Biological control initiatives against water hyacinth in South Africa: constraining factors, success and new courses of action.
The success of biological control initiatives undertaken against water hyacinth in South Africa has been variable, despite the establishment of six natural enemy species (five arthropods and one
Life History and Laboratory Host Range ofEccritotarsus catarinensis(Carvalho) (Heteroptera: Miridae), a New Natural Enemy Released on Water Hyacinth (Eichhornia crassipes(Mart.) Solms-Laub.)
Abstract A mirid,Eccritotarsus catarinensis(Carvalho), was studied as a potentially damaging natural enemy for water hyacinth, (Eichhornia crassipes(Mart.) Solms-Laub.), in South Africa. In the
PCR-based fingerprinting using AFLPs as a tool for studying genetic relationships in Lactuca spp.
AFLP markers were evaluated for determining the phylogenetic relationships Lactuca spp. Genetic distances based on AFLP data were estimated for 44 morphologically diverse lines of cultivated L.
Plant pathogens and biological control of weeds in South Africa: a review of projects and progress during the last decade.
This review focuses on subsequent progress and projects against terrestrial and aquatic weeds in South Africa and includes research that was either initiated just prior to the previous review, completed during the 1990s or which is still in progress.

The longterm management of alien aquatic plants in South Africa relies on the prevention of new introductions of aquatic plant species that could replace those that have been controlled, and on a reduction in nutrient levels inSouth Africa's aquatic ecosystems.

The biological control of aquatic weeds in South Africa: Current status and future challenges
A review of the biological control programme on waterweeds in South Africa shows significant reductions in the extent of invasions, and a return on biodiversity and socio-economic benefits through the use of this method.
