Today, indoor house-spraying with residual insecticides is still a major part of malaria control programmes throughout the world. De Meillon wrote several standard works on insects of medical importance and has authored or co-authored over 180 scientific papers. Succeeding De Meillon as Head of Department was Prof. Fritz Zumpt who was an acknowledged expert on myiasis flies and wrote the standard text on this group of insects. He also produced a major text on the lice of the sub-Saharan region. The main thrust of research in the department today centres on malaria vector mosquitoes as this disease is still the most devastating disease in rural Africa.
Valuable research is conducted in both in South Africa and various other African states.
The Department of Medical Entomology maintains close ties with other research organisations involved in similar work and collaboration is encouraged.
