Development of a new tool for malaria mosquito surveillance to improve vector control

Malaria transmission is influenced not only by vector abundance, but as well by demographic traits such as vector species and age structure, as these influence the intensity by which the …

Demonstrating complete disruption of residual malaria transmission by eliminating Anopheles funestus mosquitoes from rural Tanzanian villages

In rural south-eastern Tanzania, where malaria prevalence has reduced by >60% since 2000, low-to-moderate transmission still persists despite very high coverage with long-lasting insecticidal bednets. Like in most residual transmission …

Nicodem James Govella

Research Scientist and Head of Environmental Health & Ecological Sciences

Dr. Govella received his PhD from the Liverpool School of Tropical Medicine in 2010, his thesis focused on vectors of human malaria. Dr. Govella has research experience in vector-borne disease transmission and their control. His main research interest is in the behaviour of disease vectors and understanding what the drivers of those behaviours are and how those change or impact the vector control interventions. He has been granted a Wellcome Trust Training Fellowship award to investigate the potential for malaria vector adaptation (2014-2017), and has completed theoretical modelling work on vector-control impact. Dr. Govella has made key contributions to the development and testing of interventions to target outdoor malaria and filariasis transmission; and developing disease mosquito surveillance tool alternatives to accurately measure and characterize transmission indicators, host-seeking behaviour, and evaluate impact of vector-control interventions to guide policy makers. For example, he invented the Tent Trap for monitoring densities of outdoor-biting mosquitoes. This device has proven highly effective and it has been successfully used in large-scale programmatic surveillance applications. Dr. Govella has published a number of papers in peer-reviewed Journal; holding a number of research grants, and has been affiliated to large consortiums, such as AvecNet and MTC. He is a member of Vector Control Working Group (VCWG) of the Roll Back Malaria (RBM), Ifakara Health Institute’s Ethical Review Board (IRB), and Pan African Mosquito Control Association.
