PMI VectorLink Study Findings of Invasive Malaria Vector in Africa Published

PMI VectorLink published its findings on the invasive malaria vector Anopheles stephensi in Ethiopia in Malaria Journal this week.

Collection of An. atephensi larval from breeding containers in Awash Subah, Ethiopia. PMI VectorLink collected An. stephensi larvae in urban and rural sites in eastern Ethiopia. An. stephensi larvae were not found in western Ethiopian sites.

The study, “An update on the distribution, bionomics, and insecticide susceptibility of An. stephensi in Ethiopia, 2018-2020,” looks at the distribution, bionomics, insecticide susceptibility, and transmission potential of the vector.

One of the primary malaria vectors in South Asia, the vector was first reported in Africa in 2012 in Djibouti. Since then, the vector has been found in Ethiopia, Somali, and Sudan, and poses grave concern malaria control.

While more data is needed, the study will help inform Ethiopia’s vector control decisionmakers on how to reduce this vector’s population and its spread of malaria as it unveils more information on this invasive species in Africa. Read more here.
