How the invasive mosquito Anopheles stephensi is changing malaria risk in Ethiopia
Official title: Malaria Epidemiology and Vector Biology of Anopheles stephensi across Rural and Urban Landscapes in Ethiopia
Funded at University of California-Irvine · NIH-11498201 · Data updated 2026-11-12
This project looks at how the invasive mosquito Anopheles stephensi spreads in cities and rural areas of Ethiopia and what that means for people at risk of malaria.

Who could benefit from this research
✓Could help
Ideal participants are people living in urban or rural communities in Ethiopia where An. stephensi has been found who can take part in household surveys, allow mosquito trapping near their homes, or provide samples for testing.
✕Less likely to help
People who live outside the invaded regions or do not take part in local surveys or sampling are unlikely to see direct benefits from this project.
What this research studies
If you live in an affected area, you may see teams from U.S. and Ethiopian institutions mapping where An. stephensi lives and how it behaves in both cities and rural sites. Field teams will trap mosquitoes near homes, test them for malaria parasites, and study how the mosquitoes bite and breed. The project will try new surveillance tools and control methods to find practical ways to lower mosquito numbers and reduce malaria risk. Lab work will help explain mosquito biology so local health programs can use better tools to protect communities.
Why it matters
Potential benefit: If successful, the work could lead to better mosquito surveillance and control that lowers malaria cases in affected Ethiopian communities.
How similar studies have gone: Similar mosquito surveillance and control programs have reduced malaria in other regions, but targeted work on the invasive An. stephensi in Africa is relatively new and still developing.
