Heliothis armigera, Pardasena virgulana and Melanagromyza obtusa and seed yield losses ranged from 37% and 23% in an early-flowering ... -

pinous Process Fixation Devices for Instrumented Spinal Fusion.
(2013-09)Lumbar spinal fusion is a well-established surgical procedure for many spinal conditions. Posterior instrumentation may be added to provide immediate stabilization and improve fusion rates. Spinous process fixation, a type ... -
Pitfalls in technology transfer: Kenya's construction industry
(University of NairobiSchool of Biological and Physical Sciences, 1994-10)Tremendous growth in technology adoption by developing countries is evidenced by the large number of hardware and software imports in engineering, medicine and telecommunications. Although each import carries with it both ... -
Plant derived larvicides as a tool to manage malaria in Kenya
(Department of Chemistry, University of Nairobi,Department of Zoology, University of Nairobi, 2003)Malaria remains a serious parasitic disease killing over one million people annually. One of the strategies to manage the malaria problem is to control the population of mosquito at larval or adult stages of their life ... -

Plant growth promotion induced by phosphate solubilizing endophytic pseudomonas isolates
(University of Nairobi, 2015)The use of plant growth promoting bacterial inoculants as live microbial biofertilisers provides a promising alternative to chemical fertilisers and pesticides. Inorganic phosphate solubilisation is one of the major ... -
Plant parasitic nematode assemblages associated with sweet potato in Kenya and their relationship with environmental variables
(University of Nairobi, 2016)Sweet potato is one of the most important staple food crops consumed in Kenya and throughout Africa but yields are greatly reduced by plant parasitic nematodes (PPN). The aim of this study was to determine the prevalence ... -

Plasmodium berghei ANKA: Selection of resistance to piperaquine and lumefantrine in a mouse model
(University of Nairobi, 2009)We have selected piperaquine (PQ) and lumefantrine (LM) resistant Plasmodium berghei ANKA parasite lines in mice by drug pressure. Effective doses that reduce parasitaemia by 90% (ED90) of PQ and LM against the parent line ... -
Plasmodium falciparum transmission and aridity: a Kenyan experience from the dry lands of Baringo and its implications for Anopheles arabiensis control
(School of Biological Sciences, 2011)Background: The ecology of malaria vectors particularly in semi-arid areas of Africa is poorly understood. Accurate knowledge on this subject will boost current efforts to reduce the burden of malaria in sub-Saharan ... -
Plasmodium-associated changes in human odor attract mosquitoes
(University of Nairobi, 2018)Malaria parasites (Plasmodium) can change the attractiveness of their vertebrate hosts to Anopheles vectors, leading to a greater number of vector–host contacts and increased transmission. Indeed, naturally Plasmodium-infected ... -
Plectranthus : A review of ethnobotanical uses
(School of Biological Sciences, 2006)Plectranthus is a large and widespread genus with a diversity of ethnobotanical uses. The genus is plagued with numerous nomenclatural disharmonies that make it difficult to collate accurate data on the uses. The aim of ... -
