Vector Ecology and Environment

Our research interests include any thing from ecology to molecular biology of medically important arthropods, particularly mosquitoes that transmit pathogens such as Malaria parasites and dengue virus in Africa and Southeast Asia. We are also interested in their relationships with environmental variables and development of environmentally friendly vector control tools.

Activities

For dengue virus vectors, we revealed the geographical distributions of two subspecies of Aedes aegypti in East and South African regions. Our study also found that the genetic structure of Ae. aegypti populations in endemic areas in Africa are similar to those of Southeastern populations. The results suggest that the African mosquito populations were introduced from the overseas. To test the hypothesis further, we are currently conducting various studies, including a study on virus susceptibility.
For reducing malaria risk, we are evaluating the effectiveness of new insecticides and insecticide treated mosquito nets (ITNs) in Kenya and Malawi. We are also developing a malaria early warning system in Africa.
