Effect of Herbivore-induced Plant Volatiles of Brachiaria Brizantha on Neighbouring Maize for Chilo Partellus Management in Suba District, Homa-bay County, Kenya

Magara, Henlay Juma Otieno (Kenyatta University, 2014)

The Lepidopteran stemborer Chilo partellus is a key constraint to cereal production in most resource-poor farming systems as it causes damage to the crop, accruing up to 80%. When plants are damaged by herbivorous insects, ...
Health Seeking Behaviour in Malaria Treatment by the Fishing Community of Rusinga Island, Western Kenya

Oduke, Jacqueline, E. (University of Nairobi, 2014)

Literature on health and diseases indicate that people perceive diseases variously. People develop their own views and beliefs about the causes, symptoms, modes of transmission and therapy choices, which then influence ...
An assessment of lepidopteran stemborer species distribution in relation to diversity of wild host grasses in maize and sorghum growing zones in Kenya

Ong’amo, George Otieno (Kenyatta University,, 2005)

Lepidopteran stemborers pose a serious constraint to maize (Zea mays L.) and sorghum (Sorghum bicolor L.) production in Africa. Despite the achievements made through biological, chemical and cultural control approaches, ...
Evaluation of 2-Butanone as a Substitute for Carbon Dioxide in Malaria Mosquito Attractants

Mburu, Monicah, M. (University of Nairobi, 2013)

Odor-baited traps (OBTs) are increasingly being considered for use in sampling, surveillance and control of malaria mosquitoes. Most odor baits contain carbon dioxide, which apparently enhances trap catches given its role ...
Assessment of damage and yield losses on maize by the lepidopterans Chilo partellus (Crambidae), Busseolafusca (Noctuidae) and Sesamia calamistis (Noctuidae)

Akhusama, Etabale (Kenyatta University,, 2006)

Lepidopteran stem borers are among field insect pests responsible for the low maize production in sub-Saharan Africa. In Kenya, Chilo partellus Swinhoe (Pyralidae), Busseola fusca Fuller (Noctuidae) and Sesamia calamistis ...
Release Kinetics Of A Synthetic Tsetse Allomone Based On Waterbuck Odour From A Tygon Silicon Dispenser

Musyoki, Shem (University of Nairobi, 2006)

This study was conducted in order to develop an appropriate dispenser for the waterbuck-derived repellent for tsetse flies. The waterbuck-derived repellent consisted of pentanoic, hexanoic and heptanoic acids, guaiacol, ...
Characterization of Microhabitats of Arboviral Mosquito Vector Larvae on Three Islands of Lake Victoria, Kenya

Ogao, Onchuru Thomas (Kenyatta University, 2014)

Mosquitoes are the primary vectors of arboviral infections. As there are no vaccines or effective therapeutic treatments for these diseases, vector control is an important approach for curbing their circulation or transmission. ...
Comparative and Functional Analysis of Tsetse Fly Aquaporins

Aroko, Erick Onyango (Kenyatta University, 2014)

Tsetse flies (Glossina sp) are the vector of African trypanosomes, the causative agents of sleeping sickness in man and Nagana in cattle. The insect is strictly hematophagous, taking in significantly high quantities of ...
