Possible biocontrol agents for Hydrilla
Angela Bownes- ARC-Plant Protection Research Institute
Hydrilla (Hydrilla verticillata) is a submerged aquatic macrophyte, native to Asia and Australia.
Hydrilla has invaded Josini Dam, KwaZulu-Natal, South Africa, and which is a serious economic and environmental aquatic weed.
Hydrilla is genetically diverse, with a wide distribution in its native range hence biotype matching was an important consideration for the biological control programme.
Two leaf-mining flies, Hydrellia pakistanae and Hydrellia sp. of different origin have been under consideration for release against South Africa hydrilla, a monoecious biotype of Malaysian/Indonesian origin.
