The water hyacinth is introduced in the U.S. and quickly becomes an invasive species.
The higher densities of Biomphalaria sudanica occur in habitats with the Common Water Hyacinth Eichhornia crassipes in Lake Victoria.
It is a sap-feeding mirid that removes a considerable amount of chlorophyll from water hyacinth (Eichhornia crassipes, Pontederiaceae).
The larvae feed on a wide range of aquatic plants, including Hydrilla verticillata, Eichhornia crassipes, Pistia stratiotes, Nymphaea and Potamogeton species.
Other than extensive diversions, exotic introduced, fast-growing and water-consuming plants, such as water hyacinth and hydrilla, are also leading to reduced flows.The United States government has recently attempted to slow or stop the progress of these weeds by introducing insects and fish that feed on the invasive plants.
