Biological control of water fern, Salvinia molesta (Salviniaceae), in South Africa

Until recently, water fern, Salvinia molesta D.S. Mitchell, in South Africa was only surpassed by water hyacinth as an aquatic weed and was particularly troublesome in regions with a subtropical climate.

Description
Summary:Until recently, water fern, Salvinia molesta D.S. Mitchell, in South Africa was only surpassed by water hyacinth as an aquatic weed and was particularly troublesome in regions with a subtropical climate. Following impressive successes elsewhere around the world, the weed has been successfully controlled biologically in South Africa using the weevil Cyrtobagous salviniae Calder and Sands. In this review, the recent introduction and establishment of C. salviniae in South Africa is described, and the future management of S. molesta is discussed.
