Mosquito Larval Habitats In A Semiarid Ecosystem In Eritrea: Impact Of Larval Habitat Management On Anopheles Arabiensis Population, Josephat Shililu, Charles Mbogo, Tewolde Ghebremeskel, John Githure, Robert Novak

All Peer-Reviewed Publications

This study investigated the impact of larval management and the temporal variation in larval productivity in Eritrea, a semiarid ecosystem. Results of this study show that mosquito breeding persists throughout the year mainly in stream bed pools. Anopheles arabiensis production in the ephemeral natural aquatic habitats such the streambed pools was high throughout the year and negatively associated with rainfall (r = -0.288, P = 0.047). High densities of An. arabiensis larvae were also recorded from canals and drainage channels at wells and communal water supply points. The numerous water supply locations and wells help sustain malaria transmission by serving …

Distribution And Relative Importance Of Lepidopteran Cereal Stemborers And Their Parasitoids In Uganda, T. Matama-Kauma, F. Schulthess, J. A. Ogwang, J. M. Mueke, C. O. Omwega

All Peer-Reviewed Publications

Infestation levels and parasitism of lepidopteran stemborers on maize were assessed in four agroecological zones (AEZ) in Uganda. The indigenous noctuid Busseola fusca Fuller (Noctuidae) and the invasive Chilo partellus Swinhoe (Crambidae) were the most important stemborers recorded. C. partellus represented 77% of the stemborers in the Eastern AEZ while B. fusca was dominant in the other AEZs, accounting for 60-79%. The proportion of infested plants was between 16% and 45% and borer density between 0.2 and 1.0 borers per plant. There was no clear relationship between damage and stem tunneling, which is often used to estimate yield loss. Telenomus …

On The Limits Of Sexual Health Literacy: Insights From Ugandan Schoolgirls, Shelley Jones, Bonny Norton

Institute for Educational Development, East Africa

This article makes the case that current conceptions of sexual health literacy have limited relevance to the Ugandan context because they assume that knowledge of unsafe sexual practices will lead to changes in behavior and lifestyle. Drawing on a longitudinal case study with 15 Ugandan schoolgirls in rural Uganda from August 2004 to September 2006, this study argues that despite being well-informed about the risks and responsibilities of sexual activity, poverty and sexual abuse severely constrained options for these young women. Although many believed in the value of abstaining from sexual activity until marriage, they engaged in transactional sex to …

Manual For The Identification Of Grass Stemborers And Associated Parasitoids In Kenya, Alberto T. Barrion, Robert S. Copeland, Zeyaur R. Khan

icipe Manuals

Foreword

This manual illustrates many of the stemborers and associated insects of grasses in Kenya, and provides keys for their identification. It can be used together with icipe’s booklet A Primer on Grass Identification and Their Uses in Kenya, which provides diagnostic and pictorial information on grass species that abound in and around agricultural lands in Kenya.

It is of paramount importance to identify stemborers and their natural enemies associated with grasses to implement ways of using native grasses to manage insect pests in farmers’ fields. Wild grasses may act to repel or physically block pests of cereal crops, …
