Some Aspects of the Ecology, Behaviour and Vectorial Capacity of the Tsetse Fly Glossina Austeni Newstead.
(Kenyatta University, 1992)A study was undertaken in the south coast of Kenya, on the tsetse fly species, Glossina austeni Newstead. The objective was to investigate its population ecology, behaviour and vectorial capacity. The main aspects studied ... -
The role of arthropod vectors in the transmission of lumpy skin disease in cattle
(2004)Lumpy skin disease (LSD) is an economically crippling disease of cattle with epizootic occurrence particularly after the onset of the rainy season. Biting arthropods have been implicated as vectors of lumpy skin ... -
Breeding of the honey bee (apis mellifera l.) and its potential for royal jelly production in Kenya
(Kenyatta University, 2004-07)Royal jelly is a creamy, milky white, strongly acidic and highly nitrogenous substance secreted by the hypopharyngeal and mandibular glands of worker honey bees at the ages of 5 - 15 days of age. The jelly is fed to queens ... -
Assessment by performance attributes of indigenous egg parasitoids (hymenoptera: trichogrammatidae for biocontrol of african bollworm (helicoverpa armigera) in Kenya
(Kenyatta University, 2004-08)Trichogrammatid egg parasitoids are used extensively for the control of several lepidopteran pests in many areas of the world. They ar~he most promising biological control agents for inundative releases against the African ... -

Impact assessment of natural enemies on stem borer populations and maize yield in three Agro ecological Zones in Mozambique
(Kenyatta University, 2007-05)Lepidopteran stem borers are the major pests limiting the production of maize and grain sorghum under subsistence farming conditions of Southern Africa. Classical biological control has traditionally emphasized the control ... -
Diversity, Ecology and population dynamics of Lepidopteran stem borers in Kenya
(Kenyatta University, 2009-07)Stem borers are important field insect pests of maize [Zea mays L.] and sorghum [Sorghum bicolor (L.) Moench] in Africa. They account for more than 30% yield losses depending on fhe composition of the pest community. A ... -
The ecology and economic potential of wild silkmoth Anaphe Panda (Boisduval) (Lepidoptera:Thaumetopoeidae) in the Kakamega forest
(2011-07-11)The superiority of silk as a textile fibre has been recognized from time immemorial, the luxurious look: sleek feel and lustre of silk fabric are unquestionably inimitable. The demand for silk is constantly increasing ... -
Spatial distribution and biology of Gonometa postica Walker (Lepidoptera: Lasiocampidae) with reference to its key parasitoids on Acacia species in Mwingi, Kenya
(2011-07-11)The African wild silkmoth, Gonometa postica Walker produces silk of high quality. A study on the spatial distribution and biological and biology of G. postica on host and non-host plants and the parasitism rates and ... -
Host suitability and interspecific competition among the West African stemborer egg parasitoid Telenomus isis and other indigenous egg parasitoids in Kenya
(2011-07-11)In East and Southern Africa (ESA), the noctuid Busseola fusca and the exotic crambid Chilo partellus are among the most important lepidopteran stemborer pests of cereal crops. In western Africa, the scelionid egg parasitoids ... -
Bioecology of the new invasive fruit fly Bactrocera invadens (Diptera:Tephritidae) in Kenya and its interaction with indigenous mango-infesting fruit fly species
(2011-07-11)Bactrocera invadens Drew, Tsuruta & White (Diptera: Tephritidae), an alien invasive fruit fly species of Asian origin was first detected in Kenya in 2003. This pest has rapidly spread across sub-Saharan Africa and is ... -

(2011-07-11)Mother-to-child transmission (MTCT) of HIV-1 is responsible for infection of hundreds of thousands of infants every year. It is estimated that 600,000 newborns are infected yearly worldwide, with MTCT accounting for 90% ... -
Effect of ABO/Rhesus blood group phenotypes on immunosurveillance to plasmodium falciparum malaria in children in Kisumu town, Kenya
(2011-07-11)Malaria is the world leading cause of deaths among the tropical infectious diseases particularly in children and pregnant women. A safe and effective vaccine would have been the easiest way to control this disease, but the ... -
Predicting productive larval habitats for anapheles gambiae in lowland Western Kenya
(2011-07-11)Larval habitats of the anopheline vectors of human malaria form an integral part of transmission because they produce the adult female (i.e., vector) stage. In this study, conducted in a region holoendemic for Plasmodium ... -
