Yvonne Geissbühler: Ecology and epidemiology of integrated malaria vector management in Dar es Salaam, Tanzania

PhD-thesis, University of Basel, Faculty of Science (2008)

The goal of the study is to further the understanding of urban malaria epidemiology, larval ecology and adult mosquito behavior and to show their implications for implementing Integrated Vector Management (IVM) in urban Africa. The research was carried out in the frame of the Urban Malaria Control Program (UMCP) in Dar es Salaam (Tanzania) which began implementing a community-based but vertically managed larval control program using microbial larvicides. The results show that mosquito and human behavior have characteristic features in urban environments; biting behavior of the main malaria vectors change in urban settings. Therefore, personal protection offered by insecticide-treated bednets (ITNs) is still useful, but should be complemented by vector control methods such as environmental management or larviciding. The UMCP demonstrates the success of a malaria control program integrating larviciding, which could be easily adapted by other African cities as a cost-effective option for malaria prevention.
