Population dynamics of pine woolly aphid, Pineus pini (Gmelin) (Hemiptera: Adelgidae), in Kenya
(Kenya Agriculture Research Institute,Department of Zoology, University of Nairobi, Nairobi, KenyaCentre for Overseas Pest Research, College House, Wrights Lane, London, UK, 1980)The population dynamics of Pineus pini (Gmel.) was examined in two locations in the Kenya Highlands where the mean annual precipitation ranges from 620 to 1400 mm. Variations in population densities were related to rainfall. ... -
Population dynamics of predacious phytoseiid mites, Euseius kenyae and coffee thrips, Diarthrothrips coffeae and their Interactions in coffee agro ecosystems in Kenya.
(School of Biological Sciences, 2012)Several strategies are employed in management of insect pests. Among these, chemical control is a priority to most farming communities where pest incidences occur while other existing options such as biological control are ... -
Population Modeling: Sustainable optimal harvesting in Fish Farming
(University of Nairobi.School of Mathematics, 2000)We develop a matrix model for a harvesting policy that maximizes the harvest of a population without altering its age structure. The model is subsequently applied in harvesting a fish, Tilapia, Oreochromis niloticus ... -
Population of predacious phytoseiid mites, Euseius kenyae (Swirski and Ragusa) on coffee treated with different soil applied fertilizers
(African Journal of Agricultural Research, 2013-09-11)Predacious phytoseiid mites, Euseius kenyae (Swirski and Ragusa) plays a major role in management of coffee thrips and other pests such as Phytophygous mites in coffee. Their conservation under various agro-ecosystems ... -
