title: The control of Simuliidae (Diptera, Nematocera) in South African rivers by modification of the water flow volume.
abstract: It was found that the build-up of simuliid numbers subsequent to the construction of dams in the Vaal and Orange Rivers could be successfully prevented by periodic, artificially controlled reductions in the water-levels in these rivers.
