Walborg Thorsell (1919-2016) was a Swedish veterinary scientist who studied mosquitos and mosquito repellents because there was talk about malaria infected mosquitoes being used as biological warfare. Thorsell found that diethylamide was more effective than the common repellent deet.
Thorsellia bacteria are named after Thorsell because they are found in mosquito species that are common vectors for malaria in Africa, Asia, and South America. Thorsellia is founded in waters were mosquitoes breed, and can live in alkaline conditions, and grow faster in blood culture. Alkaline conditions are found in mosquito larvae. Thorsellia has also been found in mosquitos that are carriers of West Nile virus and encephalitis.
